I read in the latest National Geographic recently a short piece on the biodegradability of polystyrene and was immediatly suspicious. Sounds a lot like what you describe below - that it's still plastic. "Polystyrene, the petroleum-based plastic popular for use in disposable drinking cups, is rarely recycled and doesn't decompose. But scientists recently found a way to convert the stuff into something more ecologically friendly. After melting polystyrene into styrene oil, they feed it to a bacterium called Pseudomonas putida that is commonly found in soil. The resulting output from the bacteria is biodegradable plastic." Is National Geographic painting a misleading picture? Or are they talking about something different that what Mattew describes?
