Thermal treatment of waste with energy recovery constitutes an excellent option for waste management. TTPL is a founding member of the WTERT in Greece whose purpose is the sustainable management of solid wastes in Greece. It is a member of the worldwide network of WTERT organizations. With respect to mass burn incineration TTPL has experimental facilities for the complete physicochemical characterization of fly ash samples as well as leaching tests. Our research regarding the stabilization of fly ash is carried out using real samples from WtE plants. Furthermore, research is made on the Plasma Gasification process for waste treatment. Plasma arc gasification offers a solution that could effectively and safely dispose municipal as well as hazardous and toxic wastes generated by the residential, commercial, and industrial sectors. Our research in this area focuses on the thermodynamic analysis of plasma gasification technology, which includes prediction of the produced synthesis gas and energy/exergy calculations. To that purpose, an equilibrium plasma gasification simulator, called GasifEq, has been developed.
