The green chemistry poised to turn landfill gas into real energy
Turning landfill gases into hydrogen power isn’t a distant dream. It happens already, particularly in South Carolina, where landfill gas-to-hydrogen conversion projects have advanced beyond pilot or experimental stages into functional energy systems used by large-scale manufacturing outfits, providing heat and/or power.
Landfill gas boosters want the same principle to scale up to use in vehicles, and that’s presented some technological barriers — one of which is the carbon byproduct of the methane-to-hydrogen process.
Carpet recycling jumps 52 percent in 2013
Fourteen percent of carpet was recycled into new products or used to produce energy last year — rather than buried in landfills — according to a new report from the Carpet America Recovery Effort, a nonprofit initiated by both the carpet industry and government agencies to boost carpet recycling nationwide.
This figure may seem like a drop in the bucket against the 3.7 billion pounds of carpet discarded in 2013, but it actually represents a significant improvement over previous years: diversion of carpet from the landfill rose 52 percent from 2012 to 2013.
Enhancing biofuel yields from biomass with novel new method
A team of researchers, led by Professor Charles E. Wyman, at the University of California, Riverside’s Bourns College of Engineering have developed a versatile, relatively non-toxic and efficient way to convert raw agricultural and forestry residues and other plant matter, known as lignocellulosic biomass, into biofuels and chemicals. The patent-pending method, called Co-solvent Enhanced Lignocellulosic Fractionation, brings researchers closer to solving the long elusive goal of producing fuels and chemicals from biomass at high enough yields and low enough costs to become a viable alternative or replacement for petroleum-based fuels and chemicals.
Probes search live cyanobacteria for biofuel-production-boosting proteins
Chemical & Engineering News
For something so tiny and brainless, cyanobacteria have proven awfully hard to push around. The blue-green microbes are promising hosts for biofuel production. Yet attempts to boost output by engineering the microbes’ genomes rarely work in big bioreactors. Researchers at Pacific Northwest National Laboratory think setbacks happen because the biochemistry that regulates fuel compound production isn’t fully understood.
The fight over chemical flame retardants
Lurking inside your bed, your couch, your carpet and the upholstery of your car is a secret arsenal. You can’t see it, you can’t usually smell it and most of the time you’re likely unaware that it’s even there.
The U.S. chemical industry will tell you that it’s there to save lives. And the truth is, in many cases it has. Since 1976 when the federal Toxic Substances Control Act was passed, says the North American FlameRetardant Alliance, deaths from furniture and furnishing fires have dropped dramatically.
Impacts of plastic pollution on marine life
The revolution of plastic in the fishing industry has fed billions, but left a paucity of life in the oceans and more suffering than we understand. A lost nylon fishing net or tangled mass of hook and line does not stop fishing, the results are horrifying and solutions hard won. Lost fishing gear, called ghost nets, are more costly than you might think — scientists studying the economics of subsidizing recovery of lost nets in Puget Sound reported that the fish and crabs that are caught and die in lost traps and nets was worth more than 12 times the cost of recovery programs.
Treat sofas like electronic waste, say scientists
Planet Earth Online
Waste from soft furnishings like curtains, cushions and sofas should be discarded with the same caution as electronics, say scientists.
Both types of waste contain brominated flame retardants, which have been shown to damage the environment and human health. In the U.K., at least two thirds of electronic waste – or e-waste – has to be treated before it can enter landfill. But furniture waste isn't currently regulated.
E-waste recycling programs of the Federal Government slammed by BAN
The Basel Action Network (BAN) opposes a claim made by the federal government that the government is “leading by example” in how it handles its own e-waste. The global toxic trade watchdog organization says the government continues to allow use of the weakest available recycling standard, which lets recyclers export the hazardous e-waste to developing countries. Such exported e-waste often winds up being processed “in dangerous back-yard operations” in China, West Africa and South Asia, BAN says.
Chemical used by Colgate Total toothpaste to fight off gum disease is linked to cancer
A chemical that has been linked to cancer cell growth is being used by millions of Americans in toothpaste every day.
The company behind Colgate Total insists that triclosan, which it uses to stave off gum disease, is safe to use because the toothpaste was approved in 1997 by the Food and Drug Administration.
But the toxicology documents used by the FDA to approve the toothpaste were only released early this year after a Freedom of Information Act lawsuit last year - and reveal the agency relied upon company-backed science to reach its conclusion, Bloomberg News reported.
Bioplastic created using rice starch
Finnish researchers have made a bioplastic from rice starch.
The new transparent, biodegradable material has a high degree of mechanical strength and good thermal resistance.
The bioplastic creation was reported by Virginia Nykänen and colleagues at Aalto University in their green chemistry paper entitled: “An Efficient and Stable Star-Shaped Plasticizer for Starch,” published July 10.
