To identify variation factors of property and quality, solid recovered fuels(SRF) produced from two facilities in Korea were analyzed for moisture, combustibles and ash content, heavy metals concentration, progress comparison. The results show that SRFs quality is suitable for Korean criteria of management, however, production efficiency and quality of variation is so large to compare seasonally. It may be caused by input waste property of regional and progress characteristics. Further research could be verify detailed reasons through mass balance survey and repeated RDF quality analysis comparing with input waste composition.
