Studies find factories release pharmaceuticals

Federal scientists testing for pharmaceuticals in water have been finding significantly more medicine residues in sewage downstream from public treatment facilities that handle waste from drugmakers.Early results from two pivotal federal studies compare wastewater at treatment plants that handle sewage from drugmakers with those that do not. The studies cover just a small fraction of the 1,886 pharmaceutical manufacturing facilities counted in a 2006 U.S. Census report.In one study, samples taken at two treatment plants down the sewer line from drugmaking factories contained a range of pharmaceuticals — among them opiates, a barbiturate and a tranquilizer at "much higher detection frequencies and concentrations" than samples taken at other plants, according to preliminary research by the U.S. Geological Survey.One drug, the muscle relaxant metaxalone, was measured in treated sewage at concentrations hundreds of times higher than the level at which federal regulators can order a review of a drug's environmental impact.Based on secrecy agreements with the researchers, the treatment plants were not identified.USGS researcher Herb Buxton, who co-chairs a White House task force on pharmaceuticals in the environment, said it's important that federal scientists test the pharmaceutical industry's claims that their wastewater is not a meaningful source of pharmaceuticals in water."It's critical that those types of assumptions are confirmed through real testing," said Buxton.In another study, Environmental Protection Agency researchers tested sewage at a municipal wastewater treatment plant in Kalamazoo, Mich., that serves a major Pfizer Inc. factory. Bruce Merchant, Kalamazoo's public services director, provided data that showed unusually high concentrations of the antibiotic lincomycin entering the plant, a drug the factory was producing around the time samples were collected."There's some product going down the drain," said Merchant.While nearly all the lincomycin was removed during wastewater treatment, some did survive. According to a separate 2008 study, lincomycin combined in minute concentrations with several other drugs that also have been detected in surface water made human cancer and kidney cells and fish liver cells proliferate.Biologist Francesco Pomati, at the University of New South Wales in Sydney, Australia, was so concerned with the findings that he and his colleagues warned that chronic exposure to the combination of drugs via drinking water could be "a potential hazard for particular human conditions, such as pregnancy or infancy."In earlier experiments, lincomycin acted as a mutagen, changing genetic information in bacteria, algae, microscopic aquatic animals and fish.Pfizer spokesman Rick Chambers said that while the company does not test wastewater from the facility for the drugs made on site, "compliance with all environmental, health and safety laws is imperative to our business operations worldwide."The two domestic studies follow a burst of recent research in Asia and Europe that has started to link factories to the presence in water of drugs including the antibiotic sulfamethoxazole, the pain reliever diclofenac and the anticonvulsant carbamazepine, as well as an antihistamine, female sex hormones and aspirin.Researchers in India, where multinational companies have increasingly turned for the manufacture of raw pharmaceutical ingredients, found that 100 pounds a day of the antibiotic ciprofloxacin enters a river from a wastewater treatment plant that processes sewage from dozens of pharmaceutical makers.In Switzerland, a study sponsored by drugmaking giant Roche documented that 0.2 percent of active pharmaceutical ingredients escape during its own processing. That kind of loss rate doesn't sound like a lot until it's projected out over the entire annual production of drugs worldwide. Studies in Taiwan and China also suggest drugmaking plants discharge product.All of which raises questions about U.S. manufacturing."Is it as bad in the U.S. as it is in India? Probably not. But it does make me think we should test," said Kyla Bennett, a former EPA enforcement officer who is now an ecologist and environmental attorney. 
 

Viewpoint] An unhappy China

China can proudly say as a creditor that America is not right. Unless the United States gives China the treatment it deserves, China will help no more.
April 06, 2009
Lately, the international media have been paying attention to a book published in China titled “China is Unhappy.” The book, written by five writers known for their nationalistic tendencies, became an instant bestseller after it was published in mid-March.

But why is China unhappy? Why is the world paying attention to this book?

Let’s look at some excerpts:

“Learn from America? The United States is virtually bankrupt already. However, it is not actually going bankrupt because it is like a water demon. Countries around the world have lent to the United States so much that they are all concerned about America’s collapse. The United States lives like a parasite. Its economic system is like a cancer to the global economy. Learn from America? China can learn only bad things from America.”

And: “The United States has no money and its manufacturing sector is crippled. Consumers don’t save and only indulge in spending. This led to the subprime mortgage crisis. Some Chinese still worship Western ideas. They are overwhelmed by the United States, underestimate the caliber of the Chinese people and are about to miss the opportunity that comes along with the global financial crisis.”

Then, finally: “The Chinese people are great. China has to save mankind. Amid the financial devastation, China must lead the world to overcome the crisis. The Chinese people have been given such a critical task.”

The international media are watching the book because it clearly demonstrates the nationalistic global perspective rapidly emerging in China. From this point of view, the Chinese deserve to be unhappy. The source of Chinese pride is the millennium-old conviction that China is the center of the world. However, after the First Opium War in 1840, China was torn apart by the Western powers. And in 1949, after almost 100 years, the communist government was established, and the territory was somewhat united. And during the 40 years of the Cold War, China was overwhelmed by the Soviet Union and the United States.

Since the fall of the Soviet Union and Eastern Europe, China has been working hard for 20 years under American hegemony.

Now in 2009, the 60th anniversary of the Communist Party regime, China can recover its pride. With the money earned from selling goods to the United States, China bought U.S. Treasury bonds. Now that the United States is in economic crisis, China can proudly say as a creditor that America is not right. Unless the United States gives China the treatment it deserves, China will help no more.

This is China’s subjective perspective. Having been hurt and forced to struggle, many Chinese think this way. Of course, it is not the official position of the Chinese government. Yet the absolute majority of the Chinese people shares the perspective, and some of the leaders are considered to be in covert agreement.

Last February, Xi Jinping, the most likely successor of President Hu Jintao, visited Mexico. During a meeting with local ethnic Chinese, he criticized the attitude of the West for pointing a finger at China when the West was at fault. Official Chinese media did not cover the story.

The important thing is that the Chinese government is moving in this direction gradually yet firmly. And in reality, the United States and other countries cannot resist such a move.

More importantly, the Korean Peninsula is most directly influenced by the emergence of China. In particular, China is the only country in the world that can influence North Korea.

If China were not there for Pyongyang, it is doubtful whether North Korea could have developed nuclear and missile programs. If China had not helped the North, it could not have afforded to decline America’s food assistance. Would the North have been able to launch a missile despite U.S. pressure? Could it open and close Kaesong Industrial Complex as it pleases? If China really wants to lead the world, it should understand that some countries, including Korea, could become unhappy because of China. In addition, Korea needs to remind China what it’s like when the shoe is on the other foot. 

 

Darden Students Aim to Wring Pollution -- And Millions -- Out of India's Dirty Water

E-mail Print PDF

April 2, 2009 — If you live in the "Knitwear Capital of India," your water probably doesn't taste very good, if you can drink it at all. That's because dyeing cotton for Banana Republic T-shirts, Reebok socks and truckloads of similar clothing bound for Europe and the United States requires tons of water, and the small textile firms that dominate the industry in the South Indian state of Tamil Nadu cannot afford traditional wastewater treatment, so they simply dump toxin-filled water into the local rivers.

That's the problem that a team of University of Virginia business students has a plan to solve. And their plan has been getting some validation recently.

Darden School of Business students Baijnath Ramraika, Ravi Yekula and Chip Ransler won two business plan competitions in the past week, raking in $5,000 at Wake Forest University last weekend and pocketing $10,000 on Tuesday from the Darden-U.Va. Business Plan Competition. The top finish in the Social Entrepreneurship category at the Wake Forest Elevator Competition also netted the team a share of $65,000 in legal and marketing services. This week's success follows three other wins in the past six months that garnered a total of $3,000.

The business, called Clean India, will use algae and sand filtration to treat and recycle wastewater as a "pay-for-use" service.

The garment makers of Tirupur, India generate about 100 million liters of chemical dye-laced wastewater per day, and generally face no penalties for dumping it into the local water supply, Yekula explained. To make their pollution less obvious, the companies typically add toxic de-coloring chemicals to the water before discharging it. The resulting contamination has caused such a shortage of clean water that the local price of clean water has doubled in the past five years. Many places in India, China and other developing countries face similar water supply challenges, giving Clean India lots of long-term growth potential.

But several factors make Tirupur an ideal spot to launch the business, Yekula said. For years, many Tirupur businesses got water by drilling wells, but the growth of this practice has completely depleted the local groundwater. The local municipal water supply is poorly developed, and so manufacturers purchase 60 percent to 70 percent of their water needs from private suppliers, who typically deliver it by the truckload. Clean India will also use tanker trucks to shuttle contaminated water to their treatment facility, and to deliver the cleaned and recycled water.

The large, up-front costs of traditional wastewater treatment equipment are not economically viable for these small garment makers, Yekula said, so Clean India plans to sell them recycled and cleaned water as an on-demand service, costing slightly less than they now pay for delivered clean water. The first target customers are a number of textile firms that are clustered together in a Tirupur industrial park. Three of the firms have already signed on as ready customers whenever the business gets online.

Clean India will use algae and sand filtration to treat the contaminated water. The algae is grown in a patented bioreactor, and then introduced to open ponds of wastewater. The algae breaks down the toxic elements in the water into nonharmful elements. Then a sand filter captures any remaining sediments and particulates. The whole process takes about five days for a given batch of wastewater. The process can be customized by identifying strains of algae that are best suited to removing particular pollutants.

The process is labor-intensive, as workers must move water from pond to pond and separate the algae every day.  This harnesses India's low-cost labor as a substitute for the high capital costs of traditional wastewater treatment equipment costing hundreds of thousands of dollars, Yekula said.

The modular system can be expanded as new customers are added. A 5-million-liter pilot treatment facility will cost $1.5 million. It should pay for itself in 18 months, Yekula said, and produce $4 million in revenue and $1 million in profits by the end of five years. By year five they hope to expand to 26 plants.

"India has a scarcity of water," Yekula said. "This problem is huge, but we think Clean India has a solution that actually makes a difference. ... It's not only solving a social problem, it's doing it in a very profitable way.”

Clean India has not yet lined up financing for the pilot facility, but investors and venture capitalists have expressed interest, Yekula said. "With the global economic meltdown, people are looking for places to invest where there will still be at least some growth, and India is still growing."

"I'm from India myself, so I feel a deep empathy for any kind of problem-solving in India," said Saras Sarasvathy, an associate professor at Darden who has been an adviser to the team.

"If Ravi and Baijnath can show their model works in one place, they could go lots of places, and they now have the education and vision to think about how to scale it up," Sarasvathy said. "That's what separates them from being just another successful entrepreneur in India. But I tell them, 'You have to get that first piece done. But if you can get it done, it could be a big solution.'"

G20 governments must share a vision of world's futureEconomic and environmental recovery must go hand in hand
Comments (…) Digg it Steve Howard guardian.co.uk, Wednesday 1 April 2009 08.30 BST Article historyIt is time to act on climate change. The science is clear: greenhouse gas emissions must be cut by over 60% below current levels by 2050. And the reductions must start now. The greatest barriers to achieving this reduction are political.

This Thursday, world leaders from the G20 countries – representing 85% of the world's economic output – will meet in London to address the global financial crisis.

With the summit's stated aims of taking action to stabilise financial markets, strengthening the global economic system and putting the global economy on track for sustainable growth, this is a timely opportunity for governments to develop a shared vision on the world's future.

The current financial crisis – the worst since the 1930s – is prompting government intervention to help stimulate economic growth. This represents a unique opportunity to invest in a sustainable future.

Recent analysis by HSBC of the economic stimulus packages that have passed or are pending in 15 nations found that these countries plan to invest more than $3tn to stimulate their economies over the next decade.

Suddenly, the amounts needed for combating climate change – in the order of tens of billions per annum over the next decade – don't seem so large or unrealistic.

Last year, Lord Stern, author of the 2006 Stern Review, estimated that we could keep climate change in check at a cost of less than 2% of global GDP, compared to the 5-20% of global GDP that would be lost because of unabated global warming. This seems like a good investment on anyone's terms.

And it seems that a number of governments are beginning to think so too as evidenced by the green components — defined as low carbon power, energy efficiency, water treatment and pollution control — of the various economic stimulus packages announced over the last few months. However, despite the wide range of this green content — ranging from 0% in Poland and 7% in the UK to 38% in China and 81% in South Korea — the average of 15% falls well short of what is needed.

According to the UN Environment Programme, 1% of global GDP, or approximately US$750bn, should be invested on greening the world economy to create momentum for real change.

And this is not just a long-term equation. Low-carbon policies and investment are a win-win situation in the short-term too. Almost a third of the 2020 greenhouse gas abatement required saves money through more efficient energy use.

The US stimulus packages promises to double clean energy capacity and are expected to create around 2.5 million green jobs.

In a report published last year by the Climate Group, China is showing some of the strongest growth rates in low-carbon industries in the world, with the country's green investment package likely to give a further boost to its $17bn renewable energy sector which already employs around one million people.

In the UK, thousands of jobs could be created with green offshore initiatives.

Economic and environmental recovery must go hand-in-hand and – if well-designed –will be mutually reinforcing.

Halving global emissions by 2050 will require what's been described as "an industrial revolution in a third of the time" of the last one. This goal is within reach. Current technologies can deliver and the economic and political backdrop has fundamentally shifted, opening up a new world of possibilities for a global deal and a global shift to a low-carbon economy.

Business leaders from around the world have stated their desire to work with governments to provide practical advice on how to best link the recovery and low-carbon agendas to exploit this huge growth potential.

We must take this opportunity. We simply cannot allow ourselves to fail. The G20 summit in London gives world leaders the chance to show us that we will not.

WABAG Finalizes Sludge Treatment Plant In Beijing

E-mail Print PDF


The Xiaohongmen plant in south-east Beijing is the largest anaerobic sludge stabilisation plant ever to be completed by WABAG. Using the very latest technology, the sewage sludge from the wastewater treatment plant is dealt with in five bioreactors with a total volume of 60,000 m3. The five digester towers are impressive structures that now number among the technical sights in Beijing.

The Xiaohongmen wastewater plant in the Chaoyang District, which lies in the south-eastern corner of Beijing, is one of China's largest treatment facilities. 600,000 m3 of wastewater derived from the area along the basin of the Liangshui River, where over two million people live, are treated daily. WABAG has completed a sludge treatment plant, which is equipped with advanced technology, for the stabilisation of the sludge emanating from biological wastewater cleaning.

During the allocation of the project, the WABAG concept convinced the responsible commission due to the superior know-how available with regard to reliability, safety and energy consumption. The Beijing city administration and the World Bank jointly financed the project, which has cost around EUR 15M.

Advanced, energy-efficient technologies for low environmental impact
The main plant units consist of mechanical sludge thickening, anaerobic sludge stabilisation, mechanical sludge dewatering with phosphor removal, and biogas recycling. With thickening as an initial phase, this concept allows a reduction in sludge volume and thus of the hydraulic load in the bioreactors in which the sewage sludge is subjected to controlled fermentation. The product of this process is flammable gas, which is converted into energy in heating boilers and gas motor units. This power is employed to drive fans, while in conjunction with the heat from biogas-fired boilers, waste heat is used for sludge heating in the digester towers and plant infrastructure heating. All in all, these measures add up to considerable savings with regard to plant operational costs, as well as a marked improvement in the overall CO2 balance of the Xiaohongmen wastewater treatment plant. The stabilised sewage sludge has a dry solids content of around 3 per cent. Following subsequent sludge dewatering, this content is raised to around 25 per cent, which significantly reduces volume and thus saves landfill space for further disposal.

Opening up of an alternative energy source and a contribution to climate protection
As a result of anaerobic stabilisation and the possibilities for the energetic use of the resulting biogas, sewage sludge is becoming increasingly important as an alternative source of energy. Depending upon the size of the respective plant, wastewater treatment facilities can cover up to 100 per cent of their own energy requirements, or the generated power is fed into the public grid for external use.

If untreated sewage sludge is deposited on landfills, this involves enormous volumes and over the years, landfill gas, which plays an active role in the greenhouse effect, leaks into the atmosphere. Above all, the methane released has a major impact, as it is 21 times more greenhouse active than carbon dioxide. In terms of CO2 equivalents, the Xiaohongmen plant achieves a reduction in greenhouse gases of some 140,000 t annually.

Using the BIOZONE-AD, which has been furthered developed by WABAG, up to 40 per cent more methane can be extracted from sewage sludge, thus providing a notable improvement in both energy yield and climate protection. In addition, the ozone employed cracks micro-pollutants in the sewage sludge such as endocrine disruptors.

Sludge treatment is a market with huge potential
In line with the increasing number of wastewater treatment plants, the market for effective sludge treatment plant is growing rapidly. As Herbert Hofstätter, the head of WABAG's office in Beijing, makes clear, "With the turnkey realisation of the Xiaohongmen sludge treatment plant, WABAG has passed a milestone in the process of establishing itself in this important area and we have also further consolidated our reputation as a reliable partner in the Chinese market." WABAG has been active in China for over 20 years and has installed more than 70 water and wastewater treatment plants.

Around the world, the WABAG name stands for innovative and successful solutions in the water engineering sector. As an internationally respected expert group, we act as a systems specialist and full service provider with a focus on the planning, installation and operation of drinking and wastewater plants for local government and industry in the growth markets of Asia, North Africa, Middle East, the Central and Eastern Europe states.

With VA TECH WABAG India and VA TECH WABAG Austria, the WABAG Group represents a leading multinational player with more than 1,000 employees in 18 countries and disposes over unique technological know-how, based on innovative, patented technologies and long-term experience.

Since 1995, WABAG has completed over 900 water and wastewater plants worldwide. Through the conservation and ecological use of the world's most valuable resource, WABAG has made a sustained contribution to an improvement in the quality of life of well over a hundred million people. WABAG is thus one of the world's leading partners for investments in a future that is worth living.
