A system and method for converting organic wastes to biodegradable thermoplastic materials including polyhydroxyalkanoates is disclosed, which method includes treating the organic wastes with an acidogenic microbial population to form fermentative organic acids, and polymerization of the organic acids by PHA-producing microbial species to form PHAs. The system includes a first compartment for acidogenesis of organic wastes without oxygen, and a second compartment, for polymer synthesis by enriched cultures of species with oxygen such as R. eutropha, P. o...
What is claimed is: 1. A method of converting organic wastes to biodegradable thermoplastic materials including polyhydroxyalkanoates (PHAs) which comprises: (a) treating the organic wastes with an acidogenic microbial population in a first compartment to form volatile organic acids; and (b) polymerizing the volatile organic acids by polyhyciroxyalkanoate (PHA) producing microbial species in a second compartment to form PHAs, wherein the volatile organic acids are transferred from the first to the second compartments via molecule diffusion across barrie...
