The power of poop: Ottawa looks at turning dog waste into energy

It's a sightdog ownersknow well:garbage cans in parks piled high with plastic bags full of poop.

It's a lot of trash, and as dog ownership increases, so will the amount of wasteproduced by ourfurry four-legged friends.

But there's technology that can turn your dog's excrement into a valuable commodity and the City of Ottawa is looking into it.

Waterloo already on board

For the pastyear, Waterloo, Ont.,has been testing a programthat turns dog waste into energyusing a process called anaerobic digestion, whichhappens when organic waste breaks down in an oxygen-free environment.

The process creates abiogas which is produced at aplant in Elmira, Ont. that can beburned for heat and energy. Anyleftover waste isused for fertilizer.

A number of cities are following Waterloo's lead, and Ottawa could also be on board.

Acity official said staff have been talking to acompanycalled Suteraand arelooking at the implications of creating a similar program.

"City staff have had conversations with Sutera regarding their pilot programs in other municipalities across Ontario," wroteLaila Gibbons, Ottawa's director of parks, forestry and stormwater services, in a statement.

"Staff will be contacting these municipalities once they have gained some experience with this system in order to get a better understanding of the benefits that the program may offer and how they are managing the disposal of the dog waste if they do not have access to a bio-digester facility as they do in Elmira," Gibbons added.

Mississauga's poop pilot project

Christopher Pyke, a wastediversion supervisor in Mississauga, Ont., will be installing waste receptacles for dog poop across his city as part of a pilot project.

He told CBC Radio's Ottawa MorningThursday that people using city parks are frequently stuffingdog poop into recycling bins, forcing the city to take the contaminated recycling tolandfills instead.

"So all of the recycling that was being done in our parks was contaminated and was kind of destined to go to the garbage as opposed to being recycled, as we were trying to do," he said.

"That's a big problem for us."

As for the plastic poop bags, Pyke said thematerial gets ground up and separated from the poop as part of the biogas production process.

Mississauga plans to install 14 in-ground waste containers in eight city parks at a costof $90,000 and hopes to collect 60 metric tonnes of dog waste in ayear.
