City of Toronto Advances RNG Projects

The City of Toronto, Ontario has begun installing the first of what could be four facilities to produce large quantities of renewable natural gas (RNG) from the collection and processing of residential source separated organics (SSO) and solid waste. The initial project will upgrade the more than 5 million cubic meters of biogas produced annually through anaerobic digestion of residential SSO at the recently expanded Dufferin Organics Processing Facility. Installation began in February 2019 and the first gas molecules are expected to flow by the end of this year or early in 2020.

Under consideration are three additional facilities. One would be installed to upgrade biogas from Toronto’s second and larger anaerobic digestion facility at a site known as Disco Road. The other two would upgrade landfill gas at solid waste sites — the active Green Lane Landfill, about two hours southwest of Toronto, and the Keele Valley Landfill, just north of the city, which was closed 20 years ago.
