Abstract
The present invention relates to a process and system for thermal waste treatment. The method according to the invention comprises subjecting the waste to thermolysis in a furnace to produce from the waste thermolysis gases and carbon containing solids; purifying the carbon containing solids into purified carbon containing solids which contain pollutants; using part of the thermolysis gases as fuel which is burned to heat the waste in the furnace; burning in a cyclone furnace at least part of the purified carbon containing solids containing pollutants to produce hot gases and to immobilize the pollutants present in the purified carbon containing solids into solids containing the pollutants; and providing the hot gases to an energy recovery device and using the energy recovery device to recover energy from the hot gases.
