India is witnessing the formation of many densely populated megacities where management of burgeoning wastes, both municipal solid waste (MSW) and industrial hazardous waste (IHW), has become a very critical issue. The city municipalities are showing their inability to manage the waste efficiently. In this paper, the core indicator of environmental pressure, i.e., per capita municipal solid waste (MSW) generation for the top 10 most populous Indian cities and their trend over the years, has been ascertained to understand the severity of the problem. The study finds that the MSW generation per capita is increasing in all the top 10 populated cities of the country. In terms of growth of MSW generation, the city Surat and Delhi grew alarmingly at the rate of 2172% and 1036%, respectively, during the period 1971 to 2015. The level of per capita waste generation of three large Indian cities, i.e.,, Chennai, Kolkata, and Mumbai, was almost at par the level of OECD member countries. All the 10 cities are broadly indicating the existence of "coupling," i.e., the standard of living increments was associated with an increase in MSW generation per capita. The city of Mumbai is also facing the challenge of managing the growing IHW generation as well. However, the city municipalities are helplessly witnessing untreated waste lying for months and years at dumpsites. The reported case of contaminated waste dumping sites raising concern toward imminent health hazards for the city dwellers. To counter the waste-related health hazards, the municipalities the top 10 cities first required to launch "generators as segregators" program for efficient handling of generated waste followed by pay-as-you-throw (PAYT) system to discourage waste generation without any delay.Implications: The burgeoning per capita municipality solid waste (MSW) generation for the top 10 most populated Indian cities and their upward trend through 1971 to 2015 calls for the need for scientific disposal of waste and policies to encourage waste minimization with the adoption of cleaner technologies. A complete mismatch between population increase and waste processing capacity increase, in the case of the top 10 populous cities of India, is raising a concern toward imminent health hazards for the city dwellers. This paper depicted the dismal MSW and IHW management performance in populous Indian cities and proposed a strategy for realistic measurement and management of waste.

快速发展的印度城市的废物产生和管理状况:回顾。

印度目睹了许多人口稠密的特大城市的形成,在这些城市中,城市固体废物(MSW)和工业危险废物(IHW)等新兴废物的管理已成为非常关键的问题。市政当局表明他们无法有效管理废物。在本文中,已经确定了环境压力的核心指标,即印度十大人口最多的城市的人均城市固体废物(MSW)产生及其多年来的趋势,以了解问题的严重性。该研究发现,在该国所有前十大人口稠密的城市中,人均城市生活垃圾产生量正在增加。就城市固体垃圾产生量而言,苏拉特和德里在1971年至2015年期间分别以2172%和1036%的速度惊人地增长。钦奈,加尔各答和孟买这三个印度大城市的人均垃圾产生量几乎与经合组织成员国的水平相当。所有10个城市都大致表明存在“耦合”,即生活水平的提高与人均城市生活垃圾产生量的增加有关。孟买市也面临着管理日益增长的IHW一代的挑战。但是,市政府无奈地目睹了未经处理的废物在垃圾场数月和数年的躺在。报告的废物倾倒场污染案例引起人们对城市居民迫在眉睫的健康危害的关注。为了应对与废物相关的健康危害,前十大城市首先要求启动“发电机作为隔离器” 有效处理产生的废物的计划,然后采用现收现付(PAYT)系统立即阻止废物的产生。含义:人均密度最高的印度十大城市和城市中人均城市固体废物(MSW)的产生迅速增长它们从1971年到2015年的上升趋势要求科学处理废物,并采取政策鼓励采用更清洁的技术来减少废物。在印度人口最多的十个城市中,人口增加与废物处理能力增加之间完全不匹配,这引起了人们对城市居民迫在眉睫的健康危害的担忧。本文描述了印度人口稠密的城市中城市固体废弃物和IHW管理状况不佳的情况,并提出了一种切实可行的废物计量和管理策略。
