Sault Ste. Marie’s landfill has approximately two and a half years of remaining capacity, prompting city council to consider a $95 million plan that includes a $39.4 million expansion of the existing site and a $56 million biosolids treatment plant. Public consultations on the proposal are now underway.
Landfill Expansion Details
The $39.4 million expansion would extend the landfill’s lifespan by adding new cells and improving waste management infrastructure. City officials say the project is critical to avoid a waste crisis as the current site approaches its capacity limit.
Biosolids Plant Investment
In addition to the landfill expansion, the city plans to invest $56 million in a biosolids plant to treat sewage sludge. This facility would process organic waste and reduce the volume of material sent to the landfill, aligning with environmental sustainability goals.
According to city staff, the combined projects are essential for managing the municipality’s waste over the next two decades. Council members are reviewing the proposal and seeking public input before making a final decision.
Public Consultation Process
City council has launched a series of public consultation sessions to gather feedback from residents and stakeholders. The consultations will cover the environmental impact, cost implications, and long-term benefits of the plan.
“We need to hear from the community to ensure we make the best decision for Sault Ste. Marie’s future,” said a city spokesperson. “The landfill is nearing capacity, and we must act now to secure sustainable waste management solutions.”
Timeline and Next Steps
The city aims to finalize the plan within the next six months, with construction potentially beginning in 2027. If approved, the landfill expansion would add 15 to 20 years of capacity, while the biosolids plant would reduce organic waste by up to 30%.
Residents can submit comments online or attend upcoming town hall meetings scheduled for August 2026. The council is expected to vote on the proposal by late 2026.
