REG Bio-Residual™ Oil

A new sustainable solution for generating heat or power, or for use in other industrial applications.

As the nation’s largest producer of biodiesel, Chevron Renewable Energy Group offers a consistent supply of high-performing bio-residual oil for use as a clean-burning alternative to traditional fuel oils.

High Performance to Meet Your Specifications

REG BioResidual Oil — a co-product of the biodiesel refining process — offers exceptional BTU performance when burned for heat or power generation. Whether used as a straight replacement for fuel oil, sprayed onto a traditional fuel source or blended with conventional heating oils, REG Bio-Residual Oil provides up to 128,000 BTUs per gallon while reducing emissions.

REG Bio-Residual Oil is an exceptional and renewable alternative to fuel oil, coal, natural gas and even other biomass fuel sources, providing many valuable benefits:

Better BTU performance

  • REG Bio-Residual Oil provides up to 128,000 BTUs per gallon.
  • Advanced production technology means REG Bio-Residual Oil contains minimal amounts of water or methanol.
  • REG Bio-Residual Oil offers a higher BTU value than coal or wood-fiber material, with approximately 100–125% more energy per pound than wood chips or pellets.

Cleaner burning

  • As a co-product of biodiesel production, REG Bio-Residual Oil has minimal carbon intensity.
  • REG Bio-Residual Oil burns cleanly and produces less particulate matter than other fuel sources. For example, ash content is reduced to 0.01-0.05% compared to 0.20% for No. 6 fuel oil.


  • REG Bio-Residual Oil is produced from recycled fats and oils such as used cooking oil, inedible corn oil, animal fat and other vegetable oils — renewable and plentiful resources. It is an affordable way to meet your company’s sustainability goals.
  • Fuel quality is guaranteed, regardless of feedstock.
  • In certain areas of the country, REG Bio-Residual Oil may qualify for Renewable Energy Certificates (RECs) and RINs, depending on the usage. 

Volume and Logistics to Meet Your Demands

REG Bio-Residual Oil is flexible and readily available. This high-viscosity product is liquid at room temperature. If your operation is equipped to burn a heavy fuel oil, it requires no infrastructure changes or special storage needs. If you burn solid fuel, take advantage of enhanced BTU performance by applying REG Bio-Residual Oil to your fuel source.
