Thermal hydrolysis of poultry byproducts for the production of microbial media.

ABSTRACT: Rendered meat byproducts are important feedstocks for pet food formulas, esterified biodiesels and other bioproducts. However, feedstocks with high water contents are currently not attractive for rendering due to the need to evaporate the resulting high protein "stick" water. Consequently, many wet meat byproducts, like poultry dissolved air flotation (DAF) solids, are land applied, wasting a potential resource, and causing malodor for nearby communities. Herein, we present a process for rendering wet meat byproducts where the stick water produced from rendering hydrolyzers is sold as value-added microbial media and therefore does not require evaporation. Thermal hydrolysis experiments were performed on a wet (7% solids content) and drier feedstock (25% solids). Amino acids, the most valua
