Thermal treatment of waste - Thermochemical processes

Thermal treatment of industrial wastes and effluents is based on various thermochemical transformation processes of matter and energy. These processes involve mass and heat transfer, combined with the reactivity of the material to be treated in the various reaction environments created either for the oxidation, pyrolysis or gasification of their organic fraction, or for the melting of the mineral residues formed. They give rise to various transformation products, which need to be treated before being released into the atmosphere.

These thermochemical processes are used in processes and equipment designed for the elimination and/or material/energy recovery of waste; these will be described in article $\text{Procédés}$ .
