(192b) Technology Advancements for Producing Biodiesel from Waste Lipids

Starting with the passage of the Renewable Fuel Standard (RFS) in 2005 and more recently a societal and customer demand for low carbon fuels, waste lipids have been an increasing source of raw material used for producing biomass based diesel. These feedstocks, such as used cooking oil and distillers corn oil from the ethanol industry, have presented new opportunities and processing challenges for biodiesel manufacturing. A case study will be presented to show how Renewable Energy Group developed the technology and capabilities to become a leader in utilizing these waste lipids, thereby supporting a circular economy.

Renewable Energy Group, Inc. (“REG”) is leading the energy and transportation industries’ transition to sustainability by converting renewable resources into high-quality, sustainable fuels. REG is an international producer of sustainable fuels that significantly lower greenhouse gas emissions to immediately reduce carbon impact. REG utilizes a global integrated procurement, distribution, and logistics network to operate 11 biorefineries in the U.S. and Europe. In 2020, REG produced 519 million gallons, or 1.7 million metric tons, of cleaner fuel delivering 4.2 million metric tons of carbon reduction. REG is helping to meet the growing global demand for lower-carbon fuels and leading the way to a more sustainable future.
