Soem examples of bioplastics
Experimental corn-based palstics have been around since the 1930s; Nylon 11, from castor beans still requires a great deal of heat and pressure and several toxic chemicals in processing, and when disposed of, is no more biodegradable than other plastics

The bacteria Ralstonia eutropha is a miniature bioplastic factory
The most abundant PHA is poly(3-hydroxy-butyrate) (PHB), which bacteria synthesize from acetyl-CoA. Growing on glucose, the bacterium Ralstonia eutropha can amass up to 85% of its dry weight in PHB, which makes this microorganism a miniature bioplastic factory. - Read More

Traditional polyethylene from sugarcane and ethanol
The recent announcements (2007) by The Dow Chemical Co. [www.plastics.dow.com ] and its Brazilian partner, Crystalsev [www.crystalsev.com.br ], and by Braskem [www.braskem.com.br ] in Brazil, that they can now make traditional polyethylene from the renewable resources of sugarcane and ethanol are exciting new developments in the area of biopolymers. - Read More

Definition of bioplastics and biopolymers
The definition of these terms is not exactly clear - whether they pertain to biodegradability, or whether they are based on renewable sources and so on...the Japanese have announced that they are going to require a twenty-five-percent renewable content based on weight for many of these materials to be called biopolymers. - Read More

E.coli can now help produce plastic
have announced that Escherichia coli (E. coli), a bacterium generally found in the gut, could be genetically engineered to produce 1,4-Butanediol (BDO). BDO is a monomer, or building block, which can be used to synthesize a variety of plastics, rubber and synthetic fibers. - Read More
