Geoff Rathbone, former General Manager for the City of Toronto Solid Waste program, tells us how Toronto, a city of nearly one million people, managed to get 90% participation in source separation of the municipal waste stream. How the City Council was convinced to adopt one of the most comprehensive and innovative systems in the world. Who pays and how? Large producers of unsorted trash going to landfill pay the price for not sorting the trash. The folks and small businesses enjoy the benefit. Biogas generated from the composted organic remains is enough to power the fleet of trucks required to pick it up curbside. What goes in and what stays out? Kitty Litter and diapers too, it's not just food scraps going into the green bin.
