What is Biodiesel? – Biodiesel is defined as a fuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats that meets the fuel specification requirements of ASTM D6751. Produced in free-standing refining facilities.

What is Renewable Diesel? – Renewable Diesel is defined in the Internal Revenue Code (IRC) as liquid fuel produced from biomass that meets the fuel specification requirements of ASTM D975 (petroleum diesel fuel) or ASTM D396 (home heating oil). Produced in free-standing facilities.

What is Co-Processed Renewable Diesel? – Co-Processed Renewable Diesel is defined as Renewable diesel that is produced when an oil company adds small amounts vegetable oils or animal fats to the traditional petroleum refining process when producing diesel fuel (co- processing). This fuel is produced in existing oil refineries. There are subtle as well as obvious differences between these fuels and the benefits and drawbacks they represent to our environment and communities.
