Upcycling nutrients from poultry slaughterhouse solid waste into value-added bioproducts using black soldier fly larvae cultivation.

The objective of this work was to test the hypothesis that black soldier fly larvae (BSFL) can be grown successfully on dissolved air flotation solids from poultry slaughterhouses by blending it with food waste. Dissolved air floatation (DAF) solids generated from poultry slaughterhouse wastewaters have high water content (>70%) and the solids are rich in fats (50-60%) and proteins (20-30%) on a dry weight basis. BSFL bioconversion of fat-rich wastes has been a challenge in the past and, in the current work, we have tested the effects of blending DAF solids with post-consumer food waste at different substrate ratios (1:0, 1:0.

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

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.
