Protocol for Quantifying and Reporting the Performance of Anaerobic Digestion Systems for Livestock Manures
A new Protocol (PDF, 33 pp., 239 KB, About PDF) has been issued for use by livestock producers, state agencies, project developers and others involved in developing farm scale anaerobic digestion systems. This Protocol will help standardize the process used to evaluate the performance of anaerobic digestion systems used to produce and capture methane (biogas) emissions from livestock manure. Producing and capturing methane in this way gives livestock producers the opportunity to use captured biogas to generate electricity and heat for on-site use, delivery to a local electric utility, or both.
Use of the Protocol will help increase the use of biogas, and prevent the release of methane into the atmosphere. The Protocol:
- describes information needed for performance evaluations and background information;
- describes acceptable methods for data collection regarding waste stabilization, biogas production, and utilization; and
- establishes a uniform approach for evaluating a project's economic viability and operational reliability.
Use of this Protocol will provide reliable, standardized information to system developers, customers and the investment community.
This Protocol was developed jointly by the U.S. EPA AgSTAR Program, the Association of State Energy Research and Technology Transfer Institutions (ASERTTI), and the U.S. Department of Agriculture. A number of public and private sector experts - representing digester technology developers, university biological engineering departments, state energy programs, and electric utilities - also contributed to the protocol.
