In this process, anaerobic biomass transforms organics in the raw wastewater (mainly sugars) into methane gas. **Environmental benefits** This biogas fuel is then consumed to dry bleached chemi-thermomechanical pulp (BCTMP) in the final stage of production. The process displaces the light oil previously used, thereby reducing fossil fuel consumption by 87 percent and also reducing greenhouse gas emissions to the environment as well as solid waste to landfill by 24 percent. Biogas fuel currently accounts for 79.5 percent of the Matane Mill’s on-site fuel consumption. **Economic benefits** In addition, installing the anaerobic reactor plant debottlenecked the capacity limitations of the wastewater treatment facility, presenting the opportunity for increased market pulp production.
