Main part of the contribution is devoted to analysis of the process of thermal plasma waste treatment, gasification and pyrolysis. In the recent experiments we performed gasification of lignite, steam and dry reforming of methane, methanol and ethanol, pyrolysis of methane and decomposition of perfluorinated compounds. Each of these experiments has its specific features. In case of lignite, we have shown that thermal plasma can effectively use the bound water molecules and form hydrogen-rich syngas. Simple methane molecule serves as an example of possibility to form syngas or hydrogen together with high quality carbon particles. For decomposition of perfluorinated compounds the plasma torch with water stabilization is good choice, since presence of water enhances desired reactions. Application of this plasma torch for waste treatment brings the advantage of high energy content in small plasma volume and moreover, minimal dilution of the product by the plasma gas takes place.
