US biomass-based diesel production production in October passed the federal mandate for full-year 2013, Environmental Protection Agency data showed Monday. Production through October was at 1.39 billion gallons, besting the Renewable Fuels Standard’s 1.28 billion-gallon target for the year. The remaining production throughout 2013 can be partially applied to this year’s ethanol mandate or advanced biofuel mandate, and to 2014’s mandates. Monthly biodiesel production was lower in October for just the third time in a record-breaking 2013, down 3.34 million gallons to 163.78 million gallons. US biomass-based diesel production has been spurred through the year by the return of the $1/gal biodiesel blending tax credit and a 10 cents/gal credit for agricultural biodiesel producers.
