Several California dairies are supplementing their revenue stream by investing in methane digesters. Neil Black, with CalBio says his company brings together digester development and dairy expertise to create successful digester projects that integrate with milking operations.
CalBio designs, develops, operates and finances digester projects. They help dairy operators with programs to sell the electricity or produce vehicle fuel with funding from the California Energy Commission, the California Department of Food and Agriculture and the San Joaquin Valley Air Pollution Control District. He says they have also utilized U.S. Treasury tax programs and USDA farm incentives.
