The gasification and melting system was developed for solution of shortage of dumpyards and curbing dioxins emitted from incinerators. This system is spreading from enact newnormative guidelines for curbing dioxins emitted from incinerators and the wide-area waste disposaland recycling plan. However, the gasification and melting system is influenced by the difference ofwaste composition by socio-economic activity. In this study, we used several Refuse Derived Fuel (RDFs) for the pyrolysis experiments. We measured the mass balance of char, tar, and pyrolysisgases to understand their influence on different pyrolysis conditions and compositions of waste. Thefive following items, 1) lower calorific value of char and pyrolysis gas, 2) generation ratio of char, 3) processing speed of waste, 4) the fuel ratio of char, 5) pyrolysis temperature, were selected todetermine the most suitable pyrolysis condition for gasification melting system. It was found out thata pyrlysis temperature at 500°C was the most suitable condition.
