Ecological Waste Management
Waste
The Waste Management Service, formerly known as COGERNO, operates a landfill site located in Montagne-de-la-Croix, Rivière-Verte, dedicated to responsible solid waste management. In addition, we oversee various diversion programs, including recycling, tire recovery, appliance collection, and used mattress disposal. We are also committed to promoting education and awareness on waste reduction, both in schools and within the community.
Opening Hours
Monday to Thursday: 8:00 AM to 5:00 PM
Friday: 8:00 AM to 3:00 PM
Saturday (from May 10 to June 14 and from September 13 to October 18, inclusive): 8:00 AM to 12:00 PM
The landfill site is closed on statutory holidays.

Landfilling
Waste is disposed of in a landfill cell designed to prevent leachate from seeping into the soil and contaminating watercourses. It is constructed using a cover layer, two synthetic geomembranes, a geogrid, a geotextile, a leachate collection drainage system, and a layer of clay.
A cell measures 60 meters in width by 200 meters in length and can hold 100,000 tonnes of waste. Its construction cost is approximately $1,200,000.
Waste disposed of in the cell is mechanically compacted, allowing for storage of approximately 700 kg of waste per cubic meter. It is then covered with a layer of soil to reduce issues with vermin or rodents, fire hazards, and wind dispersion.
Leachate Treatment
Leachate is a liquid that forms when meltwater or rain infiltrates the waste. Its exact composition depends on the types of waste present in the cell. Our landfill site is equipped with a leachate treatment system, which directs the leachate from the landfill cell to the following treatment basins: aeration basin, retention basin, sand filters, and sedimentation basin.
Landfill Area for Construction Materials
This area is reserved for the landfilling of construction materials. These materials are inert, meaning they do not produce leachate. They include concrete, wood, insulation materials, and drywall.
Hazardous Material Collections
Why should I bring my hazardous materials to collection events instead of throwing them in the trash?
It is crucial to bring your hazardous materials to designated collection events rather than throwing them in the trash, as improper disposal can have serious consequences. Hazardous waste, such as chemicals, batteries, and certain household appliances, can cause fires at landfill sites. Hazardous materials that end up in landfills also create challenges for leachate treatment.
When these materials are mixed with regular waste, they can react with each other or with other substances, creating dangerous situations. A fire at a landfill not only endangers employees and infrastructure but can also have harmful effects on the environment and public health.
By bringing your hazardous materials to the appropriate collection events, you help ensure their safe and responsible management, protecting our community and environment. Together, we can make a difference by choosing the path of safety and sustainability!

Recycling
Our recycling program is now managed by Circular Materials, a non-profit organization committed to building an efficient and effective recycling system in New Brunswick.

Used Mattresses
The NWRSC sorts all used mattresses at its site and gives them a second life by sending them to companies that recover recyclable materials.
Feel free to bring your mattress to the landfill site to give it a second life.
Refrigerated Appliances
Electronic appliance recovery is carried out at the NWRSC landfill site with the goal of recycling all of their components.
Biogas
Biogas is the gas produced by the anaerobic decomposition (in the absence of oxygen) of organic matter—a fermentation process that occurs notably in landfills. Although it is composed of several gases in varying proportions, its main component is methane (CH₄) (about 50%), a greenhouse gas more than 20 times more harmful than CO₂.
By capturing the biogas (methane) released from landfills and converting it into energy, we take another step toward preserving the balance of the Earth.
The methane released from the Montagne-de-la-Croix landfill site in Rivière-Verte produces enough energy to supply electricity to over 250 homes. The heat generated by the generator is transferred to the main building, making it self-sufficient for heating throughout the year.
Methane (Biogas) Capture, Recovery, and Power Generation System
Since 2010, the Montagne-de-la-Croix sanitary landfill has been able to capture the biogas escaping from buried waste. Biogas capture occurs in several steps, through multiple wells drilled at strategic locations and several kilometers of underground piping. The wells are equipped with self-draining pumps and a mechanical system that draws the biogas to the generator, where it is then converted into energy.
The following photo shows our generator used on-site to convert biogas into energy. The landfill site generator is equipped with a JenBacher engine, producing up to 633 kWh of energy.
Biogas Recovery Well from a Landfill Cell
The NWRSC uses a biogas capture well installed in a landfill cell to recover gases generated by the decomposition of organic matter. This system primarily captures methane, a potent greenhouse gas, thereby helping to reduce our environmental footprint.
This process is part of our ongoing efforts to adopt sustainable practices. The captured biogas can then be safely treated or burned to minimize its environmental impact.
The photo below illustrates the different layers beneath the surface.
The pumps used for methane extraction are powered by solar energy. Thanks to this eco-friendly solution, we can efficiently capture biogas while reducing our reliance on traditional energy sources.
