Our country is not established MSW analysis and method of basic experimentation for MBT SYSTEM which decide to size of each process. In order to get the fundamental data which is necessary to plan of MBT SYSTEM, this study has improved existing MSW analysis for incinerator and phrolysis melting system into new MSW analysis for MBT SYSTEM. The result of study is able to decide to Classification-Efficiency and size of each process to MBT SYSTEM. This is able to expect characteristic of RDF which is a final product of MBT SYSTEM.
