33. Landfill gas: How old garbage can generate electricity

Landfills are quickly becoming centres of innovation when it comes to turning what we throw away into energy. Edmonton has had a landfill gas operation since 1992 and it was the first in Western Canada to turn old garbage into a new resource. Learn how it’s done this week on Green Energy Futures.

Cows in the cow barn eat when they are hungry and big rakes automatically collect manure from the floors to feed the biogas operation on on the Callaghan family farm in Lindsay, Ontario. Ontario has built about 30 similar projects that produce electricity, clean up environmental problems and creates economic diversification on the farm. Photo David Dodge, GreenEnergyFutures.ca
