Chemists redesign biological PHAs, 'dream' biodegradable plastics      (via sciencedaily.com)     Original source 

They've been called 'dream' plastics: polyhydroxyalkanoates, or PHAs. Already the basis of a fledgling industry, they're a class of polymers naturally created by living microorganisms, or synthetically produced from biorenewable feedstocks. They're biodegradable in the ambient environment, including oceans and soil.
