Certified Refuel™ is a mark signifying that a particular batch of fuel, or a petroleum company’s quarterly production, has met or exceeded the Renewable Fuel Standard.The Certified Refuel™ process is administered on the RINSTAR™ Renewable Fuel Registry, an independent registry which tracks renewable fuel from the point of production to its final blending into finished gasoline.Participants on the registry voluntarily submit their fuel to be specifically identified and tested for conformity with applicable environmental regulations.Purchasers of renewable fuels having the Certified Refuel™ designation have the confidence of knowing that the supplier of this fuel is providing a product that has met or exceeded the EPA standard for renewable fuel.
