City of Montreal awards contract to build, operate, and maintain a SSO Anaerobic Processing Facility

, , ,

The City of Montreal recently signed a contract with SUEZ to design, build, operate and maintain a source separated organics (SSO) waste treatment center. This contract, worth $167 million (Cdn.), provides for a two-year construction period of the plant followed by a five-year operating period. This is the second contract won this year by SUEZ in Montreal, which is currently building a composting facility. The new plant will convert organic material into biomethane, producing enough renewable gas to power around 3,600 households.

SUEZ will build an organic waste biomethanation center that can process 60,000 tons of organic material each year, on the east side of Montreal Island. This plant will recover organic waste produced by nearly 1.5 million inhabitants of the east side and the city center into biomethane. SUEZ will equip the plant with innovative technologies allowing for the anaerobic digestion of organic material to generate biogas, which will then be purified using high-performance membranes to produce biomethane. Expected to be commissioned in 2022, the facility will be operated and maintained by SUEZ for a period of five years.

This plant will contribute to the City of Montreal’s efforts to reduce greenhouse gas emissions. First, it will significantly reduce the distances traveled in treating this waste, which is currently taken to a facility around 50 kilometers (31 miles) northeast of Montreal. Moreover, the new plant will convert the organic material into biomethane, a renewable energy that offers the same advantages as natural gas. Non-polluting and locally produced, the biomethane will be injected into the local gas network.

This facility is the second organic waste treatment centers planned by the City of Montreal to recover and divert away its organic waste from landfills by 2020. In April 2019, SUEZ was selected by the City of Montreal to design, build and operate the city’s first organic waste treatment center, located in the Saint-Laurent borough.
