PyroGenesis delivers biomass-to-syngas conversion technology

Technology to debut at Innofibre’s newly launched research & pilot stage facility MONTREAL, June 17, 2026 (GLOBE NEWSWIRE) -- PyroGenesis Inc. (“PyroGenesis” or the “Company”) (TSX: PYR) (OTCQX: PYRGF) (FRA: 8PY1), a leader in ultra-high temperature processes and engineering innovation, and a plasma-based technology provider to heavy industry & defense, announces today a collaborative project to convert contaminated biomass into syngas with its client  Innofibre – Centre d’innovation des produits cellulosiques , a CCTT (“College Centre for the Transfer of Technologies”) at the Cégep de Trois-Rivières. The CCTT is focused on the paper and biorefining industry in Quebec. PyroGenesis’ technology was included during the launch of Innofibre’s new $14 million pilot and pre-commercial facility .

The centre is the only one of its kind in North America equipped to operate under conditions mimicking those of industrial production. The goal of Innofibre’s facility is to accelerate the development and commercialization of innovative solutions related to the forest industry and agricultural biomass (including, but not limited to, bio-based products, biomaterials, biochar, waste valorization and decarbonization, and tailings recovery). The official opening of the facility included speeches by Jean Boulet, Quebec’s Minister of Labour and MNA for Trois-Rivières, representatives from funding partners Canada Economic Development and the Fonds du Grand Mouvement Desjardins, and Jean-Philippe Jacques, General Manager of Innofibre.

Attending for PyroGenesis were Jean-René Gagnon, Director of Engineering, Jenosan Annamalai, Process Engineer, and Yves Bilien, Project Manager for High-Temperature Processes and Thermal Plasma. The system delivered by PyroGenesis will convert contaminated biomass to synthesis gas (syngas). Biomass is organic material from plants and animals, with the plant materials including wood chips, pellets, firewood, and agricultural residues.

Biomass-derived syngas reduces dependence on fossil fuels while supporting decarbonization efforts and the achievement of global climate objectives. The inclusion and successful treatment of contaminated biomass increases the overall amount of biomass feedstock available for syngas production. Contaminated biomass can contain paint, solvents, and a variety of other chemicals and materials such as melamine that can get mixed into biomass in landfills or were added to wood products during manufacturing and prior to being recycled.

PyroGenesis’ high temperature waste-to-energy gasification technology allows for the treatment of contaminants in the produced syngas. The syngas can be used to generate electricity or in the production of a variety of products, including chemicals and fertilizers, methanol, ammonia, synthetic fuels such as renewable diesel and gasoline, and others. “Congratulations to the Innofibre team on the opening of their important new facility,” said Mr. P. Peter Pascali, President and CEO of PyroGenesis. “This centre of excellence is vital to the commercialization of Quebec-based innovations for the bioeconomy, decarbonization, and forestry sectors. We look forward to a continued partnership with Innofibre to help bring new technologies and products to global markets, while also helping to make a greener economy.” Image: PyroGenesis’ engineering team representatives: Yves Bilien, Jenosan Annamalai, and Jean-René Gagnon, stand in front of PyroGenesis’ new technology for converting contaminated biomass into syngas, at the official opening of Innofibre’s new $14 million Cellulosic Products Innovation Centre.
