Abstract
Waste disposal in the food processing industries is a major concern that includes bothenvironmental and capital issues. The objective of this project was to extract energy from FoodProcessing Byproducts (FPBs) by gasification. Gasification involves combustion of FPBs to generatea producer gas that can be used to produce energy or generate steam. Data from a value-addedmeat processor was used as a case study for evaluating the feasibility of this project. A smalllaboratory-scale gasifier was used to gasify the FPBs. The FPBs tested were dried sludge,dewatered sludge, inedible meat, flour breading (used on meat products), and wood pellets.Producer gas samples were collected and analyzed in the laboratory. The amount of energy in theproducer gas was compared with the higher heating value (HHV) of the FPBs to calculate the coldgas efficiency of the gasifier. Cold gas efficiency of the gasifier ranged from 47-70%. The cold gasefficiency was then used to identify the potential savings that could be obtained by gasifying theFPBs; about $0.77 Million/ year.
