Ethanol plant to supply CO2, waste heat to greenhouse

By Staff | February 14, 2013

A 195 MMly ethanol plant in Chatham, Ontario, will supply waste heat and carbon dioxide to an adjacent greenhouse under development by Truly Green. Greenfield Ethanol-Chatham plant is updating its technology to condense stack heat through a series of exchanger systems, allowing the ethanol plant to supply hot water to the greenhouse. The water will be returned to the ethanol plant through an expanding cooling water loop.

The project received a $3.2 million grant from Ontario’s Ministry of Agriculture, Food and Rural Affairs. The funding is being used to offset the cost of engineering and specialized equipment. Construction of the greenhouse will be completed in four phases. Once complete, it will cover a total of 90 acres sitting on 120 acres of land.
