The refuse-derived fuel (RDF) is manufactured using waste plastics-based materials and its physical and chemical properties are analyzed. The manufacturing process consists of hand picking, primary magnetic separation, crushing, secondary magnetic separation, feeding and extrusion. The RDF products have a high calorific values with over 6,000 kcal/kg and high stability because the waste plastics and paper are mainly used. In the present work, combustion tests with RDF products are conducted and the combustion flue gas is also analyzed to evaluate the air pollution characteristics. The combustion flue gas of RDF products is satisfied with the emission criteria of incinerator. The heavy metal concentration of combustion byproduct from the RDF boiler is also satisfied with the criteria and appears to be lower concentration than that of a common municipal waste incinerator.
