EFI's 32-year track record includes media coverage from National Hog Farmer, IFAI publications, Santee Cooper utility media events, and industry press conferences. This timeline shows how the company's story has evolved alongside the biogas industry.
The largest US meat processors are deploying covered lagoon systems at scale to capture methane from wastewater lagoons. EFI's work with JBS, Tyson, Pilgrims, and Darling across dozens of facilities shows how the food processing sector is approaching biogas.
A 200-cow dairy cannot justify the verification costs of carbon credit programs alone. But cluster 10-15 small dairies in a geographic region and the economics change entirely. EFI's Columbus Carbon Cluster analysis shows how aggregation opens the market.
