Biodiesel Technologies

REG has spent the past two decades developing improved technology and processes in the biodiesel production process. We have approved patents, patent applications and trade secrets in the areas of transesterification, glycerolysis, esterification, feedstock pretreatment and cold filtration. These technologies enable REG to utilize a wide array of feedstock including animal fat, inedible corn oil, used cooking grease and vegetable oils to produce high-quality renewable fuel.
