摘要： 城市生活垃圾管理是全球发展中国家最具难度的挑战。特别是气候、地形和地理条件复杂的山区城市的生活垃圾管理，目前对其的研究很少，数据有限。本文选取喜马拉雅山脉西部克什米尔地区的三个城市（巴拉穆拉、库普瓦拉和班迪波拉）进行研究。目前，该地区城市生活垃圾管理落后，垃圾往往以不科学的方式公然倾倒在附近的河流和湖泊，增加了对地下水和地表水污染的威胁。本研究旨在分析城市固体废物管理系统的现况和垃圾产生速率。采用锥体四分法对城市生活垃圾进行了理化表征，分别采用马弗炉和弹式量热仪对样品进行了工业分析。结果表明，克什米尔城市地区的生活垃圾产量约为181.43公吨/天（巴拉穆拉93.73公吨/天，库普瓦拉57.46公吨/天，班迪波拉30.27公吨/天）。城市生活垃圾的有机废物含量较高（10.3%-68.5%），其次是可回收废物（12.3%-15.30%）和惰性废物（8.27%-9.10%）。此外，化学表征结果表明，上述区域垃圾的平均含水量在47.6%-52.40%之间，并且热值较低（1017-1175.6kcal/kg）。最后，本文还提出了垃圾合成，建造生物甲烷厂，安装回收装置，以及将现有倾倒区升级为卫生填埋场等处置方法。

Abstract: Municipal solid waste (MSW) management is the most challenging environmental issue in developing countries around global municipalities. In mountainous regions, very few studies can be found and the availability of limited data, because waste management poses different challenges due to different climate, topography, and geographical conditions. This study has been conducted in three urban areas of the Kashmir region (i.e., Baramulla, Kupwara, and Bandipora) in the western Himalayas. Presently, waste management is underdeveloped and openly dumped in an unscientific manner near to the rivers, streams, and lakes, which increases the threat of contamination to ground and surface water, respectively. The present study aimed to analyze the current scenario of the MSW management system and its waste generation rates. The Physio-chemical characterization of municipal solid waste was carried out by using a quarter and cone method. Proximate analysis of samples was performed by using muffle furnace and bomb calorimeter for chemical analysis, respectively. The findings of the MSW generation of urban areas of Kashmir were approximately 181.43 Mt/day (93.73 Mt/day in Baramulla, 57.46 Mt/day in Kupwara, and 30.27 Mt/day in Bandipora), respectively. Further, the findings of MSW showed high organic waste between (10.3%–68.5%), followed by recyclable waste (12.3%–15.30%), and inert waste (8.27%—9.10%), respectively. Also, the chemical characterization results showed average moisture content varying between (47.6%–52.40%) with the lower calorific values of (1017–1175.6 kcal/kg) in the areas mentioned earlier. In conclusion, alternative treatment methods were proposed, for instance, compositing, biomethane plants, the installation of recycling plants, and upgrading the existing dumping sites to sanitary-engineered landfills.
