Production at the Ethanol Plant generates CO2 from the fermentation of corn. The facility partnered with a nearby tomato greenhouse facility to pipe excess CO2 into their greenhouse to boost tomato growth. They were also able to capture the waste heat from their grain drying process through a heat exchanger and through closed-loop piping underground to help heat the greenhouse. The result was bigger tomatoes and a reduction in energy costs by 40-50%. This was the first greenhouse facility in North America to be warmed by waste heat.
