Biomass Feasibility Project Final Report - Xcel Energy

Animal Processing
Byproducts of animal slaughter and meat processing. Specific animal processing wastes listed in
BioPET are:
Feedstocks include:
Feather Meal, Greases, Lard, Meat Meal and Tankage, Poultry Fat, Edible Tallows, and
Inedible Tallows
Animal processing residues are the smallest category of biomass in the state, with annual
production of approximately 23,000 billion BTU. Meal and tankage are almost half of that at
47%. Other contributors are greases (22%), inedible tallow (15%), edible tallow (8%), and waste
water treatment plant sludge (5%).
