Animal waste poses one of America's most serious pollution problems, because the natural decomposition of livestock manures releases large quantities of pathogens, excess nutrients, and greenhouse gas methane, among other pollutants. To overcome this challenge, the objective of this project is to design and assess the technical and economic feasibility of an innovative anaerobic co-digestion process for the simultaneous treatment of dairy waste and poultry litter
To achieve the objective, the following tasks will be performed: 1) Design and develop an innovative anaerobic co-digestion process for the treatment of dairy waste and poultry manure; 2) Assess the technical feasibility of anaerobic co-digestion in lab-scale systems; and 3) Assess the economic feasibility of anaerobic co-digestion of dairy waste and poultry manure in local rural communities.
This innovative anaerobic co-digestion design will significantly enhance the treatment efficiency of animal waste and the production of biogas as a renewable energy. This will meet not only the need of livestock producers for a sustainable animal waste management strategy, but also the need of the public and society for improved environmental quality. Success of the project will be evaluated by achieving the following: A bench scale anaerobic co-digestion system with reliable and stable operation; identification of optimal operational conditions; increased digestion efficiency and biogas yield; and demonstration of economic feasibility.
