Refused-derived fuel (RDF) is a renewable energy source to produce energy as a replacement of fossil fuels, and analyzing the characteristics of municipal solid waste (MSW) is a critical issue to investigate possible energy sources. This study aimed at conducting laboratory analysis of solid wastes existing in the study area and investigating their characteristics. Moisture content, ash content, calorific value, total chlorine content, inorganic chlorine content, and heavy metal content were selected as objects of the analysis and the results were compared with measurements of previous studies. Gross calorific values (GCVs) vary between 14.6 and 40.2KJ/g. Especially, plastic is significantly high in calorific values, presenting 33.6 ± 0.5, 40.2 ± 1.0, and 28.6 ± 0.4 for non-packaging hard plastics, packaging foils, and packaging polyethylene terephthalate (PET), respectively. Total chlorine contents are less than 4 mg/g, except for non-packaging hard plastics. Cadmium contents of organic kitchen waste (KW) and non-packaging hard plastics (HP) respectively are below the detection limit and the lead content of KW is also below it. As the analysis result shows, the investigated samples could be used as RDF and can produce energy by several energy conversion methods.
