We had a good stretch there since the last green bin debacle but the peace may soon be interrupted.

A London composting plant responsible for receiving 25 per cent of Toronto's organic waste has been shut down for two months due to odour problems.

The city is asking its three other compost handlers to try to pick up the surplus, as well as anaerobic composter at Downsview. If the other outlets can't handle the excess, up to 4,000 tons of organic waste may have to go to landfills.

The city's general manager of Solid Waste Management Services, Geoff Rathbone, said the situation "Points out the importance of Council's recent decision to build a second new state-of-the-art compost facility in Etobicoke."

"Ultimately, this strategy will allow the City of Toronto to be self sufficient with processing capacity inside our boundaries," he said.
