Trash to gas plan promoted
Pipeline would go from Brady landfill to U of M
Boilers could burn the gas produced by the landfill to generate steam to heat the university or other large natural gas users, says a report to be presented to the infrastructure and public works committee for approval.
The city's administration is hailing the proposed gas capture program at the landfill as "the single most effective action the city can take to address the issue of climate change."
The Brady Road landfill is one of the largest single sources of greenhouse gases in Manitoba. Gas from landfills -- about half of which is methane -- is created when organic garbage decomposes.
"The estimated (greenhouse gas) reduction of 97,000 tonnes (annually produced at Brady Road landfill) represents more GHGs than all other city operations combined," the report says. "Moving ahead with this project would demonstrate strong leadership from the City of Winnipeg in dealing with climate change."
The public service will ask committee members for $150,000 to allow the city's water and waste department to obtain environmental approvals, review how the city could capture the gas and finalize a business case. The city will propose selling the landfill gas it captures. The city estimates the total capital cost of the project would be about $9 million.
Many cities in Canada and the United States have landfill gas capture programs.
In an already completed investigation of landfill gas opportunities, the city determined gas capture at Brady Road was "feasible." A gas capture system of extraction wells, piping and a flare blower could capture between 50 and 75 per cent of the landfill gas generated.
"The landfill gas would be drawn through a series of collection pipes to a central location and flared (burned) off," the report says. 'To enhance the environmental benefits of this project, the LFG could also be used to create electricity or heat buildings."
It was unclear Monday how councillors would greet the city's proposal.
"I haven't read it yet, so I can't tell you," said Charleswood Coun. Bill Clement, the committee's chairman.
