Processing

Scalable. Practical. Renewable.

Fuel-grade biodiesel is produced from any fat- or plant-based oil to strict industry specifications (American Society for Testing and Materials/ASTM D6751) through a refinery process called transesterification. This established process combines natural feedstocks such as vegetable oils or animal fats with a short chain alcohol in the presence of a catalyst.

Raw vegetable oil cannot meet biodiesel fuel specifications, nor is it legally registered with the Environmental Protection Agency as a permissible motor fuel for sale and distribution.

Green Earth Fuels' biodiesel facilities utilize a flexible, hybrid-batch operating mode of reaction and employ the rigorous quality standards and processes necessary to conform to both ASTM-D6751 and BQ9000 biodiesel specifications.

Exceptional product quality

The Green Earth Fuels facility in Houston utilizes a proprietary design which focuses on producing ratable and high quality biodiesel that consistently meets stringent ASTM specifications.

A $100,000 on-site fuel-testing lab, managed by highly experienced Green Earth technicians, closely monitors biodiesel quality throughout every step of processing to ensure that all of the product will meet ASTM requirements before third-party certifications are performed, and that only high quality biodiesel is allowed to exit the plant.

Green Earth Fuels is also invested in ongoing feedstock development and best practices farming of current crops, to ensure a reliable supply of feedstocks that promote long-term environmental and economic sustainability.

A cleaner, safer alternative

  • Biodiesel is an environmentally friendly, low vapor pressure, non-toxic fuel.
  • Process is a simple chemical conversion of vegetable oils into a non-hazardous methyl ester.
  • All reactants are carefully controlled, recycled and reused in the production process.
  • The closed loop processing system minimizes emissions and waste streams.
  • The biodiesel production process does not create odor, noise or other public nuisances.
