California-based Aemetis, Inc. has received US Environmental Protection Agency (EPA) approval for the issuance of D4 RINs upon the importation into the US of biodiesel produced from waste fats and oils (WFO). The EPA also approved the issuance of D6 RINs when biodiesel is produced using other feedstocks. Aemetis built and operates a 50 million gallon per year capacity distilled biodiesel production facility on the East Coast of India.
RINs are numerical codes created with every gallon of biofuel domestically produced or imported into the US. RINs play the dual role of a renewable fuel credit to incentivize renewable fuel use, and a tracking mechanism to monitor the production, movement and blending of biofuels. The D-code (D#) of a RIN identifies the renewable fuel standard category for a particular fuel based on its projected greenhouse gas reduction requirement.
EPA currently has five RIN D-codes (D3, D4, D5, D6 and D7). D3 and D7 are for cellulosic biofuels with a GHG reduction requirement of 60%; D6 is for renewable fuels such as corn ethanol (GHG reduction 20%) or butanol; D4 is for biomass-based diesel (50% GHG reduction); and D5 is for advanced biofuels, including sugarcane ethanol and biogas (50% GHG reduction).
In September 2013, EPA granted Aemetis approval to produce ethanol using grain sorghum and biogas at its converted corn ethanol plant to generate D5 Advanced Biofuels Renewable Identification Numbers (RINs). (Earlier post.)
Biodiesel produced at the Aemetis India plant (Universal Biofuels in Kakinada, India) also recently earned International Sustainability and Carbon Certification (ISCC) Category 2 certification (EU-ISCC-Cert-DE105-83032301).
With the recent construction and commissioning of a biodiesel distillation column at the India plant, the company is producing a colorless biodiesel with 99.5% esters and nearly no monoglycerides, water or other contaminants. Aemetis biodiesel has met and exceeds all D6751 biodiesel specifications, allowing for use in all diesel engines.
The India plant was built with the capability to separate oils for food and biodiesel applications. This flexible feedstock processing capability allows the plant to use multiple feedstocks at decreased costs.
Aemetis owns and operates a 60-million gallon capacity ethanol and 420,000 ton animal feed plant in California that is the first upgraded facility approved by the EPA to produce D5 Advanced Biofuels using the sorghum/biogas/CHP pathway. Aemetis also built, owns and operates a 50 million gallon capacity renewable chemicals and advanced fuels production facility on the East Coast of India producing high quality, distilled biodiesel and refined glycerin for customers in Europe and Asia. Aemetis operates a research and development laboratory at the Maryland Biotech Center, and holds five granted patents on its Z-microbe and related technology for the production of renewable fuels and biochemicals.
