Renewable Energy Group – headquartered in Ames, Iowa — has been a Wisconsin Clean Cities member since 2017.

The roots of Renewable Energy Group (REG) go back more than two decades to when the company operated under the umbrella of West Central Cooperative in Ralston, Iowa. The company’s history parallels that of the biodiesel industry as a whole. When they made their first batch of biodiesel in 1996, the industry was still in its early stages and was a niche market with a potential few foresaw. While REG’s leaders grew the company carefully and consistently by finding opportunity within challenges, they also advocated for the biodiesel industry as a whole, often working with competitors for the greater good.
