The project – which Tesla says took six months to complete from inception to operation, with the battery installation itself taking about five weeks – was unveiled on Tuesday afternoon (Australian time) by the California based company via its various social media channels.

According to ReNews, the €11 million storage array, located at the Terhills resort, is pooled with a mix of demand response assets from industrial and commercial consumers, and is one of the largest batteries in Europe contributing to the grid.

While a fraction of the size of the 100MW Hornsdale Power Reserve “big battery” in South Australia, the Belgian battery bank will be used for similar “grid balancing” purposes on the European grid – as the video below explains.

It will combine with various demand response services to provide around 32MW of grid capacity. The number of Powerwalls – 140 – suggests storage capacity of 28MWh, but this will depend on the final configuration.

Meanwhile, in Australia, work has begun on the Bulgana Renewable Energy Hub in Victoria which will see the state’s first combine wind farm and battery storage, including a 20MW/34MWh Tesla battery.

Tesla is also working on another large-scale battery storage project – the Gannawarra Energy Storage System, which will add a 25MW/50MWh Powerpack battery system to Victoria’s biggest solar farm, the 50MW Ganawarra project in the state’s north-west.

And earlier this month, Tesla CEO and chief visionary Elon Musk let slip about a soon-to-be announced new big battery project that would dwarf the SA installation.

Musk said the new project would be announced within a few months – he did not say where it will be installed – and that at 1GWh it would would be eight times bigger than Hornsdale.

“The utilities have really loved the battery pack. I feel confident that we will be able to announce a deal at the gigawatt hour scale within a matter of months,” Musk told a conference call following the release of the company’s March quarter results.

Water Shortages to Be Key Environmental Challenge of the Century, Nasa Warns

Water shortages are likely to be the key environmental challenge of this century, scientists from Nasa have warned, as new data has revealed a drying-out of swaths of the globe between the tropics and the high latitudes, with 19 hotspots where water depletion has been dramatic.

Areas in northern and eastern India, the Middle East, California and Australia are among the hotspots where overuse of water resources has caused a serious decline in the availability of freshwater that is already causing problems. Without strong action by governments to preserve water the situation in these areas is likely to worsen.

Some of these hotspots were previously undocumented or poorly understood: a region in north-western China, in Xinjiang province, has suffered dramatic declines despite receiving normal amounts of rainfall, owing to groundwater depletion from industry and irrigation.

The Caspian Sea was also found to be showing strong declines owing to similar forces, which is resulting in a shrinking shoreline. Previously, this change had been attributed to natural variability, but the new report demonstrates it was caused in large part by the diversion and extraction of water from rivers that feed it, for agriculture and industry. This depletion mirrors the well-known fate of the disappearing Aral Sea in the same region: because the Caspian Sea is much bigger it would take millennia to disappear altogether, but its shrinking shoreline and pollution will cause major problems throughout its borderlands.

The comprehensive study, the first of its kind, took data from the Nasa Grace (Gravity Recovery and Climate Experiment) satellite mission to track trends in freshwater from 2002 to 2016 across the globe.

“What we are witnessing is major hydrologic change. We see for the first time a very distinctive pattern of the wet land areas of the world getting wetter, in the high latitudes and the tropics, and the dry areas in between getting drier,” said James Famiglietti, of the Nasa Jet Propulsion Laboratory in California, and co-author of the paper published today in Nature. “Within the dry areas we see multiple hotspots resulting from groundwater depletion.”

Climate scientists, including the Intergovernmental Panel on Climate Change, have predicted such a global trend. The new paper’s authors said it was too soon to confirm whether their observations were definitely the result of global warming, but said their results showed a “clear human fingerprint” on the global water cycle.

The study is unprecedented, as the Grace data allowed the scientists to see in detail the changes in freshwater resources around the world, even where locally amassed data has been scarce or unavailable. By linking the satellite data with local monitoring, they added another crucial dimension.

Marc Stutter, of the James Hutton Institute in Aberdeen, who was not involved with the study, said: “Such new data add insight into how we manage both obvious surface waters and hidden subsurface water stores [as] the satellite techniques see vital hidden water reserves under our feet, much like an x-ray to see the health of our unseen water reserves.”

He said it provided an early warning that could allow better management of water resources across the world, which was needed.

In northern India, groundwater extraction for irrigation of crops such as wheat and rice have caused a rapid decline in available water, despite rainfall being normal throughout the period studied. “The fact that extractions already exceed recharge during normal precipitation does not bode well for the availability of groundwater during future droughts,” the authors said, adding that the much-discussed melting of Himalayan glaciers was of only minor significance in the period studied.

In Iraq and Syria, widespread over-reliance on groundwater has resulted from the construction by Turkey of 22 dams on the Tigris and Euphrates rivers, over the last three decades. This has made the area the biggest hotspot identified by the study, outside of sparsely or uninhabited regions such as Antarctica and Greenland, with water resources nearly a third below their normal state.

Jonathan Farr, senior policy analyst at the charity WaterAid, said governments must take note of the findings and increase their role in preserving water resources and providing freshwater to people in a sustainable manner. “This report is a warning and an insight into a future threat. We need to ensure that investment in water keeps pace with industrialisation and farming. Governments need to get to grips with this,” he said, pointing to estimates that between $30bn and $100bn of investment was needed per year to provide freshwater where needed.

Sustainable solutions were available, he said. “We have been solving the problem of getting access to water resources since civilisation began. We know how to do it. We just need to manage it, and that has to be done at a local level.”

Providing access to clean water provides knock-on benefits to health, education, equity and the economy, he added, so investment in water assets yields both economic and social dividends.

New Labelling Helps UK Shoppers Avoid Plastic Packaging

Foto-ilustracija: Pixabay

A new plastic-free “trust mark” is being introduced today, allowing shoppers to see at a glance whether products use plastic in their packaging.

The label will be prominently displayed on food and drink products, making it easier for consumers to choose greener alternatives.

UK supermarket Iceland and Dutch supermarket chain Ekoplaza – which introduced plastic-free aisles earlier this year – will start using the new labelling, alongside Teapigs teabags, but campaigners hope others will follow suit.

“Our trust mark cuts through the confusion of symbols and labels and tells you just one thing – this packaging is plastic-free and therefore guilt-free,” said Sian Sutherland, co-founder of A Plastic Planet, the campaign group behind the scheme.

As well as items obviously wrapped in plastic, scores of everyday products – from tinned beans to tea bags – have some plastic in their packaging.

Sutherland said she hoped the new labelling system would revolutionise the way people shop and lead to a radical reduction in plastic waste.

“Finally shoppers can be part of the solution not the problem,” she added.

There has been growing concern about the devastating impact of plastic on the oceans and wider environment. Plastic pollution is now so widespread that it has been found in tap water, fish and sea salt – with unknown consequences for human health.

Iceland will begin to adopt the new labelling system on relevant own-label products this month, and roll it out across its range, which it has said will be free of single-use plastic packaging by 2023.

Ekoplaza said it would be rolling out the trust mark in 74 outlets across the Netherlands.

A Plastic Planet has been campaigning for supermarkets to introduce plastic-free aisles and there has been growing pressure on the major retailers to do more to tackle the problem.

Earlier this year the Guardian revealed that supermarkets are responsible for 1m tonnes of plastic waste a year.

Iceland managing director, Richard Walker, said: “With the grocery retail sector accounting for more than 40% of plastic packaging in the UK, it’s high time that Britain’s supermarkets came together to take a lead on this issue.

“I’m proud to lead a supermarket that is working with A Plastic Planet to realise a plastic-free future for food and drink retail.”

From Plankton to Mahi-Mahi and Beyond: Toxic Plastic Is Traveling Up the Food Chain

Even a hundred yards out from the stern of the old steel sloop, the fish at the end of the line looked enormous. And it was strong: As it leapt up out of the water in an attempt to free the hook from its mouth, its long body—green and yellow and speckled with fluorescent blue—slashed violently, unspooling more and more line. The sailor at the end of the reel had to put up a significant fight to avoid losing his rod in the vast blue Pacific.

Photo-illustration: Pixabay

“That is a mahi-mahi, the most beautiful fish in the world!” called out the ship’s captain. At the beginning of the third week of what would turn out to be a 23-day scientific expedition across the Eastern North Pacific Gyre—a highly polluted ocean vortex that swirls clockwise from the California coast to the Hawaiian Islands and back again—a fresh fish was a welcome source of food for his crew of eight.

After several minutes of an intense duel, the sailor reeled in the fish, smiling.

That smile soon faded a bit. After the sailor was done separating the fish’s thick flesh from skin and bone, he cut open its stomach as requested by the ship’s lead scientist. Inside was a small flying fish. The scientist directed the sailor cut open that second fish’s stomach.

Out rolled two small pieces of plastic.

These plastic bits were what’s classified as “microplastic” due to their small size—less than .04 inches in diameter.

“That’s not too appetizing,” said the scientist, Kristian Syberg, a professor of environmental risk at Roskilde University in Denmark who was aboard the ship to sample the seawater for plastic.

Scientists who study plastic, like Syberg, are just beginning to understand the implications of microplastic and even smaller pieces of plastic called nanoplastic on the marine food web. Fishers, beachgoers and scientists are finding a growing number of marine animals—from live-caught fish to deceased seabirds and whales—with microplastic in their bodies. While the issue has only been studied in-depth for a handful of years, the latest research suggests these tiny pieces of plastic are capable of being transferred from organism to organism, wreaking havoc all the way up the marine food web—possibly all the way to humans.

At the Cornish Sea Sanctuary in the UK, Plymouth Marine Laboratory Ph.D. student Sarah Nelms compared the levels of microplastic found in the bodies of wild-caught Atlantic mackerel and the scat of the captive gray seals to which they were fed over the course of 16 weeks in 2016. She found microplastic in half the seal scat she studied, and in one-third of the mackerel fed to the seals. She posited that the mackerel—considered secondary consumers because they are one step above the bottom of the marine food web—ate microplastic particles along with their normal diets of zooplankton and this plastic was passed on to the seals.

“The seals are not exposed to any other sources of plastic,” Nelms told me recently.

Yet the plastic still ended up in their systems. In a paper published this February in the journal Environmental Pollution, Nelms and her coauthors noted that her team took “extensive contamination control measures” to prevent the seals from being exposed to other sources of plastic during the study. “We were therefore able to conclude that the microplastics we found in the seal scats came via the fish.”

The fishes’ bodies contained a higher number of plastic particles than the seal scat did, particularly microfibers, which crumble off fishing rope or are shed from clothing when washed. Nelms said this could mean the unaccounted-for plastic particles might be getting caught inside the seals’ bodies, causing unknown harm.

Microplastic is known to absorb chemicals from ocean water. When marine creatures consume microplastic, they’re also getting a dose of toxins. Syberg has studied this so-called “vector” effect where microplastic acts as a transporter of toxic chemicals. He said persistent organic pollutants, called “POPs” for short, are most worrisome because, once consumed, they tend to adhere to organisms’ fat cells where they are metabolized by the body and cause health problems.

Throughout history humans have released huge amounts of POPs into nature, where they persist and spread for decades without degrading. These chemicals, which include pesticides, industrial chemicals and unintentional pollutants such as DDT, PCBs and hexachlorobenzene, are considered highly toxic to humans and wildlife. They are proven to cause health problems such as allergies, reproductive and hormone problems, immune system disorders and cancer.

For this reason, and because there’s still so much scientists don’t known about how plastic acts inside the bodies of living things, Nelms said, “I would consider any amount of plastic inside an animal to be too much.”

Plastic’s movement up the marine food web appears to start with the ocean’s smallest animals, and even in these creatures can cause severe harm. Independent plankton scientist Richard Kirby recently filmed a common plankton species called an arrow worm found off Plymouth, in the UK, eating a tiny plastic microfiber. The fiber blocked the worm’s gut, stopping the movement of copepods—its food source—through its body. Eventually this would kill the worm—though Kirby pointed out that doesn’t always happen with microplastic.

“In some cases the microplastics will pass through the animal or can be retained and eaten by another animal when the plankton itself is eaten,” said Kirby.

Widespread deaths of plankton caused by microplastic would certainly disrupt the marine food web. But their consumption is already changing the health of the oceans: Microplastic has been found in middle-ocean and deep-sea fish, which, like mackerel, are prey to ocean top predators, like seals or mahi-mahi. With each bite, plastic is moving up the food web, all the way to fish sold for human consumption in markets across the world. Kirby said scientists must urgently perform more research to gain a better understanding of the quantity and geographical distribution of microplastics in order to get a clearer picture of its effects on the oceans.

After my expedition across the North Pacific, Syberg took the plastic pieces and a chunk of the mahi-mahi’s flesh back to his lab in Denmark. He hopes to compare the chemicals found in the plastic with the chemicals found in the fish flesh to see if the vector effect had begun to act on the fish. While results of his chemical analyses are pending, he told me when I visited him in his lab a few months after our sailing trip that “I don’t even have to test the mahi-mahi and plastic to tell you that both of these things contain toxic chemicals.”

At sea, yes, we ate that fish. Just one more link in the chain.

Philippines Plans Manhattan-Sized Green City

Photo-illustration: Pixabay

The Philippines has an ambitious plan to deal with its capital’s pollution woes—build an entirely new, sustainable city 75 miles from Manila.

Photo-illustration: Pixabay

The proposed New Clark City will be larger than Manhattan and house up to two million people, Business Insider UK reported May 9.

The project’s current price tag is $14 billion, and it will be funded through private-public partnerships.

New Clark City will feature innovative green technology like electric, driverless cars and buildings designed to be energy efficient and conserve water. Two-thirds of the city’s area will be devoted to farms and green spaces in an attempt to reduce carbon dioxide emissions.

The New Clark City website describes it as “A destination where nature, lifestyle and business, education, and industry converge into a global city based on principles of sustainability.”

The city is also designed to be resilient to disasters caused by climate change. At 184 feet above sea level, it should be largely safe from flooding. Further, the green space means that rivers have room to expand without flooding infrastructure, the Thomson Reuters Foundation reported in March.

“The objective is not simply to build a disaster-resilient city, but rather a successful, innovative and economically competitive city that is also disaster-resilient,” RAND Corporation researcher Benjamin Preston told the Thomson Reuters Foundation.

The project is being developed by the Bases Conversion and Development Authority (BCDA), owned by the Philippines’ government, and the Singapore urban planning firm Surbana Jurong.

Surbana Jurong CEO Heang Fine Wong told CNBC that the city would act as a “twin city” to Manila.

Manila’s Pasig River is so polluted that it can only support janitor fish and water lilies, according to Sciencing. Air pollution in Manila is also 70 percent higher than the World Health Organization’s recommended safe levels, the Philippines’ Department of Environment and Natural Resources reported.

According to the Thomson Reuters foundation, it is also one of the densest cities in the world, so experts think the construction of New Clark City will relieve pressure on the capital and allow it to focus on making itself more sustainable and resilient as well.

“(It) has the potential to take pressure off Manila so that Manila can also invest in building a more resilient future,” Lauren Sorkin, director for Asia-Pacific with 100 Resilient Cities, told the Thomson Reuters Foundation.

According to BCDA President Vince Dizon, the government is working to develop the new city as quickly as possible while making sure it retains its green design.

“We need to strike a balance between fast-paced development that maximises value for the private sector, and protecting open spaces and making the city walkable, green and resilient,” Dizon told the Thomson Reuters Foundation.

Currently, the BCDA is working to complete the New Clark City sports facility in time for the Philippines to host the Southeast Asian Games in 2019, breaking ground on the complex April 25, the New Clark City website reported.

Proposed Future EU Budget Embraces Increased Climate Action

Foto-ilustracija: Pixabay

Today the European Commission has published its proposal for the post-2020 EU budget, kicking off the political battle over the rules and priorities that will govern EU spending in the period 2021-2027. The Commission has chosen climate action to be one of the top priorities for future EU funding.

Photo-illustration: Pixabay

The proposal indicates how big the future EU budget should be, how it should be filled, and what the main priorities for future funding should be.

Climate action has been identified as one of the main priorities for future funding. While the current budget for the period 2014 to 2020 has a 20% climate action spending target to be implemented horizontally throughout all spending programmes, the new proposal sets apart 25% of the EU budget for climate action. This 5% increase compared to the current climate spending results in a total of €320 billion for climate action during the entire period (2018 prices).

Markus Trilling, finance and subsidies policy coordinator at Climate Action Network (CAN) Europe, said: “The European Commission acknowledges the EU budget’s role in tackling climate change. More money is needed to boost European and international climate action. So far the green potential of the EU budget has regrettably been untapped. It is a good sign that the European Commission considers increasing the share of the future budget dedicated to climate action.”

“To bring European economies closer to the Paris Agreement, the post-2020 EU budget must spend at least 40% on the decarbonisation of energy, industry and mobility systems, and ensure not one cent will benefit fossil fuel-related activities and infrastructure. In the upcoming negotiations, Member States must support French President Emmanuel Macron’s plea for a 40% share of the next EU budget to be dedicated to climate action and the ecological transition.”

In Blow to Monsanto, India’s Top Court Upholds Decision That Seeds Cannot Be Patented

Foto-ilustracija: Pixabay

In an another legal blow to Monsanto, India’s Supreme Court on Monday refused to stay the Delhi High Court’s ruling that the seed giant cannot claim patents for Bollgard and Bollgard II, its genetically modified cotton seeds, in the country.

Photo-illustration: Pixabay

Monsanto’s chief technology officer Robert Fraley, who just announced that he and other top executives are stepping down from the company after Bayer AG’s multi-billion dollar takeover closes, lamented the news.

Fraley tweeted, “Having personally helped to launch Bollgard cotton in India & knowing how it has benefited farmers … it’s sad to see the country go down an anti-science/anti-IP/anti-innovation path…”

Monsanto first introduced its GM-technology in India in 1995. Today, more than 90 percent of the country’s cotton crop is genetically modified. These crops have been inserted with a pest-resistant toxin called Bacillus thuringiensis, or Bt.

Citing India’s Patents Act of 1970, the Delhi High Court ruled last month that plant varieties and seeds cannot be patented, thereby rejecting Monsanto’s attempt to block its Indian licensee, Nuziveedu Seeds Ltd., from selling the seeds.

Because of the ruling, Monsanto’s claims against Nuziveedu for unpaid royalties have been waived, as its patents are now invalid under Indian law. Royalties will now be decided by the government.

Indian environmentalist Vandana Shiva, who is known for her fierce activism against corporate patents on seeds, called the top court’s move a “major victory” that opens the door “to make Monsanto pay for trapping farmers in debt by extracting illegal royalties on BT cotton.”

She also said in a video Monday in front of the Supreme Court, “Our sovereignty is protected, our laws are protected. Our ability to write laws in the public interest [and] for the rights of farmers through the constitution are protected.”

“The Earth will win. Seed will win. Monsanto will lose,” Shiva added.

A Monsanto India spokesman told Reuters the case will be submitted for an expedited preliminary hearing on July 18.

“We remain confident on the merits of the case. India has been issuing patents on man-made biotech products for more than 15 years, as is done widely across the globe,” the spokesman said.

Electric Buses Put the Big Hurt on Fossil Fuel Companies

Photo-illustration: Pixabay

Change is a funny thing. You can’t see it, hear it, feel it, or taste it, but one day you look around and suddenly, there it is. Isbrand Ho, managing director for BYD in Europe, tells Bloomberg he was laughed out of the room at a conference in Belgium 7 years ago when he introduced a prototype of the electric bus his company had developed. “Everyone was laughing at BYD for making a toy,” he recalls. “And look now. Everyone has one.”

Photo-illustration: Pixabay

Everyone is right. While China has seen the biggest surge — Shenzen, BYD’s home city, now has 16,359 electric buses — they are making inroads into public transportation fleets around the world. They are in London, Poland, Brazil, Portugal, and Korea. Oslo plans to add 70 electric buses by next year and Paris is making plans to add 1,000 of them over the next 5 years.

There are now almost 400,000 electric buses in the world — the vast majority of them in China — according to BNEF. Every five weeks, China adds 9,500 more, equal to London’s entire bus system. All those electric buses are beginning to have an impact on the demand for diesel fuel. By the end of this year, Bloomberg believes electric buses will be displacing 279,000 barrels of diesel fuel per day. That’s about as much as Greece consumes on a daily basis.

“This segment is approaching the tipping point,” says Colin Mckerracher, head of advanced transport at the London-based research unit of Bloomberg LP. “City governments all over the world are being taken to task over poor urban air quality. This pressure isn’t going away, and electric bus sales are positioned to benefit.”

BYD estimates its buses have logged 10 billion miles and saved 1.8 billion gallons of diesel fuel over the past 10 years. According to Ho, that means as much as 18 million tons of carbon dioxide pollution has been avoided, which is equivalent to removing 3.8 million cars from the world’s roads.

Keeping all that pollution out of the air pays major dividends. Shenzen once had some of the worst smog in all China, which is saying something in a country where smog has become a major contributor to poor health, accounting for 1.6 million extra deaths in 2015 according to Berkeley Earth.

“The first fleet of pure electric buses provided by BYD started operation in Shenzhen in 2011,” Ho says. “Now, almost 10 years later, in other cities the air quality has worsened while – compared with those cities — Shenzhen’s is much better.”

How the UK Fell out of Love with Wet Wipes

Photo-illustration: Pixabay

On the eighth-floor isolation ward of London’s University College Hospital, nurses have two lines of defence against the spread of life-threatening diseases. First are the airtight double lobbies in every room. Second – and, arguably, more importantly – are the disinfectant wipes they rely on to prevent the spread of germs and viruses.

Photo-illustration: Pixabay

For nurse consultant Annette Jeanes, the disposable flannels are a godsend that allow her and her staff, not only to protect themselves from superbugs such as C difficile and other viruses, but also to make the most of their time, a crucial factor in the National Health Service.

“It’s hard to imagine a time when the NHS didn’t use wipes,” she declares as she surveys the length of T08 ward. “Our nurses are one of our greatest resources and we don’t have enough of them. Wipes have made their lives easier and freed them up to do other things.”

Similar arguments could be heard the length and breadth of the UK this week after the government announced plans to address the worst effects of wet wipes following a host of revelations about the ubiquity of the throwaway towels.

While the NHS – which is by far the biggest public sector user – can make a strong case for the necessity and benefits of disposable hygiene products, the picture is very different in wider society, where wipes can be more aptly described as a consumer luxury that chokes waterways and threatens wildlife.

Until now, the rise of the wet wipe has been irrepressible; its history a mirror of global inequality, consumerism and short-term thinking. In the 60 years since the first was deployed, usage has surged to an estimated 450bn a year – or about 14,000 every second.

Market research suggests wipes and other throwaway hygiene items are near-perfect markers of haves versus have-nots. In poor nations, usage is close to zero. But once average salaries rise to $1,500 per month, women begin to buy sanitary products. From $3,500, parents are willing to spend on disposable nappies. Once incomes hit $8,000, people splash out on wipes.

Age is also a factor. Younger generations whose bottoms were cleaned as babies are more inclined than their parents and grandparents to use wipes. Busy mums are the main market. In the US, 22 million Americans used pre-moist cloths 31 times or more within a week. Between 2005 and 2015, the surface area of non-woven wipes produced in Europe almost doubled.

The supplanting of cloth napkins, cleaning rags and toilet paper began 60 years ago.

The first pre-moistened, scented napkin was produced in a Manhattan loft in 1958 by a former cosmetics industry employee, Arthur Julius, who later convinced Col Harland Sanders that his finger-lickin’ chicken would sell better if messy eaters could clean up with the Wet-Nap® he had trademarked. Kentucky Fried Chicken has since given away close to a billion wipes. “Enough to reach halfway to the moon,” a spokesman claimed, omitting to mention that disposal will have to be an earthly operation and not a cosmic one.

This is only a tiny fraction of the total. Tweaks to the chemical and manufacturing processes have led to alcohol swabs, baby wipes, airline refreshment towels, disinfecting tissues, antibacterials, makeup removers, insect-repellent towelettes and countertop cleaners.

Julius’ company – Nice-Pak is still the market leader, churning out 150bn wipes per year – almost 5,000 a second. Rival firms spin out more than that number again, but the most modern products have little in common with the original.

Fibres of the paper can now be woven, spun-laced, doused in sanitising isopropyl alcohol, scented, and preserved with anti-fungal agents such as methylisothiazolinone.

But the fastest-growing market in recent years is for damp, chemically-treated alternatives to toilet paper, such as adult moist tissues, toddler care products and feminine hygiene wipes. Unlike baby wipes, they are designed to be flushable. Consumers do not appear to know the difference.

Cities are growing used to reports of subterranean “fatbergs” – giant blobs of congealed grease and other waste that blocks sewers. A study by Water UK found wipes made up 93% of the 300,000 sewer blockages that it deals with each year. Belfast, Denver, Melbourne and Baltimore have all been affected. The fattest fatberg found so far however was in Whitechapel, where sewer workers in hazmat suits had to clear a blockage the size of 11 double-decker buses. When a chunk was later displayed in the Museum of London, one reviewer compared the exhibit to the portrait of Dorian Gray, suggesting the foul-smelling waxy matter was “a kind of collective self-portrait”.

As well as ugly, it is expensive. Blockages cost the UK about £100m every year, according to Water UK’s director of corporate affairs, Rae Stewart: “Water companies spend billions of pounds every year improving water and sewerage services in this country, but our sewers are just not designed to handle these new wipes which clog up the system. Sewer blockages end up costing the country about £100m every year so it’s clear that something needs to change.”

This has contributed to a second wave of pollution of the Thames. Following the contamination of the industrial era, London’s river is now increasingly clogged with the detritus of the consumer age.

Walk along the bank near Hammersmith or Barnes at low tide and many of the exposed rocks are flecked with wet wipes discharged through nearby sewer outlets. These are now the most common item of rubbish found on the riverside, overtaking plastic bottles and cotton buds. The citizen clean-up group Thames21 recently claimed wipes are reshaping the waterbed after finding 5,000 in an area half the size of a tennis court.

Although some are supposed to be biodegradable, the risks do not go away when they break down. Kirsten Downer, campaigns officer for Thames21 fears for the herons and ducks she sees pecking on the dirty clumps in case they suffer the fate of fish.

“Wet wipes break down into microplastics, which can be ingested by marine and riverine animals, including zooplankton, and are entering into the food chain,” Downer says. “More than 70% of Thames flounder surveyed have been found to have plastic in their guts for example and there are concerns that Thames oysters will likely contain microplastic too.” Other sources of plastic – including clothes, cups and bottles – are also to blame.

The problem has also spread along waterways towards the coast.

Over the past 10 years, the Great British Beach Clean – an annual event in which volunteers collect rubbish from shorelines – has recorded a fifteenfold increase in the number of wet wipes. On average last year, they found one every five or six steps.

The government’s promise of tough action on these single-use plastics has yet to be matched with deeds. The Department for Environment, Food and Rural Affairs said it is not planning a full ban on wet wipes, but says it will work with industry to develop plastic-free alternatives and examine which products are most at fault for sewer problems.

Other countries are also taking steps. The European Union is investigating wet wipes as part of a wider study of ocean microplastics. Earlier this month, Australian authorities fined Pental $700,000 for falsely claiming its White King wipes were flushable.

Industry leaders in other countries prefer to stress Britain’s exceptional circumstances, saying the problem here is one of sewers rather than products. “I see issues in the UK that we don’t have in the States, notably the presence of waste on the shoreline,” said Dave Rousse, president of the the US Association of the Nonwoven Fabrics Industry. “This suggests – with a high possibility – that sewers are opening out directly into rivers. The waste water is not being filtered.”

Rather than a ban, he said the best solution was for better markings on packaging and more education of consumers so they can distinguish between more “flushable” wipes – which are made of cellulosic materials (which break up and sink) – and regular thermoplastic wipes (which bind and float). But many environmentalists and water authority officials are unimpressed by the distinction, and the higher price of the more biodegradable products puts off all but one in 10 buyers.

Manufacturers are trying to develop greener products that use wood fibres and other natural materials. There are also calls for a universal ‘Bin it, don’t flush it’ logo on packaging, but the best way to ease the wipe problem is to use them less or stop completely. To help, Thames21 have issued a guide for plastic-free parenting.

For the many individuals and institutions that cannot be weaned, the best bet is to seek the most nature-friendly alternative and to discard items responsibly.

At the University College Hospital, which gets through 90,000 packs of wipes each year, staff are trained to dispose carefully. Only used wipes contaminated by faeces, blood and bodily fluids and deemed to be ‘infectious waste’ are destroyed by incineration. All others are ‘macerated’ or pulped down and recycled.

Specialist medical suppliers are also working on solutions without plastic. They will inevitably be more expensive, but Jeanes supports change: “I can’t see wipes disappearing from the NHS but it’s a good thing if we are questioning whether we can do things in a way that is better for the environment and reduces our own waste.”

The UN Climate Talks Say “Goodbye” to Bonn and “Hello” to Bangkok

Photo: IISD

May negotiations within the United Nations Framework Convention on Climate Change (UNFCCC), held in Bonn, Germany, came to an end. They were imprinted by solving the technical difficulties in preparing the ground for meeting the Paris Agreement goals and shaping the rules that will withdraw the economies of the signatory states towards the future of zero carbon footprint. In the upcoming period, technical guidelines will be given a political character.

Following the tradition of the peace-loving Pacific people, political officials and non-party stakeholders got involved in Talanoa dialogue for the first time. The participants were looking for the answers to the questions: Where are we now? Where do we want to be? How do we get there?

Progress has been made in the field of drafting guidelines for the Paris Agreement – especially when it comes to the global stocktake. Its role will be to review progress and increase ambition, efforts and results of countries’ climate change actions in the five-year cycles.

The deadline for the conclusion of the PA Rulebook is the 24th Conference of the Parties that will take place in the Polish town of Katowice in December. In order to prepare themselves for the event, delegates decided to meet one more time this year. Place and time for the next gathering? Bangkok (Thailand), September.

Are the participants satisfied with the outcome of the meetings in Germany?

Camilla Born, senior policy advisor for E3G, stated: “Negotiations went better than expected. Parties showed they are serious about delivering the Paris Agreement so in Bonn they got down to serious business. The next challenge is to mobilize the political will to get the COP24 outcomes over the line in Katowice.”

Mohamed Adow, on the other hand, has expressed concern about securing financial resources for the system transformation and adaptation in order to neutralize the negative effects of global warming: “The radio silence on money has sown fears among poor countries that their wealthier counterparts are not serious about honouring their promises. This funding is not just a bargaining chip, it is essential for delivering the national plans that make up the Paris Agreement. For the Paris Agreement to be a success we need the Katowice COP to be a success. And for the Katowice COP to be a success we need assurances that sources of funding will be coming.”

Li Shou, Greenpeace representative, spoke about the Talanoa Dialogue. “The architecture is there for ambition to be raised, the Talanoa Dialogue, which has led to a real spirit of cooperation, getting beyond the finger-pointing to remind everyone that we all share the same planet and we all need to do more to protect it. The mood created by Talanoa has to start delivering tangible results in the form of enhanced national targets, and we look forward to the EU and China taking an early lead on this.”, Shou said.

Global Warming Will Depress Economic Growth in Trump Country

Photo-illustration: Pixabay

A working paper recently published by the Federal Reserve Bank of Richmond concludes that global warming could significantly slow economic growth in the US.

Photo-illustration: Pixabay

Specifically, rising summertime temperatures in the hottest states will curb economic growth. And the states with the hottest summertime temperatures are all located in the South: Florida, Louisiana, Texas, Mississippi, Oklahoma, Alabama, Georgia, South Carolina, Arkansas, and Arizona. All of these states voted for Donald Trump in 2016.

This paper is consistent with a 2015 Nature study that found an optimal temperature range for economic activity. Economies thrive in regions with an average temperature of around 14°C (57°F). Developed countries like the US, Japan, and much of Europe happen to be near that ideal temperature, but continued global warming will shift their climates away from the sweet spot and slow economic growth. The question is, by how much?

The new working paper concludes that if we meet the Paris target of staying below 2°C global warming, US economic growth will only slow by about 5 to 10%. On our current path, including climate policies implemented to date (which would lead to 3–3.5°C global warming by 2100), US economic growth would slow by about 10 to 20%. In a higher carbon pollution scenario (4°C global warming by 2100), US economic growth would slow by about 12 to 25% due to hotter temperatures alone.

House Majority Whip Steve Scalise, who represents Louisiana (the second-hottest state), recently introduced a new anti-carbon tax House Resolution. Scalise introduced similar Resolutions in 2013 with 155 co-sponsors (154 Republicans and 1 Democrat) and in 2015 with 82 co-sponsors (all Republicans). The latest version currently only has one co-sponsor, but more will undoubtedly sign on. All three versions of the Resolution include text claiming, “a carbon tax will lead to less economic growth.”

As the economics research shows, failing to curb global warming will certainly lead to less economic growth. Climate policies could hamper economic growth, but legislation can be crafted to address that concern.

For example, as Citizens’ Climate Lobby notes in its point-by-point response to the Scalise Resolution, an economic analysis of the group’s proposed revenue-neutral carbon tax policy found that it would modestly spur economic growth (increasing national GDP by $80 to 90bn per year). With this particular policy, 100% of the carbon tax revenue is returned equally to households, and for a majority of Americans, this more than offsets their increased costs. As a result, real disposable income rises, and Americans spend that money, spurring economic growth.

In short, failing to implement climate policies will certainly slow economic growth, especially in hot, red, southern states. A carbon tax, if crafted smartly, could modestly spur economic growth. Blind opposition to carbon taxes is simply bad for the economy and especially bad for Trump voters.

While the Federal Reserve paper focused on the US economy, developing countries will be made much worse off by climate change. Many third world countries are located closer to the equator, where temperatures are already hotter than the temperature sweet spot identified in the 2015 Nature study. A new paper published last week in Science Advances also found that these poorer tropical countries will experience bigger temperature swings in a hotter world. Because of this combination of hot temperatures with bigger swings in countries with fewer resources available to adapt, these poorer nations are the most vulnerable to climate change impacts.

This is a key moral and ethical dilemma posed by global warming: as an important 2011 study concluded, the countries that have contributed the least to the problem are the most vulnerable to its consequences. Meanwhile, wealthy countries are already lagging behind their promised financial aid to help poor countries deal with climate change.

When evaluating climate policies, it’s important to compare the outcomes to the correct baseline. In a world without a carbon tax or other efforts to tackle climate change, temperatures will continue to rise, which will slow economic growth. That’s the baseline against which climate policies need to be compared.

Thus, even if a carbon tax were to slow economic growth, the question is whether it would slow more or less than in the hotter world without the carbon tax. That largely depends on what the rest of the world does, since the US is just one country representing about 14% of global greenhouse gas emissions. But the rest of the world has agreed to try and limit global warming to 2°C in the Paris climate accords – the US is the only country whose leaders are stupid enough to reject that agreement.

Rejecting climate policies like a carbon tax will ensure that the world misses the Paris targets, resulting in slower economic growth. This will particularly hurt poorer countries and Trump’s base in the South. The Federal Reserve Bank paper notes that these states are already among the least developed in the US, based on the Human Development Index. This means that they already have the weakest economies in the US, and failing to take steps to slow global warming will just hamper their economic growth further yet.

In short, if Trump, Scalise, and the rest of the Republican Party want to prevent slowed economic growth in red states, they should be trying to craft an optimal carbon tax, not blindly rejecting the idea outright.

Are Fossil Fuels out of Fashion at the UN Climate Talks?

Photo-illustration: Pixabay

The United Nations Framework Convention on Climate Change (UNFCCC) prides itself for including both Parties and Non-party stakeholders in their decision making processes. A perspective that is suspicious towards the legitimacy of that approach, however, has appeared during the climate negotiations. What would be its supporters reasoning behind excluding a particular group? The particular group’s interest being conflicted with the backbone of the primary agreement – to limit the production of harmful gases. The situation has continued developing during the UNFCCC gathering in Bonn, Germany, this month.

Photo-illustration: Pixabay

There are three categories of participants at the UN Climate Negotiations : countries (parties), media and observers. The observers are further divided in  the United Nations system and its specialized agencies, intergovernmental organizations (IGOs) and non-governmental organizations (NGOs).

The NGO sector encompasses a wide range of values, which are mutually contrasted – ranging from entrepreneurship, industry and agriculture, through environmental associations, local authorities, indigenous people and the academic community to workers’ federations, women’s unions and youth. Among them, the largest fossil fuel companies such as ExxonMobil, Shell and BHP are also found at the meetings of the United Nations on climate change, many of which have openly lobbied against the original mission of the UN climate convention: reducing greenhouse gases emissions.

Concerned about the impairing effects some of these lobby groups might have on the UN Climate talks, Ecuador, on the behalf of the Like-Minded Developing Countries, opposed the practice of universal access to negotiations for Non-party stakeholders in May 2016.

Ecuador and its like-minded colleagues think that the Paris Agreement on Climate Change has emerged as a mechanism that requires participants to “declare” any conflict of interest (COI) they might have. This block, which has Venezuela, Cuba, Uganda and others in it, is committed to creating a “transparency framework” for everyone associated with the UN negotiations, this to ensure that their role is not destructive, but is going hand in hand with the global climate partnership that was launched in the French capitol in 2015.

We spoke to Walter Schuldt who is the head of the Ecuadorian delegation at the UN Climate convention. “Respect for the objective of the Paris Agreement is needed among parties”, Schuldt said. The Paris Agreement clearly states the need for action towards lowering global emissions, and each organization actively counteracting this objective should be labeled as such. The Ecuadorian delegate stressed there is political will from both his country, the African negotiating group and the NGO sector to advocate for a clear regulating process when involving non-parties in the decision making process.

The United States, the European Union, Norway and Australia strongly oppose the idea. In their opinion, industry is a part of the solution, not the problem, and it should not suffer any restrictions that are being proposed by developing countries. It is normal that in certain situations the states and observers, even among themselves, have views fighting with each other. Non-discriminatory participation without interference of the proposed policy of conflict of interest was further supported by other major producers of pollutants during the negotiations – China, Canada, Russia, Saudi Arabia, Brazil, Japan and Switzerland.

Although both are coming from a county that is not supportive of COI, Norine Kennedy and Jesse Bragg have different attitude on the subject.

Norine Kennedy is a vice president for environment, energy and strategic international engagement in the United States Council for International Business (USCIB). You might have concluded it yourself already but just to announce it officially: Kennedy represents the voice of business at the negotiations, including dirty fuel exploiters.

Kennedy acknowledges that conflict of interest is a very important subject that must be addressed, adding that the business world would not be opposed to building up the conflict provision as long as it is not intolerable only to it. “We want to be part of the discussion”, Kennedy said. “We feel that if the outcome is a strengthening of transparency and due diligence and ensuring that everyone who is here, it is clear who they represent, where their funding comes from, etc. – then there’s no problem with that.” She added that if the results of the process would be discriminatory only to the business sector, they would be strongly against it.

“The Paris Agreement is a treaty about everything. It really is about restructuring the entire system of global commerce. And the system of global commerce is very interrelated, you cannot section out any particular sector, be it agriculture or be it fossil fuels,” Norine Kennedy stated. “As far as the fossil fuel companies go, it’s still a major part of the energy mix globally and will be for some time until other substitutes are affordable.” She emphasized that they are long-term thinking enterprises and that they are aware of the exigency to become cleaner and reduce their carbon emissions in order not to be erased from the business map.

The seed of the fight for establishing rules and definitions regarding conflict of interest within the UNFCCC was planted by Corporate Accountability International (CAI) which presented the secretariat with a petition of 500,000 names calling for the exclusion of fossil fuel companies. CAI’s media director is previously mentioned Jesse Bragg.

He praised developing countries for speaking up on adopting the COI policy as it is necessary if negotiators are going to get the rulebook for the Paris Agreement implementation right and expressed belief that at some point the obstruction from these oil-fueled parties like the US, Australia, Canada would be overpowered by others banding together. “Corporations are accountable to governments, governments are accountable to people,” Bragg professed. “The idea that we need to include them in writing the rules that they need to operate by is ludicrous”, he concluded.

PUSH Sweden is a network for young Swedes, founded in 2013. It “pushes” (pun intended) youth from all around the country to engage in sustainability issues solving and its main channel of communication is internet. One of many focus areas of PUSH Sweden are international climate negotiations. When it comes to negotiating conflict of interest, their stance is clear – they want “people in, polluters out”.

On 8th of May, 8th day of the UNFCCC conference in Bonn, accompanied the Youth constituency, the organization protested in front of World Conference Center, where the event was held, shouting “No coal, no oil – keep the carbon in the soil”. They presented how the Paris Agreement is being torn between two sides – people and polluters.

Asked to put feelings and wishful thinking aside and say who would win in the fight, Tove Lexén, Sitha Björklund and Saga Jonsson agreed: “In the end, we do not think there will be a winner. For each they the negotiations are slowed down and fossil fuels continue to be used – we are in fact all losers.” But as the previous discussions in the UNFCCC raised the topic several times and many states realized the need for COI policy, PUSH Sweden said that they strongly believe that, with that support, people would end up winning.

Lexén, Björklund and Jonsson are explicit that there is no way of cooperation between big oil and people. “How could we cooporate with someone who wins when negotiations fail and humanity loses?”, they wonder.

In conclusion, inspired by PUSH Sweden, we object:

What do we want? Climate Justice! When do we want it? NOW!

When are we going to get it?

We do not know yet.

For now, fossil fuels companies are still welcome at the UN climate talks. The argument on conflict of interest has ended on 8th of May with a resolution… to argue more this time next year.

490,000 Pounds of Toxic Pesticides Sprayed on National Wildlife

Photo-illustration: Pixabay

America’s national wildlife refuges are being doused with hundreds of thousands of pounds of dangerous agricultural pesticides every year, according to a first-of-its-kind analysis by the Center for Biological Diversity.

The Center for Biological Diversity report, No Refuge, reveals that an estimated 490,000 pounds of pesticides were dumped on commodity crops like corn, soybeans and sorghum grown in national wildlife refuges in 2016, the most recent year for which data are available. The analysis was conducted with records obtained by the Center for Biological Diversity under the Freedom of Information Act.

“These refuges are supposed to be a safe haven for wildlife, but they’re becoming a dumping ground for poisonous pesticides,” said Hannah Connor, a senior attorney at the Center for Biological Diversity who authored the analysis. “Americans assume these public lands are protected and I think most people would be appalled that so many pesticides are being used to serve private, intensive agricultural operations.”

The pesticides include the highly toxic herbicides dicamba and 2,4-D, which threaten the endangered species and migrating birds that wildlife refuges were created to protect. Refuge pesticide use in 2016 was consistent with pesticide applications on refuges over the previous two years, the Center for Biological Diversity analysis showed.

America’s 562 national wildlife refuges include forests, wetlands and waterways vital to thousands of species, including more than 280 protected under the Endangered Species Act.

Yet intensive commercial farming has become increasingly common on refuge lands, triggering escalating use of highly toxic pesticides that threaten the long-term health of these sensitive habitats and the wildlife that depend on them.

In 2016 more than 270,000 acres of refuge land were sprayed with pesticides for agricultural purposes. The five national wildlife refuge complexes most reliant on pesticides for agricultural purposes in 2016 were:

  • Klamath Basin National Wildlife Refuge Complex in California and Oregon, with 236,966 pounds of pesticides;
  • Central Arkansas Refuges Complex in Arkansas, with 48,725 pounds of pesticides;
  • West Tennessee Refuge Complex in Tennessee, with 22,044 pounds of pesticides;
  • Tennessee National Wildlife Refuge Complex in Tennessee, with 16,615 pounds of pesticides;
  • Chesapeake Marshlands National Wildlife Refuge Complex on the Eastern Shore of Maryland and Virginia, with 16,442 pounds of pesticides.

Additional findings from the report:

  • Aerial pesticide spraying: In 2016, 107,342 acres of refuge lands were aerially sprayed with 127,020 pounds of pesticides for agricultural purposes, including approximately 1,328 pounds of the notoriously drift-prone dicamba, which is extremely toxic to fish, amphibians and crustaceans.
  • Glyphosate: In 2016 more than 55,000 agricultural acres in the refuge system were treated with 116,200 pounds of products containing glyphosate, the pesticide that has caused widespread decreases in milkweed plants, helping to trigger an 80 percent decline of the monarch butterfly over the past two decades.
  • 2,4-D: In 2016 more than 12,000 refuge acres were treated with 15,819 pounds of pesticide products containing 2,4-D, known to be toxic to mammals, birds, amphibians, crustaceans, reptiles and fish and is likely to jeopardize the continued existence of endangered and threatened salmonids.
  • Paraquat dichloride: In 2016 more than 3,000 acres of corn and soybean crops on refuge lands were treated, mainly through aerial spraying, with approximately 6,800 pounds of pesticides containing paraquat dichloride, known to be toxic to crustaceans, mammals, fish, amphibians and mollusks and so lethal it is banned in 32 counties, including the European Union.

“These pesticides are profoundly dangerous for plants and animals and have no place being used on such a staggering scale in our wildlife refuges,” Connor said. “The Interior Department needs to put an end to this outrage and return to its mission of protecting imperiled wildlife, not row crops.”

Green Energy: Good For The Planet, Bad For Fossil Fuel Workers

Photo-illustration: Pixabay

Current U.S. President Donald Trump, like all candidates, made a lot of promises before the election. One of his biggest was directed towards coal workers, to whom he vowed to end the “war on coal,” and bring back the “beautiful” coal industry. Trump claimed that “clean coal” would ensure that “coal will last for 1,000 years in this country.” (We won’t get into the fact that clean coal doesn’t exist the way Trump thinks it does. That’s a topic for another day.)

Photo-illustration: Pixabay

The problem with all of these promises? As any energy expert will roundly tell you, coal is on its way out. Though coal saw a slight jump in exports in 2017 (thanks to demand from Asia), coal consumption in the U.S. has declined every year for the past decade. It’s largely being replaced by cheap natural gas. China, which has taken over as the globe’s biggest coal consumer, is working to make its coal-fired plants more efficient and to eliminate coal usage altogether in the long term.

That suggests coal workers are being set up for failure. And Trump’s coal-friendly policies simply postpone the inevitable end of this industry.

New research by researchers at Indiana University seeks to address exactly this problem: how can we buoy communities that rely on jobs in fossil fuel industries so that they can transition into a future of green energy?

“The energy transition will bring many benefits to society,” said Sanya Carley, Indiana University (IU) associate professor in the School of Public and Environmental Affairs, in a press release. “But the benefits, as well as the costs, will not be dispersed proportionately across society.”

Carley and her co-authors used a tool called the Vulnerability Scoping Diagram, which has previously been used to identify communities susceptible to the impacts of natural hazards and climate change, to identify geographic areas and individuals that will feel the brunt of the clean energy transition.

Unsurprisingly, they found that the most vulnerable communities were those places where fossil fuels play a large role of the local economy, as well as places where individuals cannot afford the increased costs of cleaner energy. For example, the researchers found that counties in Texas, California, Hawaii, and New York would face the greatest financial difficulty from renewable portfolio policies, in which states require a certain portion of electricity to be generated from renewable sources.

The authors suggest that the tool could be used to target these populations for special programs, such as job retraining, or financial assistance.

“It is important to document adverse effects of policies, not in an attempt to undermine their credibility or efficacy, but to better understand their limitations and unintended consequences,” said co-author David Konisky, an associate professor in the IU School of Public and Environmental Affairs, in the press release.

It’s definitely better for everyone in the long run to handle the end of the fossil fuels with compassion for the people whose work relies on them. Helping those who are the most affected by the switch could even speed up the transition. It might even identify towns with workers that might be good candidates to employ in the rapidly-growing renewable energy sector.

Promises aside, coal’s heyday is indisputably over. And given the adverse affects coal had on both human health and the environment, that’s a good thing. If policy-makers take vulnerable populations more into account and help them move towards a future reliant on renewable energy, maybe they’d be on board, too.

California Poised to Be First State to Require Solar Panels on New Homes

Photo-illustration: Pixabay

California is set to require solar panels on new homes and low-rise apartment buildings starting in 2020, the first such mandate in the country and the state’s latest step to curb greenhouse gas emissions.

Photo-illustration: Pixabay

“Adoption of these standards represents a quantum leap in statewide building standards,” said Robert Raymer, technical director for the California Building Industry Association. “You can bet every other of the 49 states will be watching closely to see what happens.”

Raymer spoke before the California energy commission approved the requirement on Wednesday, alongside new regulations to improve ventilation and indoor air quality.

The commission estimates solar panels would boost construction costs for a single-family home by roughly $10,000. But consumers would get that money and more back in energy savings, according to the commission.

California has positioned itself as the nationwide leader on clean energy, pushing for more electric vehicles on the roads and fewer emissions from residential and commercial buildings.

“This is a very bold and visionary step that we’re taking,” said David Hochschild, one of the energy commission’s five members.

The move still needs backing from the state’s building standards commission. The state updates its building codes, including energy efficiency standards, every three years.

Representatives from construction groups, public utilities and solar manufacturers all spoke in support of the plan, which they’ve helped the commission develop for years. No industry groups spoke in opposition.

But Republican legislative leaders argue Californians can’t afford to pay any more for housing in the state’s already extremely expensive market.

“That’s just going to drive the cost up and make California, once again, not affordable to live,” Brian Dahle, the chamber’s Republican leader, said on Tuesday.

About 117,000 new single-family homes and 48,000 multi-family units will be built in 2020, the commission estimates.

The regulations include exceptions when solar panels aren’t feasible, such as on a home shrouded in shade, or cost-effective. Installing storage batteries or allowing community-shared solar generation are available options. The requirement would only apply to newly constructed homes, although many homeowners are choosing to install solar panels with the help of rebate programs.

“This is going to be an important step forward for our state to continue to lead the clean energy economy,” said Kelly Knutsen, director of technology advancement for the California Solar and Storage Association.

If Anything, Sludge Is a Resource

On our path to the European Union, we are bound to adopt a number of laws, among which are regulations related to the treatment of all wastewater and wastewater sludge. Despite the certain opinion which can be heard in our country that the purification of wastewaters isn’t really a necessity, that is backed up by the conviction that a higher concentration of pollution flows into Serbia by the Danube than the one which flows from our country the same way, the projects for the construction of a wastewater treatment systems are in the pipeline. However, sludge remaining after water treatment is escaping the proper attention of the experts and the decision makers. They generally think sludge is a problem that should be somehow dealt with and most often that dealing involves sludge disposal on landfills, which is soon going to be a forbidden technique once we have our laws harmonized with the EU Water Framework Directive. In order to manage this type of problem in a simple way, there is a plan to burn sludge, which is a costly and partial solution. Yet sludge is actually a huge resource if managed in an adequate way.

The technology that allows for a multiple use of water treatment residuals is available in our country through the BBD Group that is representative of the Norwegian company CAMBI, the world leader in the treatment of sludge from wastewater and organic waste. The BBD Group manager Boban Joksic says that capitals such as Washington, Beijing, London, Athens, and Oslo have chosen CAMBI’s sludge treatment plants. Instead of piling up significant costs and thanks to their decision, these cities have been saving money and energy and benefiting from their energy efficient facilities.

– CAMBI has a philosophy: each problem holds a hidden solution. Thus, the enormous amount of sludge that remains after wastewater treatment and whose transport and disposal require huge resources has inspired thinking on how to use it. Existing technologies were simply no longer sufficient. Legal obligations have changed so the directives prohibited the disposal of sludge containing pathogenic organisms. In CAMBI, they have invented a way to use the biological activity of the sludge to the fullest and thus they have come up with a technology known as thermal hydrolysis. This process has enabled obtaining high-quality biogas in the procedure of sludge treatment as well as a significantly better way of use of the residuals for agricultural purposes – explains the director of the BBD Group, stating the fact that the sludge treatment also results in huge savings.

If we know that sludge burning costs an average of 80 to 100 euros per ton and that Belgrade will have it in a raw condition roughly 100,000 tons a year, it is clear that we are not talking about petty savings.

According to estimates, the production of biogas in the process of thermal hydrolysis, which is a pre-treatment to anaerobic digestion, increases up to 30–50%, and the dry remainder whose structure is changed as a result of this process appears to be a first-class fertilizer. For example, in the UK this technology is employed for the treatment of up to 40 percent of the sludge, and that resulted in a new industrial sector.

– After the legislation change, the British authorities set up contracts with companies for the delivery of the fertilizer made in the thermal hydrolysis to farmers and those companies sell it at a price which is a half of the artificial fertilizer’s price. In order to take into account all the possibilities of sludge exploiting, which is still out of our reach, we need to learn a lot about sludge, but first we need to adopt a new approach – says Boban Joksic and informs us that sludge contains a plenty of phosphates and natural phosphorus, and the world is in short of these elements. Using this fertilizer in agriculture, natural nutrients are going back into the soil which becomes ameliorated. The sludge serves as a multivitamin supplement for the soil which was impoverished by nitrogen compounds. It also acts as the best ally in organic production because it doesn’t impede but it stimulates the natural balance necessary for healthy crop farming.

Asked why it is best to use sludge in farming, Boban Joksic claims that the price is the lowest and the level of exploitation is the greatest when we decide to use the remains of wastewater treatment at farms. Any other procedure and an additional process of sludge treatment, starting from disposal at landfills, storage, burning to drying, are considerably more expensive.

– Today we mostly burn and dry sludge in our systems. We took this technology from the Germans who had to process the sludge this way because they had a high concentration of pollutants due to the industrial development. The sludge in our country is not considerably polluted with heavy metals and other pollutants in a way that we would have to burn it. Today, even the Germans tap into some other solutions. On the other hand, they have developed a water purification system by degrees, and we are in a position to skip a few steps – says Boban, pointing out that it is necessary to have knowledge on how to manage sludge just like any other resource. For that matter, one and universal solution doesn’t exist, and it is necessary to come up with a combination of solutions. Since there is a season for fertilization in farming, out of season sludge can be stored and used at urban green spaces, parks, along with the highways, in the forests and elsewhere. In order to be able to use sludge this way it is necessary to adopt a national strategy for the sludge treatment. The drafts were made but we haven’t come a long way.
