Animal wastes are an environmental problem, particularly in feed lot areas where animals are concentrated. If the wastes could be upgraded to a fuel and burned in efficient small-scale engines, high value electric power could be produced, while mitigating environmental problems. This project will develop a small-scale power generation method to pretreat and combust the animal waste, so that reliable and low cost electric power can be generated using existing engines. Preliminary economic analyses have shown that the concept will be competitive in geographical areas of interest. In Phase I, opportunities for power generation from animal waste were identified and concept designs were prepared to address those opportunities. In addition, available test equipment was utilized to fill in key data gaps. Test results were then used to update the concept design and, with the support of manufacturers, an economic analysis was performed to show feasibility. In Phase II, a proof-of-concept system will be constructed and installed at an operating farm where the system will be tested. Test results will then be combined with economic analysis to evaluate the viability of the concept for commercial applications.

Commercial Applications and Other Benefits as described by the awardee: The concept should allow for the generation of electric power from animal wastes, primarily in remote rural areas in the U.S. and abroad. Potentially over 34 million tons of animal wastes could be beneficially used, thereby reducing surface and ground water environmental problems. Also the burning of this renewable waste could reduce CO₂ greenhouse gas emissions by over 30 million tons.
