An Ontario company has developed a way for farmers to turn their vegetable waste into heating fuel. The Great Lakes Radio Consortium’s Karen Kelly reports.


Southern Ontario is home to some of the largest greenhouses in North America. And they produce several tons of vegetable scraps every week. Most of it ends up in landfills, where it decomposes and produces heat that escapes into the atmosphere.
But engineers at Acrolab in Windsor, Ontario say they’ve found a way to capture that heat without using other energy sources. Acrolab makes copper heating pipes that are filled with fluid. When one part of the pipe is heated, the fluid instantly transfers the heat throughout the whole thing. Engineers placed these pipes in compost piles and then extended them into a test greenhouse. The pipes heated the greenhouse for five months. The company is now starting pilot projects in three different sized farm buildings.
They say it’s too early to estimate the cost. But they expect farmers will reduce their energy bills by 40 to 60 percent. For the Great Lakes Radio Consortium, I’m Karen Kelly.

Global Worming

Remember when you were a kid, how you’d spend hours poking around,
looking for creepy crawly things? If one woman has her way, a lot more
of us will rediscover that joy…And as adults, also appreciate some
practical benefits. The Great Lakes Radio Consortium’s Wendy Nelson
