The old Britannia Sanitary Landfill Site located in Mississauga was closed in 2002 and over its years of operation had received over 10 million tonnes of waste.

The Region of Peel wanted to reduce greenhouse gas emissions at the landfill and find a beneficial use for the landfill gas. As an added challenge to the project, the City of Mississauga operates the Britannia Hills Golf course on the final contours of the landfill. Integrated Gas Recovery Services provided the Region of Peel with a solution that addresses all of the challenges of this project with a proposal to utilise gas for the generation of electricity.

The wellfield is designed to avoid the fairways of the golf course while maximising the collection of landfill gas. Wells are strategically located in the driving range and along cart-paths as well as the perimeter of the site.

The electricity generation plant is located off-site from the landfill thus creating no impact on the golf course. Gas is delivered to the plant through a dedicated pipeline for a distance of 800 m. The generation plant comprises of three reciprocating engines and associated gas processing equipment with a total generation capacity of approximately 5.5 MW of power.

The electricity generated by the plant is termed “green” energy since it doesn’t rely on fossil fuels. In fact not only does this project displace traditional sources of electricity, it also ensures the destruction of 250,000 tonnes of CO2e (carbon dioxide equivalent) annually through the combustion of landfill gas, which would otherwise vent to the environment. All emission reduction credits belong to the Region of Peel who has also opted to purchase the green power generated by the plant for its own use. Ausenco Sandwell provided engineering of the utility building, the process piping, permitting and site plan approval.
