Dairy Plus Program Awards $17M+ to 15 California Dairy Farm Projects to Reduce Methane Emissions

The projects are estimated to reduce greenhouse gas emissions by an annual total of 148,451 MTCO2e, the equivalent of removing about 32,600 cars from the road each year

The California Dairy Research Foundation (CDRF) and the Department of Food and Agriculture (CDFA) Office of Environmental Farming and Innovation have announced grants worth $17.97 million through the Dairy Plus Program to 15 California dairy farm projects combined with corresponding Alternative Manure Management Program (AMMP) and Dairy Digester Research and Development Program (DDRDP) projects. 

The Dairy Plus Program is an incentive program operating in collaboration with CDFA's AMMP and DDRDP programs, which incentivize projects to increase dry handling and storage of manure to reduce methane production or projects that capture methane through digesters. Additionally, the program practices can further improve nutrient management and water quality outcomes. 

The selected projects are comprised of vermifiltration (filtration of manure wastewater using worm beds), advanced solid separation assisted by flocculants (coagulation of fine manure solids for separation out of liquid), and weeping walls (non-mechanical separation of manure solids from water) to reduce methane production while improving management of nitrogen.

The Dairy Plus Program incentive funds will enable emerging technologies to reduce methane and improve groundwater protection to California dairies as full-scale projects. UC researchers will measure the practices to quantify emission reductions and improved water quality outcomes. 

2024 Dairy Plus program recipients are estimated to reduce greenhouse gas emissions by an annual total of 148,451 metric tons of carbon dioxide equivalents (MTCO2e), the equivalent of removing about 32,600 cars from the road each year. 

CDRF in collaboration with CDFA provides funding for the Dairy Plus Program, as part of a Partnerships for Climate-Smart Commodities grant awarded to CDRF by the U.S. Department of Agriculture.
