Waste material is incinerated by a partial combustion in a furnace on step grates and the heated combusted product is supplied in a rotary kiln in which the waste is liquified. Solid waste material passing through the grate is collected with ash products, separated from flue gases, including boiler ash, fly ash and residue from flue gas cleaning. The collected products are returned to the inlet of the rotary kiln where these products are introduced along with he combusted waste. In this manner, the slag, boiler ash, flue ash and other harmful residual products from the combustion process are fused into the liquified waste to form a glass-like mass from which salts and heavy metal cannot be leached out.
