Microscopic Manufacturers Produce Eco-friendly Plastics

Last year's energy crisis highlighted an unforseen by-product of the looming fuel shortages of the 21st century. Petroleum-based products such as plastics that society takes for granted but now requires to function will run out with the oil. Scientists are looking to microorganisms to pick up the slack and help produce environmentally friendly plastics, according to research presented May 19 at the 109th General Meeting of the American Society for Microbiology.

"Organic waste from agriculture, industries and households forms a very large resource that is currently discarded or at best transformed into biogas. From a sustainability point of view it is desired to convert these organic resources in chemicals," says Mark van Loosdrecht of Delft University of Technology in the Netherlands, who has been working on using bacteria to transform this waste into bioplastics known as polyhydroxyalkanoates (PHAs).
