Incorporating sustainable practices can result in multiple
benefits. For example, at the Simplot Grand Forks potato
processing plant, we constructed an anaerobic digester as
part of a wastewater treatment upgrade project. Besides
achieving cleaner water, the biogas (methane) generated
by this treatment unit from the decomposition of potato
waste produces an energy source that lowers the plant’s
natural gas consumption by 25 percent.

Digester Facts
To fill the
digester with

would take
YEARS!
The plant has
the potential to
produce enough
methane daily
to heat
4,200
U.S. homes
for the day!
Wastewater and
potato trim from this
facility produces over
300,000 million Btus
per year of biogas!
