July 25, 2021. The City of Toronto, Canada, will begin producing renewable natural gas (RNG) from Green Bin organic waste in the coming weeks. As per the strategy approved by City Council, the RNG will be blended with the natural gas that the City buys to create a low-carbon fuel blend that will be used to power City vehicles and heat City-owned facilities, allowing for greenhouse gas emission reductions across the organization.
The City, working with Enbridge Gas Inc., has installed infrastructure at the Dufferin Solid Waste Management Facility that will allow it to RNG from Green Bin organics. The new equipment will enable the City to take the raw biogas produced from processing Green Bin organics, turn it into RNG and inject it into the natural gas grid for City use.
As per the strategy that was approved by City Council last year, the RNG produced will be blended with the natural gas that the City buys to create a low-carbon fuel blend that will be used across the organization to power vehicles and heat City-owned facilities, allowing for a reduction in greenhouse gas emissions Citywide. The City will not start using the gas until the beginning of 2022 to ensure production capacity has stabilized. Until then, the gas will be stored in the grid.
The City has also identified potential biogas/landfill gas upgrading opportunities at several other City waste facilities including the Disco Road Solid Waste Management Facility, Green Lane Landfill, and Keele Valley Landfill. All four sites combined would have the potential to produce enough gas to fulfill the City’s entire natural gas needs annually (excluding City Agency, Boards and Commissions).
The next facility to receive RNG infrastructure will be the Disco Road Solid Waste Management Facility, with plans to have this site up and running by the end of 2023.
