Green Chemistry News
Recent chemical reform bills call for green chemistry to be a core element as a source of safer alternatives. But green chemistry offers much more than just replacements.
Dozens of companies, as well as many academic laboratories, are pursuing the same goal — to produce algae as a source of, literally, green energy. And many of them are using genetic engineering or other biological techniques, like chemically induced mutations, to improve how algae functions.
Overshadowed by the angst over Assembly Bill 32 and its greenhouse-gas reduction mandate is a potentially more far-reaching legacy of Gov. Arnold Schwarzenegger’s administration: green chemistry to regulate toxic substances in consumer products.
There is an increasing awareness that cities function as complex, dynamic urban ecosystems. Thus major shifts in planning, decision making and implementation will be needed to address the challenge of urban sustainability.
Biodegradable biopolymer microspheres could deliver stem cells to the eyes of patients whose sight has been destroyed by age-related macular degeneration (AMD) to repair the damage and enable them to see clearly again, say researchers in the UK.
Nanotech discovery may green chemical manufacturing

McGill University researcher develops eco-friendly nanocatalyst
A new nanotech catalyst developed by McGill University Chemists Chao-Jun Li, Audrey Moores and their colleagues offers industry an opportunity to reduce the use of expensive and toxic heavy metals. Catalysts are substances used to facilitate and drive chemical reactions. Although chemists have long been aware of the ecological and economic impact of traditional chemical catalysts and do attempt to reuse their materials, it is generally difficult to separate the catalyzing chemicals from the finished product. The team’s discovery does away with this chemical process altogether.
