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

Area of Science:

• Environmental Science
• Urban Planning
• Circular Economy

Background:

• Rapid urbanization in India escalates municipal solid waste management challenges.
• Existing policies promote circular economy principles but face implementation gaps.
• Informal sector dynamics are crucial yet underexplored in India's waste management.

Purpose of the Study:

• To conduct a comprehensive mixed-methods examination of India's waste management policy evolution.
• To integrate formal policy evaluation with informal sector dynamics across diverse urban settings.
• To analyze governance, economics, technology, and social dimensions at the intersection of formal and informal waste management.

Main Methods:

• Systematic literature review of 89 peer-reviewed documents.
• Comparative case study analysis of 10 urban local bodies.
• Field observations and semi-structured interviews with 45 stakeholders (Jan 2023-Mar 2024).

Main Results:

• India generates over 58 million tonnes of waste annually, with a significant collection-treatment gap (90% collection, 48-50% treatment).
• Recyclables constitute 30-35% of waste, valued at US$4 billion annually, yet are largely unrecovered.
• Integrated governance frameworks correlate with 35-40% higher material recovery rates (p < 0.01).

Conclusions:

• Key barriers include inadequate infrastructure, fragmented governance, economic disincentives, and unstable recycling markets.
• Addressing the collection-treatment gap necessitates synchronized interventions in governance, infrastructure, economic incentives, and stakeholder engagement.
• Policy implementation requires bridging formal regulatory frameworks with informal recycling networks for effective resource recovery.
