This study estimates the potential energy available from livestock and poultry wastes in the northeastern United States for 1982, with projections for 1990. Anaerobic digestion of dairy cow, hog, and laying hen manures could have produced 16.9 billion cubic feet of methane gas in 1982, with little change for 1990. Direct burning of litter from broilers, turkeys, and pullets could have resulted in 8.9 trillion Btu's in 1982 and 10.3 trillion Btu's in 1990. The total potential farm value of biomass energy ranged from $166 to $255 million in 1982 and $289 million to $458 million in 1990.
