Cornwall’s landfill is expected to remain in operation until 2047, six years longer than previously projected, thanks to new waste diversion measures launched in 2025. Council was informed on November 10 that the clear bag policy, green bin organics program, and biosolids diversion have made a significant impact, pushing the landfill’s projected closure from 2041 to 2047.
The curbside green bin program, introduced in January, is on track to divert approximately 4,620 tonnes of organic waste in its first year-an 81.1% capture rate. “That’s incredible,” said Councillor Carilyne Hébert. “To gain six years in just 10 months is outstanding. Clearly, people are doing their part.”
The clear bag policy became fully enforced in April, raising the organics diversion rate from 20.7% to 51.6%. Combined with previous steps like the 2-bag limit, alternative daily landfill cover using tarps, and increased tipping fees for the IC&I sector, Cornwall has steadily improved its residential diversion rate to a projected 62% this year.
Councillor Sarah Good noted the financial stakes: “From 2012 to now, we’ve gained almost 20 years on landfill closure. That’s saving the city millions. The estimated cost of closing the landfill is upwards of $50 million.”
Biosolids once dumped in the landfill are now processed into agricultural fertilizer at a third-party site, saving over $200,000 annually and preserving space for future use.
