Pyrolysis (or thermolysis) and gasification are two thermal processes aimed at treating waste containing a combustible fraction. Those processes are characterized by a treatment applied without oxygen (pyrolysis) or with a small quantity of oxygen (gasification). These 2 process families lead to the production of a poor gas, which is most often recycled (burned) on site with low excess air. This is where it is interesting to use the TurboPlasma process, since it enhances syngas quality. Pyrolysis generates a solid by-product (minerals, metals), as well as a carbon-rich combustible fraction. The gasification process generates a solid by-product, which also comprises the incombustible fraction of the treated waste but which only has a very small amount of carbon (unlike the solid pyrolysis residue). After separating the metals, this by-product can be vitrified for recycling using Europlasma technology.
