Suez inks biomethane plant deal with City of Montreal, Canada

French waste management company Suez has signed a deal with the City of Montreal to create an organic waste treatment centre. The new plant will convert organic waste material into biomethane, providing enough renewable gas to power around 3,600 households.

The €115 million contract covers a two-year construction period followed by five years of operations. This is the second contract won by Suez in Montreal this year; the firm is currently building a composting facility in the city’s Saint-Laurent borough.

Suez will build the biomethanation centre with the capacity to process 60,000 tonnes of organic material annually. It will recover organic waste produced by nearly 1.5 million residents in Montreal’s east side and the city centre and convert it using anaerobic digestion.

It is hoped the plant will contribute to the city’s efforts to reduce greenhouse gas emissions. Currently, waste is taken to a facility around 50km northeast of Montreal; the new plant will reduce the distance travelled. The resulting biomethane produced at the plant will also be non-polluting and locally-produced, contributing to a cleaner environment.

“Our concern for the environment is a major reason why the City of Montreal wants to become a leader in the use of biogas,” said Valérie Plante, mayor of Montreal. “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.”

Bertrand Camus, CEO of Suez, added: “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 Montreal in its transition towards a new local, sustainable and low-carbon energy model.”

The facility is expected to be commissioned in 2022.
