General Motors Canada completes major renewable landfill gas project

General Motors Canada (GM Canada) has completed a $28 million (€18 million) cogeneration investment at the GM St Catharines Propulsion Plant that will lower greenhouse gas (GHG) emissions and cut costs.

The cogeneration programme is expected to reduce GHG emissions by around 70% while protecting the engine and transmission plant from rising electricity and carbon costs.

The 6.4 MW cogeneration project uses renewable landfill gas delivered by pipeline from the near Walker landfill to generate electricity from newly installed engines at the plant. GM Canada will also recover the thermal energy that is typically considered waste to power and heat its St Catharines Propulsion Plant.

The project was developed in partnership with Alectra Utilities, Integrated Gas Recovery Services (IGRS) and the Ontario Centres of Excellence. It is the first complete renewable landfill gas industrial cogeneration system in Ontario delivering renewable landfill gas from an off-site source.

GM St Catharines plant director Carolyne Watts said: “This cogeneration project demonstrates the power of local partnerships to deliver results that improve the bottom line, protect the environment, and meet our sustainability targets.”

Geordie Walker, president and CEO of Walker Industries, commented: “Walker and IGRS are pleased to be providing long-term environmental solutions to local partners by utilising landfill gas as a renewable energy resource.

“We are committed to converting waste into a resource and contributing to a sustainable future.”

The firm has committed to powering all of its global operations’ electricity needs with 100% renewable energy by 2040.
