This R & D project aims at adapting an existing pilot pyrolysis process (250 kg/h) for the decontamination of reconstituted wood wastes (particleboard, plywood, OSB, laminated wood, etc.) and upgrade them, whilst complying with regulatory standards for reducing greenhouse gas emissions and air pollutants. In these wastes, wood generally contains nitrogen-rich thermosetting resins (aminoplast resins) and other various chemical additives. The first phase of this project is to adapt the "CarbonFX" fast pyrolysis technology to optimize the removal of wood waste contaminants. The technological adaptation will mainly focus on the combustion chamber to favour an optimal combustion of the pyrolysis gases and integrate a new aftertreatment device to capture the residual gas pollutants. The second phase of the project is to provide the CarbonFX pilot unit with a novel activation module of biochar. The benefits of this module are twofold: i) it will be a further treatment for full recovery of all types of residual contaminants; and (ii) it will enable the transformation of biochar into activated carbon with high industrial potential. The project will also promote the recycling of carbon dioxide (CO2) from pyrolysis and activation systems and water vapor for use as activators. The energy self-sufficiency of the system and the zero or negative cost of the wood waste will favour both economic viability and environmental performance of the proposed integrated process.
