CDFA’s Dairy Digester Research and Development Program (DDRDP) provides financial assistance for the installation of dairy digesters in California, which will result in reduced greenhouse gas emissions.
Dairy digesters are a renewable technology that uses livestock manure to produce methane, which is a renewable source of electrical energy generation and transportation fuel. The technology has many environmental and social benefits. More information on dairy digesters can be found on the CalEPA Dairy Digesters webpage and the USEPA AgSTARAnaerobic Digestion webpage.
CDFA receives funding from California Climate Investments for methane emissions reductions from dairy and livestock operations.
If you have questions about CDFA’s dairy digester research and development and dairy methane reduction programs, please email cdfa.oefi_ddrdp_tech@cdfa.ca.gov.
