Expanding the Ridge Landfill isn't the only future project Progressive Waste Solutions has planned for the site.
The company is currently working on plans to develop a biogas facility to convert landfill gas into pipeline-quality natural gas, said Wes Muir, PWS director of public and government relations.
He said the local project would be about the same size as the biogas facility Progressive operates at its Lachenaie Landfill in eastern Montreal, which is the largest of its kind in Canada and among the largest in North America.
The biogas it taken from that landfill and turned into a “pipeline quality gas and put directly into pipelines and sent to customers in the United States,” Muir said.
According to the Renewable Energy From Waste magazine, the $44-million Lachenaie project, which began operations in March, is designed to process 10,000 cubic feet per minute of incoming landfill gas. The gas generated is equivalent to fuelling 1,500 trucks for 20 years and will result in the avoidance of greenhouse gas emissions of 1.2 million metric tons of carbon dioxide over a 10-year period.
Muir said the technology to convert landfill gas into electricity or pipeline-quality natural gas has been around for nearly 40 years and has been introduced to several landfills across North America.
