Triclosan: Soap ingredient can trigger liver cancer in mice, warn scientists
A chemical ingredient of cosmetics, soaps, detergents, shampoos and toothpaste has been found to trigger liver cancer in laboratory mice, raising concerns about how safe it is for humans, scientists said. Triclosan, a commonly used anti-bacterial agent added to bathroom and kitchen products, promotes the growth of liver tumours in mice fed relatively large quantities of the substance, a study has found.
California agency orders battery recycler to fund cleanup
The California Department of Toxic Substances Control (DTSC) has announced an enforcement order against Exide Technologies, headquartered in Milton, Georgia, that requires the battery recycling company to set aside sufficient funds to close its Vernon, California, facility, when that event occurs. Additionally, the DTSC has ordered the company to take measures immediately to address contamination in the community surrounding the Vernon smelter.
Connecticut's paint recycling program has successful 1st year
New Haven Register
The state’s paint recycling program, which was launched in July 2013, collected more than 240,000 gallons of leftover paint in its first year, the Connecticut Department of Energy and Environmental Protection said recently. The program is managed by PaintCare, a nonprofit organization that also administers similar recycling programs in four other states. Connecticut’s program was the third in the nation.
Production of magnetic nanoparticles with new structures
Iranian researchers succeeded in the production of nanoparticles with new structures and special magnetic properties. The method proposed by the researchers is cost-effective and simple, and it is considered as green chemistry due the application of palm oil.
Recycler abandons millions of pounds of e-waste
Stone Castle Recycling, previously one of Utah’s largest recyclers of electronic waste, has abandoned its three facilities and the owner is missing, according to the Basel Action Network, an e-waste watchdog group.
The company has ceased all operations and has left behind several warehouses and yards filled with an estimated 7,600 tons of toxic electronic wastes and charred residues.
New process transforms wood, crop waste into valuable chemicals
Environmental Research Web
Scientists recently disclosed a new method to convert lignin, a biomass waste product, into simple chemicals. The innovation is an important step toward replacing petroleum-based fuels and chemicals with biorenewable materials, says Shannon Stahl, an expert in "green chemistry" at the University of Wisconsin in Madison.
Driving towards success with biomass-derived petrol
Chinese scientists have overcome previous limitations to generate high octane number petrol from biomass-derived γ-valerolactone, an organic compound that is already often blended in small amounts with petrol or diesel. Using an ionic liquid catalyst, the conversion churned out a 2,2,4-trimethylpentane-rich substance with an octane number of 95.4, the highest reported for biomass derived fuel.
Paint industry program encourages recycling
Recycling leftover paint is easier in Minnesota thanks to a program that allows painting contractors and households to drop off leftover cans of latex and oil paint at more than 100 retail drop-off sites throughout the state.
The program will add an additional 60 locations by summer 2015.
New versatile process efficiently converts biomass to liquid fuel
Researchers have demonstrated a new process to convert all biomass into liquid fuel, and the method could make possible mobile processing plants. The researchers at Purdue University filed a patent application on the concept in 2008 and have now demonstrated that it works in laboratory experiments, said Rakesh Agrawal, the Winthrop E. Stone Distinguished Professor of Chemical Engineering.
Making chemistry green
The New York Times (opinion)
For nearly 40 years, the Food and Drug Administration has wrestled with regulating the chemicals triclosan and triclocarban as they have become among the world’s most ubiquitous environmental contaminants. Designed to kill bacteria, they have been added to antibacterial soaps, cosmetics and other consumer products despite longstanding concerns about their impacts on humans and the environment.
Artificial sweeteners pollute streams
In the past few decades, diners have been turning increasingly to soft drinks and foods sweetened with fake sugar. The idea is to get the sweet taste without loading up on calories. But a new study finds an environmental cost to these sweeteners: in short order, they can end up polluting lakes and streams.
Robots put to work on e-waste
University of New South Wales researchers have programmed industrial robots to tackle the vast array of e-waste thrown out by Australians every year. The research shows robots can learn and memorise how various electronic products are designed, enabling them to be disassembled for recycling at ever-increasing speeds.
