SUEZ wins contract for second organic waste treatment plant in Montreal

In Canada, global waste and water management company SUEZ Groupe SAS (SUEZ) has announced that the City of Montréal has signed a contract with SUEZ to design, build, operate and maintain an organic waste treatment center. This contract, worth around EUR 115 million, provides for a two-year construction period of the plant followed by a five-year operating period.

In Canada, the City of Montréal has signed a contract with SUEZ to design, build, operate and maintain an organic waste treatment center that will convert organic waste into biomethane for injection into the gas grid. This contract, worth around EUR 115 million, provides for a two-year construction period of the plant followed by a five-year operating period and is the second such project for SUEZ in Montreal.

According to a statement, 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 natural gas (RNG) to power around 3 600 households.

SUEZ will build an organic waste to biomethane center that can process 60 000 tonnes 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 (AD) 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 Montréal’s efforts to reduce greenhouse gas (GHG) emissions. First, it will significantly reduce the distances travelled in treating this waste, which is currently taken to a facility around 50 km (31 miles) northeast of Montreal.

Moreover, the new plant will convert the organic material into biomethane, which is a renewable energy source that offers the same advantages as natural gas but with a lower carbon footprint. Non-polluting and locally produced, the biomethane will be injected into the local gas network.

Our concern for the environment is a major reason why the City of Montréal wants to become a leader in the use of biogas. Biogas plants significantly curb the greenhouse effect by capturing this harmful gas and using it as fuel. Biogas generation helps cut reliance on the use of fossil fuels, such as oil and coal, said Valerie Plante, Mayor of Montreal.

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

Recovering household waste into new resources is as much an economic issue as an environmental one: it helps preserve natural resources, curb greenhouse gas emissions and reduce the volumes of waste stored. Cities like Montreal are now playing a key role in the circular economy by creating local recovery cycles. SUEZ is proud to support the City of Montréal in its transition towards a new local, sustainable, and low-carbon energy model said Bertrand Camus, CEO of SUEZ.
