MASON CITY, Iowa -- October 28, 2013

Renewable Energy Group® (NASDAQ: REGI) held a ribbon cutting ceremony to
formally open their recently acquired biodiesel refinery in Mason City, Iowa
and announced it has begun a $20 million project to upgrade the plant to a
multi-feedstock facility.

REG completed the acquisition of the former Soy Energy, LLC refinery on July
31, 2013. REG immediately began efforts to repair and re-start the plant and
began producing biodiesel on October 1.

“REG Mason City fits into our existing network of biodiesel plants very well
and is an ideal location to bring in raw materials for biodiesel production,
is a good distribution point, and is sited well to serve our customers and
terminals,” said Daniel J. Oh, President and CEO of Renewable Energy Group,
Inc. “As we continue to grow as a company and an industry, we are dedicated to
our communities like Mason City, and providing America with advanced biofuel.”

Brad Albin, REG Vice President, Manufacturing told the crowd about the
upgrades the company will make. “With these upgrades, we will be able to
utilize lower cost raw materials  like inedible corn oil from ethanol
production, used cooking oil and animal fats, with the majority coming from a
close proximity to Mason City,” Albin said. “This will give REG Mason City the
ability to deliver the highest quality product available, in line with the REG
quality standards.”

REG now has eight active biorefineries in four states, with Mason City being
the company’s third Iowa facility, joining the company’s first refinery in
Ralston and a plant in Newton. The company also has a multi-feedstock
biorefinery in nearby Albert Lea, Minnesota, where a $21 million
multi-feedstock upgrade was just recently completed. REG also has two
refineries in both Illinois and Texas respectively. The REG-owned biodiesel
production fleet has an annual production capacity of 257 million gallons.

Renewable Energy Group® is a leading North American biodiesel producer with a
nationwide distribution and logistics system. Utilizing an integrated value
chain model, Renewable Energy Group is focused on converting natural fats,
oils and greases into advanced biofuels. With 257 million gallons of nameplate
annual production capacity at biorefineries across the country, REG is a
proven biodiesel partner in the distillate marketplace.

For more than a decade, REG has been a reliable supplier of biodiesel which
meets or exceeds ASTM quality specifications. We sell REG-9000® biodiesel to
distributors so Americans can have cleaner burning fuels that help lessen our
dependence on foreign oil. REG-9000® branded biodiesel is distributed in
nearly every state in the U.S.
