216. Waffle cone factory shares its warmth
A German waffle cone factory is using its waste heat to heat the homes in its hometown—an ingenious initiative that could serve as a template for other heat-wasting small-town factories.

187. Truly Green Farms – Growing tomatoes with waste energy
A greenhouse in Ontario is using waste heat from the stack of an ethanol plant to grow tomatoes and that’s only the beginning of this amazing story of industrial symbiosis. Corn comes into the biorefinery and produces ethanol, industrial alcohol and corn oil and virtually all of the waste from the plant is also used as well in this virtuous cycle.
134. Biogas: Brown waste – green power!
Lethbridge Biogas takes the manure and food waste, mixes it together, heats it to 39 degrees Celsius and captures the methane to power twin 1.4-megawatt generators, producing enough power for 3,000 homes.
71. Industrial symbiosis: Growing tomatoes with an ethanol plants waste
We head to Chatham, Ontario to explore a unique example of industrial symbiosis between an ethanol plant and a greenhouse.
67. Harvest Power: Energy and compost from rotten food
Learn how Harvest Power turns your rotten banana peels and other gross assorted food waste into energy and compost at their site in Richmond, BC.
39. Nanaimo: Turning waste into compost, carbon credits and electricity
The Nanaimo Regional District is home to about 145,000 people on the east coast of Vancouver Island. This west-coast municipality is turning its trash into compost, clean energy and carbon credits.
36. Micro-brewed biodiesel powers bus tours in Victoria
The Cowichan Bio-Diesel Cooperative is the plucky little coop that could. In 2004 they started selling 20-litre jugs of bio-disel at the local farmer’s market. Nine years later they’re planning to produce 150,000 to 200,000 litres with a mix of corporate and retail clients.
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.
31. Biogas: Closing the loop on cow poop
Cow poop isn’t typically thought of as a valuable resource. But with a process called anaerobic digestion that cow poop can be turned into electricity, heat, a near odourless fertilizer and and animal bedding.
16. Pumpjack powerplants
Canadian Control Works is a small Edmonton based company with a big idea. They’ve figured out how to create green electricity from the downswing of a pumpjack with a device called the Enersaver. We don’t give them much thought but each pump jack is moving 5-10 tons each time it goes up and down. By harvesting that energy oilfield operators save money and stabilize the grid around it.
