Converting manure to energy: project completed

Texas Water Resources Institute’s Assembly and Testing of an On-Farm Manure to Energy Conversion BMP for Animal Pollution Control project, which demonstrated the conversion of animal manure in a fluidized bed gasifier to produce heat and power, recently finished. The study concluded the conversion of animal manure was feasible and the eutectic point temperature of the manure ash was found to be around 600°C.

Converting manure to Energy Dr.s Cady Engler, Sergio Capereda, and Saqib Mukhtar in the Department of Biological and Agricultural Engineering at Texas A&M University were the principal investigators.

Excessive land application of manure from animal feeding operations has caused soil phosphorus levels to exceed the amounts needed for crop growth. The main goal of the project was to evaluate the feasibility of converting animal manure by thermal means to generate heat, fuel and power.

The study involved developing and assembling a portable On-Farm Manure to Energy Conversion System that can be used for on-site demonstrations to show alternative uses of manure and dairy waste effluent while producing energy that is beneficial to the producer.

Funding for the project, which started in 2008, was provided by the U.S. Department of Agriculture’s Natural Resources Conservation Service.
