초록

This study was to select five places among apartment houses (apartment), detached houses (including houses, villas), downtown area (markets, shops, restaurants) being operated in Korea and use the analysis of physical and chemical characteristics for treatment residues of weight reduction equipment as basic data. Also, we were to evaluate the recyclability by determining whether discharged treatment residues are available in the thermochemical process such as cement sintering facilities and power plants in which energy can be recovered based on the quality standards of Bio- SRF and SRF. Three components for food waste were analyzed and as a result, moisture average, combustibles average and ash average were found to be 11.9% (2.0 ~ 24.8%), 78.9% (63.3 ~ 93.0%) and 9.2% (5.0 ~ 11.9%) respectively and all of them were found to satisfy less than 25%, the moisture content standard of Solid Refuse Fuel (SRF) products. The results of the elemental analysis were analyzed to be carbon average 49.71% (48.41 ~ 52.14%), hydrogen average 6.62% (31.32 ~ 40.63%), oxygen average 37.92% (31.32 ~ 40.63%), nitrogen average 3.82% (2.79 ~ 5.81%), sulfur average 0.26% (0.19 ~ 0.46%), chlorine average 1.67% (1.10 ~ 3.16%). In addition, the low-heating value measurement result is average 4,016.6 kcal/kg (3,255.9 ~ 4,657.9 kcal/kg) and turned out to satisfy most general Solid Refuse Fuel (SRF) product standards but that of Facility E is 3,255.9 kcal/kg and was analyzed not to meet the quality standard 3,500 kcal/kg.
However, if maintaining the moisture content of treatment residues to 20% or less, it is determined to satisfy the caloric value standards of general Solid Refuse Fuel products.
