Due to the problems on BW (Bulky Waste) from SRF (Solid Refused Fuel) facilities in terms of operation andmaintenance, we investigated the characteristics of bulky waste about physical composition ratio, discharge type and ratio,etc. BW are 5.83% in MSW (Municipal Solid Waste) and composition ratio is as below; fiber (28.22%), plastic (19.18%),paper (17.95%), wood (17.02%), metal (11.49%), vinyl (3.3%), styrofoam (2.84%). Paper was mostly packing box, wood;chipboard, pieces of wood, branch, vinyl; big vinyl bag, plastic; home appliance, toy, big piece of plastic, fiber; clothing,mattress, sponge, styrofoam; pieces of styrofoam box, metal; broken metal stuff. BW has characteristics that is bulky andmainly consist of recycle waste compared with general MSW. We compare the composition ratios of only BW, MSWincluding BW and not including BW in order to extend to which variation in BW affects on physical composition ratioof general MSW. As a result of these researches, physical composition ratio between MSW not including BW and BWhas some difference but correspond closely with MSW including BW. This is because BW component ratio is so smallthat have little effect on composition ratio of total waste. Conclusively BW component and physical composition ratio,discharging type should be investigated for characterizing BW. But BW composition ratio needs not to be included onlyfor analyzing physical composition ratio of waste.
