Before the pyrolysis process takes place at our production site, the carbon cycle begins in the forests. Unlike fossil fuels, biomass does not take centuries to form. Every year, trees absorb significant CO2 amounts from the atmosphere, thus working towards mitigating climate change. Nurturing this cycle through sustainable forest management is at the core of our company’s activity.
Once the collected wood residues have arrived at our site, we begin to prepare them for the pyrolysis process by chopping and drying them. The energy needed for this phase is entirely provided by the heat production that takes place within the facility.
The following stage consists in heating the biomass residues to high temperatures in the absence of oxygen. This phase is carried out in several pyrolysis reactors* which have been designed to operate in cycles, thereby ensuring the continuous operation of the entire plant.
The reactors are interconnected so as to collect the produced pyrolysis syngas, an excellent energy carrier. The pyrolysis gas is then converted into syngas, which can be used, for example, in the cogeneration unit, which converts its thermal energy into heat used for drying the wood, and electricity made available to local communities.
After being cooled down, the solid biocarbon produced during the pyrolysis process – and which was originally stored in the wood as organic carbon – continues its journey to the industrial customers to help them offset their carbon emissions and create carbon sinks. This way, the Carbonex technology builds a bridge between sustainable forests and a carbon neutral economy.
