The main objective of this work is to use pyrolysis for the production of biochar from the residues of well-established biochemical processes. The residues that were selected come from two major conversion processes: biogas digesters, and wastewater treatment facilities. These processes produce unconverted lignin-rich residues, made of biomass components that are refractory to biochemical conversion. Pyrolysis is an aggressive thermochemical conversion process that is ideally suited to such residues. The desired biochar characteristics were determined by the specific needs of each industrial partner. The desired traits for the biochar obtained from sewage sludge were the capture, and stabilization of heavy metals contained in the sludge, to reduce the release of heavy metals into the environment.
