COMPANY DESCRIPTION


California Bioenergy LLC (CalBio), founded in 2006, is one of the nationโ€™s leading developers, owners, and operators of dairy digester projects. Working closely with our family dairy partners and agencies, including CARB, CDFA, CPUC, CEC, and the EPA, alongside affiliates Midwest Bioenergy, Northwest Bioenergy, and Southwest Bioenergy, we capture methane, a potent greenhouse gas, and beneficially use it to generate renewable natural gas (RNG) and electricity. Our projects reduce more than 1 million metric tons of COโ‚‚e emissions per year, with a pathway to doubling these reductions over the next three years. A major use of CalBio RNG is as vehicle fuel; when truck fleets transition from diesel to natural gas, pollution emissions can drop by ~90%, delivering immediate air-quality benefits in communities such as Californiaโ€™s San Joaquin Valley and the L.A. Basin. These projects also help protect local air and water quality, create jobs, and provide new revenue and other meaningful benefits for our dairy partners.
