Of these operational projects, 126 generate electrical or thermal energy from the captured biogas. The electricity projects produce about 323,000 MWh annually, and boiler projects, pipeline injection, and other energy projects generate an additional 55,500 MWh equivalent per year. Other projects flare the captured gas to reduce methane emissions and control odor.

In total, the combustion of biogas at the digesters prevents the direct emission of about 38,600 metric tons of methane annually (811,000 metric tons of CO2 equivalent). In addition, the combustion of biogas displaces the use of fossil fuels for energy generation, thus achieving additional emissions reductions of greenhouse gases and other air pollutants.

Many of the operational, planned and under construction digester systems included in the database were funded in part by USDA Rural Development through the 2002 and 2008 Farm Bills.

These data were compiled from a variety of sources. AgSTAR cannot guarantee the accuracy of these data. AgSTAR encourages farm operators, project developers, financers, and others involved in the development of farm digester projects to provide updates and corrections to these data by contacting AgSTAR.
