Solid waste management (SWM) is one of the most challenging issues owing to lack of authentic data on different elements of SWM, namely, storage, collection, transportation, separation, processing and disposal. This study presents an assessment of existing status of SWM in conjunction with municipal solid waste (MSW) generation rates, physical and chemical characterization of MSW in high-altitude sub-tropical regions. Weighing of empty and fully loaded trucks per trip revealed total quantity of MSW collected. The average efficiency of MSW collection was 70%. From the baseline data, it is inferred that the population and MSW generation rates are not co-related. The collected MSW included biodegradables (organic wastes), paper, plastic, glass, ceramics, metals, inert materials, ash and debris. The data analysis indicated that the biodegradable components dominate the characterization at 54.83% followed by inert, ash and debris at 21.06%, paper at 8.77%, plastic at 8.18%, glass and ceramics at 4.45% and metals at 2.71%. Statistical measures were also applied and 90% confidence interval (CI) was generated for the characterization data measuring its statistical significance.
由于缺乏关于固体废物管理（SWM）不同环节（即储存、收集、运输、分类、处理和处置）的可靠数据，固体废物管理是最具挑战性的问题之一。本研究结合城市固体废物（MSW）产生率以及高海拔亚热带地区城市固体废物的物理和化学特性，对固体废物管理的现状进行了评估。通过称量每次行程中空车和满载卡车的重量，得出了收集的城市固体废物总量。城市固体废物收集的平均效率为70%。从基线数据推断，人口与城市固体废物产生率并无关联。收集的城市固体废物包括可生物降解物（有机废物）、纸张、塑料、玻璃、陶瓷、金属、惰性材料、灰烬和碎片。数据分析表明，可生物降解成分在特性中占主导地位，为54.83%，其次是惰性材料、灰烬和碎片，占21.06%，纸张占8.77%，塑料占8.18%，玻璃和陶瓷占4.45%，金属占2.71%。还应用了统计方法，并为特性数据生成了90%置信区间（CI）以衡量其统计显著性。
