Carbonity is the largest biochar plant in North America

This project is the activation of a major partnership between Airex Energy and Suez Group, to produce 350 000 tons of biochar by 2035.

Born from a joint venture between Airex Energy, Suez Group and Groupe Rémabec, Carbonity will produce 30 000 t./year of biochar

Airex Energy has developed a new system leveraging the CarbonFX technology called CarbonFX-HT to produce biochar and biocarbon through carbonization, a higher temperature pyrolysis.

The plant will start producing in Q1 of 2025 using Rémabec's sawdust residues to produce high quality biochar and biocarbon.

Strategic location

The plant is strategically located in Port-Cartier, Québec for the the following reasons:

Close access to biomass residues (located on the sawmill’s lot)
Near a deep-sea port for efficient shipment
Long-term sawmill residues supply

Biochar & Biocarbon

Produced from forestry and agriculture biomass, biochar offers several benefits: carbon sequestration, increased nutrient retention, optimized water availability and soil aeration. It was identified by the Intergovernmental Panel on Climate Change (IPCC) as one of the five most efficient negative-emission solutions. It can sequester CO2 in the soil or in materials for several hundred years. Biochar is one of the five negative emissions technologies identified by the IPCC to curb global warming. As for biocarbon, it is a solution for greener metal production.
