Mission

The sustainable processing of agricultural byproducts is one of the most significant challenges facing farming and food processing operations. At AgLand Renewables, a California subsidiary of CleanBay Renewables, we believe our process to convert poultry litter into renewable natural gas (RNG) and organic fertilizer will protect the environment, provide an economic boost to local communities and deliver renewable power and gas you can count on.
