Abstract

Results for application of RDF(Refuse Derived Fuel) to selected wastes in metropolitan and small
and medium cities are as follows. The physical characteristics of waste are paper, plastic, food waste,
and so on. The proximate analysis in P city showed 20.2% of moisture, 71% of combustible material,
and 8.8% of ash on annual average. That in G city showed 31.6% of moisture, 59.5% of combustible
material, and 8.9% of ash. Ultimate analysis in P city showed 52.04% of carbon, 7.02% of hydrogen,
28.80% of oxygen, 0.66% of nitrogen, and 0.09% of sulfur. Heating value was 3,363 kcal/kg. Ultimate
analysis in G city showed 50.85% of carbon, 6.56% of hydrogen, 29.86% of oxygen, 0.79% of nitrogen,
and 0.12% of sulfur. Heating value in the G city was somewhat lower than that in the P city with
2,632 kcal/kg. Thus, application of RDF in metropolitan city was more effective than that in small and
medium cities. Heating value in mixture for the P city was lower than that in waste of the volume
rate waste charge system alone by 143 kcal/kg. In proximate analysis, moisture, and combustible material
were likely to be more adequate to RDF.
