Cooking with gas: circularity in action

Cooking with gas: circularity in action in Quebec

Matane Mill in Quebec produces its own biogas from raw process wastewater using anaerobic reactor technology.

In this process, anaerobic biomass transforms organics in the raw wastewater (mainly sugars) into methane gas. This biogas fuel is then consumed to dry bleached chemi-thermomechanical (BCTMP) pulp in the final step of production.

The process displaces the light oil previously used, thereby reducing fossil fuel consumption by 87% and also reducing greenhouse gas emissions to the environment as well as solid waste to landfill by 24%. Biogas fuel currently accounts for 79.5% of Matane Mill’s on-site fuel consumption. What’s more, installing the anaerobic reactor plant debottlenecked the capacity limitations of the wastewater treatment facility, presenting the opportunity for increased market pulp production.
