Recovering Resources. Powering Tomorrow.
Every day, valuable energy is hidden within the materials we recover. From landfill gas and source-separated organics to fats, oils, grease and recovered wood fibre, Walker transforms waste streams into renewable energy that powers homes, businesses and industry while reducing greenhouse gas emissions.
Through innovative technologies and decades of resource recovery expertise, we help municipalities and businesses unlock the full value of materials that would otherwise be wasted – creating cleaner energy, reducing reliance on fossil fuels and supporting Canada’s transition to a lower-carbon future.
Our Renewable Energy Solutions
Landfill Gas Recovery
We recognize the opportunity for landfills to recover a significant energy resource. That’s why we capture landfill gas to use and convert it into renewable electricity, renewable natural gas (RNG), and renewable thermal energy, reducing methane emissions while creating clean energy that benefits local communities.
Anaerobic Digestion
Organic materials are converted into biogas that generate renewable electricity while production nutrient-rich digestate for agricultural use.
Fats, Oils and Grease Recovery
Used cooking oils and grease trap materials contain significant energy potential. Walker’s Grease Trap Services team collects and manages these materials before delivering them for anaerobic digestion, where they are converted into renewable electricity.
Alternative Low Carbon Fuels
Recovered wood waste processed into alternative low carbon fuels replace fossil fuels in industrial applications and help produce renewable energy.
Carbon Solutions
The environmental benefits of renewable energy extend beyond energy production. Walker develops and manages environmental attributes associated with our renewable energy projects, including carbon credits and emissions reductions, helping organizations meet compliance requirements and voluntary climate commitments.
Solutions for Landfill Sites Across Canada
We harness landfill gas for use as an energy source in partnership with Comcor Environmental. This partnership offers expertise to develop and implement customized landfill gas collection and utilization solutions for landfill sites across Canada.
