Abstract: The present invention describes a method for production of a class of renewable specialty chemicals that may be used for a variety of purposes including as a solvent in the semiconductor industry and as a reagent for commercial chemical production. The precursor compound, PHA, can be produced using various feedstocks such as waste water treatment plant biosolids, distiller's grains and agricultural residual biomass (e.g., corn stover and rice straw). The production of specialty chemicals in tandem with energy production can serve to aid the overall economics of renewable feedstock energy production.

Abstract: The present invention describes a method for production of a renewable, combustible liquid fuel that may be used; in internal combustion engines, as a fuel source for electricity generation including turbines and fuel cells, or as a burnable heat source. This fuel is derived from set of biomolecules that are produced under nutrient limitation conditions as those found at a waste water treatment plant. More specifically this invention envisions the use of poly(3-hydroxyalkanoates) (PHA), especially those with monomeric residues ranging in size from C4 to C10, as a feed stream for production of a biofuel.

Abstract: The present invention relates to the use of a naturally occurring group of biological compounds to produce a combustible fuel that may be used in either internal combustion engines or as a burnable heat source. These compounds are a set of biomolecules produced by some bacteria in nutrient limiting environmental conditions when storage of carbon is necessary. More specifically this invention envisions the use of polyhydroxy alkanoates (PHA), especially those ranging in size from C4 to C8, to produce the combustible fuel.
