ASERTTI Digester Performance PartnershipStandardizing Evaluations of Performance of Systems Used by Livestock Producers for Biogas Production and Utilization
Digester ProtocolsASERTTI and EPA have completed a Protocol for Quantifying and Reporting the Performance of Anaerobic Digestion Systems for Livestock Manures. The protocol was developed through a collaborative process that included expert input, state review, and public comment. The protocol may be accessed at the link below:

estimates that there are about 180 anaerobic digestion systems for
livestock manures either in operation or in some stage of planning or
construction in the United States. And each year millions of dollars are
invested by states, farmers, and the federal government. While many
digesters are demonstrating the technical difficulties experienced with
this technology in the early 1980s have been resolved, some challenges
remain. As a result, livestock producers remain reluctant to make the
significant financial investment needed because of uncertainty about
performance and cost. Under the ASERTTI-EPA Digester project,
participating members and EPA’s AgStar are working to achieve a
generally accepted methodology for assessing the performance and
financial viability of digesters, allowing livestock producers and
public and private investors to make fully informed decisions.
