Material resource recovery from municipal solid waste in India: Policy evolution,implementation challenges,and the path forward

Abstract

India’s rapidly urbanizing cities face severe challenges in municipal solid waste management as waste generation surges, creating tensions between development and environmental sustainability. Despite comprehensive policy frameworks that emphasize circular economy principles, significant gaps persist between policy intentions and on-the-ground implementation, particularly regarding material resource recovery systems. This research delivers the first comprehensive mixed-methods examination of India’s waste management policy evolution, uniquely integrating formal policy evaluation with informal sector dynamics across varied urban settings. Unlike previous studies focusing on isolated aspects, this work provides an integrated analysis spanning governance, economics, technology and social dimensions while examining the critical intersection between formal regulatory frameworks and extensive informal recycling networks characterizing India’s waste management landscape. The study employs a triangulated research design combining systematic literature review (89 peer-reviewed documents), comparative case study analysis of 10 urban local bodies representing diverse geographic regions and governance structures, and extensive field observations with semi-structured stakeholder interviews (n = 45) from January 2023 through March 2024. India generates over 58 million tonnes of waste annually with 90% collection but only 48–50% treatment, representing critical implementation gaps. Analysis reveals 60–65% comprises organic matter while 30–35% consists of recyclables worth US$4 billion annually, largely unrecovered. Cities with integrated governance frameworks achieve 35–40% higher material recovery rates (p < 0.01). Major barriers include inadequate infrastructure, fragmented governance, economic disincentives and unstable recycling markets. The persistent collection–treatment gap requires synchronized interventions across governance, infrastructure, economic incentives and stakeholder engagement.
