The US Environmental Protection Agency (EPA) has granted Aemetis approval to produce ethanol using grain sorghum and biogas with the plant’s existing Combined Heat & Power (CHP) system to generate higher-value D5 Advanced Biofuels Renewable Identification Numbers (RINs). The EPA approval also includes D5 RIN generation for separated food waste feedstock used at the Keyes plant, allowing Aemetis to qualify its ethanol as Advanced Biofuels.
