THERMAL PROCESSING OF WASTE PLASTICS RAW MATERIAL PROCESS PRODUCT Product is a full value solid fuel. THERMOLYSIS Karboterm Two stage process WP/bitum ratio : 4 / 1 Temp. : 350oC Time: 60 min Ash : 10 % Heating value : 30000 kJ/kg Sulfur : < 0,8 % Chlorine : < 0,2 % 100.000 Mg of wasteplastics per year in Poland Composition Description: Prepared waste plastics are thermally processed with an addition of carbo- or petrochemical bitumens. The reduction of volatile hydrocarbons and elimination of chlorine from polymer decay are characteristic for the process. Hot liquid semi-product is cooled by mixing with a grained hard coal. Product application: Karboterm is a full value component for a coal blend in coking plants or a fuel in power plants with a grained hard coal.
