On May 22, 2025, Carbonity, Canada’s first industrial-scale biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More facility, was officially inaugurated in Port-Cartier, Quebec. A joint venture by Airex Energy, Groupe Rémabec, and SUEZ, the plant represents a major step in leveraging forestry by-products for sustainable development and carbon sequestration.

Initially designed to produce 10,000 tonnes of biochar annually, Carbonity is expected to triple its output by 2026, making it one of the largest facilities of its kind in North America. Biochar is created through high-temperature pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More of biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More and is recognized by the IPCC for its long-term carbon storage potential. It also offers practical benefits across multiple sectors: enhancing soil health in agriculture, improving construction material performance, and contributing to energy recovery.

Carbonity utilizes Airex Energy’s proprietary CarbonFX and DryFX technologies, while drawing on SUEZ’s expertise in organic waste recovery and soil improvement. The facility will process 58,000 tonnes of forest residues annually from Groupe Rémabec and is set to create 75 regional jobs.

The plant will sequester an estimated 75,000 tonnes of CO₂ equivalent per year and has already secured a carbon credit purchase agreement with Microsoft for 36,000 credits. With backing from the federal and provincial governments, including over $16 million in support, Carbonity is positioned as a key part of Canada’s decarbonization strategy.

This project marks the beginning of a larger vision: producing 350,000 tonnes of biochar annually by 2035 to accelerate the transition to low-carbon industrial practices .
