This paper analyzes the amount and characteristics of municipal solid waste (MSW) according to the inhabitant density of population and the business concentration in 25 districts in Seoul. Further, the heat energy recovery and avoided CO(2) emissions of four incineration plants located in residential and commercial areas in Seoul are examined. The amount of residential waste per capita tended to increase as the density of inhabitants decreased. The amount of commercial waste per capita tended to increase as the business concentration increased. The examination of the heat energy recovery characteristics indicated that the four incineration plants produced heat energy that depended on residential or commercial areas based on population and business. The most important result regarding avoided CO(2) emissions was that commercial areas with many office-type businesses had the most effective CO(2) emission savings by combusting 1 kg of waste. Assuming the full-scale operation of the four incineration plants, the amount of saved CO(2) emissions per year was 444 Gg CO(2) and 57,006 households in Seoul can be provided with heat energy equivalent to 542,711 Nm(3) of LNG.
本文根据人口密度和 25 个首尔地区的商业集中程度,分析了城市固体废物(MSW)的数量和特性。此外,还对位于首尔居民区和商业区的四个焚烧厂的热能回收和避免的 CO2 排放量进行了研究。人均生活垃圾量随着居民密度的降低而增加。人均商业垃圾量随着商业集中程度的增加而增加。热能回收特性的研究表明,这四个焚烧厂产生的热能取决于人口和商业的居民区或商业区。关于避免 CO2 排放最重要的结果是,燃烧 1 公斤废物时,拥有许多办公型企业的商业区可以实现最有效的 CO2 减排。假设四个焚烧厂全面运营,每年可节省 444 万吨 CO2 排放量,首尔市 57006 户家庭可获得相当于 542711 立方米 LNG 的热能。
