Greg Devries of Truly Green points out the greenhouse irrigation system for vine tomatoes that are grown in a large 22.5 acre greenhouse that will soon be heated by waste heat and fed waste carbon dioxide from the Greenfield ethanol plant in Chatham, Onta
Green Energy Futures:
By using waste heat from an ethanol plant and storing waste CO2 in tomatoes, Greg Devries says Truly Green will produce red tomatoes that are environmentally green.

Greg Devries of Truly Green greenhouse holds the pipe that will carry CO2 from the Greenfield ethanol plant to be fed to tomatoes in the greenhouse starting next year.
Green Energy Futures:
Greg Devries checks the tomato plants that will produce 5-7 times more tomatoes in the greenhouse compared to the field.
Green Energy Futures:
Truly Green Farms plans to heat more than 60 acres of greenhouse using the waste heat from the smoke stack across the road at Greenfield Specialty Alcohols.

Green Energy Futures:
Once constructed each Truly Green 22.5 acre greenhouse will employ 50 people.
Green Energy Futures:
Greg Devries says Truly Green hopes to produce 260 metric tons of tomatoes per acre of greenhouse, which is 7-8 times more production than you could achieve in a field.
