FIELD: manufacture of building materials. SUBSTANCE: fuel-containing waste is crushed and supplemented with additives converting it into a blend suitable to produce desirable building material. Blend is melted in a cyclone melting unit wherein temperature is controlled with additionally installed fuel burners. Melting unit is installed as burner means in baking furnace wherein off-gas heat is utilized to dry and bake additional amount of raw material. Air introduced into melting unit is preheated with baking furnace off-gases in a heat exchanger installed after baking furnace. EFFECT: completely utilized heat value of waste and achieved stable operating condition. 10 cl, 1 dwg
