Biodiesel can be made from various plant oils and waste grease. It is primarily sold as B20, which is a blend of 20% biodiesel and 80% petroleum diesel. Blue Sun aims to produce biodiesel through an integrated process from growing oilseed crops to processing the crops into biodiesel. Their goal is to develop more productive oilseed crops to provide a sustainable and competitive advantage.
