Green Biologics Ltd, the UK-based company that makes specialty chemicals from agricultural waste and sugar cane, has started commercial shipments of bio-based n-butanol and acetone from its manufacturing facility in Little Falls, Minnesota (USA).
Traditional “green” plastics have their share of problems, whether it be a compostable food container with sides too flexible to a secure lid or a biodegradable bag that rips on its way to the compost bin. But a new and improved biodegradable polypropylene carbonate film—PPC—may have solve those problems.
A team of researchers, led by Nobel Prize-winning chemist John Polanyi, employed a combination of experiment and theory to discover that the position of the molecule on the catalytic surface is a key factor in determining the rate at which particular bonds break.
Producing fuels and chemicals from CO2 and light has long been a dream of Biotech, and Amsterdam-based Photanol is working on making it an industrial reality with engineered cyanobacteria. The following article is an interview with Ross Gordon, Director of Business Development, about Photanol’s strategy.
Researchers at the University of Pennsylvania have pioneered a process that could enable the efficient recycling of rare-earth metals, which are found in many high-tech devices. Mining and purifying rare-earth metals is not only expensive and labor-intensive, but takes a devastating toll on the environment. The current methods for recycling them are wasteful and inefficient. The paper focused on one pairing in particular which could enable scientists to recycle rare-earths from compact fluorescent light bulbs.
