Recycling Debris

Circular Economy in India

Introduction

India stands at a critical juncture where rapid urbanization and infrastructure development are generating unprecedented amounts of construction and demolition waste. With the country expected to become the world's third-largest construction market by 2025, generating over 500 million tonnes of construction and demolition (C&D) waste annually, the need for sustainable debris management through circular economy principles has never been more urgent.

The circular economy model offers a transformative approach to India's waste crisis, moving beyond the traditional "take-make-dispose" linear model to embrace "reduce-reuse-recycle" strategies. This paradigm shift not only addresses environmental concerns but also unlocks significant economic opportunities, with experts estimating that India's circular economy could be worth $2 trillion and create 10 million jobs by 2050.

Current State of Construction Waste in India

India generates between 112 and 431 million tonnes of C&D waste annually, depending on various assumptions and calculations. However, official records significantly underestimate this figure, with most waste ending up in landfills or being dumped illegally. Currently, only about 1% of this massive waste stream is recycled through the country's 34 operational C&D recycling plants, most having a capacity of less than 500 tons per day.

The construction industry consumes substantial natural resources, with buildings consuming significant energy and having potential savings of 30-40% through efficient practices. The waste composition includes concrete, bricks, wood, metal, rubble, plaster, stone, and ceramics, all of which have potential for reuse and recycling when properly managed.

Delhi alone produces 6,500 tonnes of debris daily, highlighting the scale of the challenge urban centers face. To address this, the Municipal Corporation of Delhi commissioned India's largest C&D waste recycling plant in 2024, with a capacity to recycle 2,000 tons of waste daily across nearly 7 acres.

Policy Framework and Regulatory Environment

Construction and Demolition Waste Management Rules 2025

The Indian government has taken significant steps to address waste management through comprehensive policy frameworks. The Environment (Construction and Demolition) Waste Management Rules, 2025, which came into effect from April 1, 2026, represent a major advancement in regulatory approach.

Key provisions include:

Extended Producer Responsibility (EPR): Producers of projects with built-up areas of 20,000 square meters or more must prepare waste management plans and ensure recycling. EPR targets require 25% recycling in 2025-26, scaling to 100% by 2028-29.

Mandatory Recycling Targets: Processed C&D waste must be reused in construction activities - 5% in the next two years, increasing to 25% by 2030-31.

Digital Monitoring: A centralized online portal will monitor implementation, with producers required to register and track their waste management activities.

Financial Accountability: Producers can meet targets by purchasing EPR certificates from registered recyclers, ensuring upfront payment for proper disposal.

National Circular Economy Framework

The Confederation of Indian Industry (CII) introduced the National Circular Economy Framework (NCEF) in 2023, expanded in its second edition to cover sixteen materials aligned with NITI Aayog's focus areas. This framework is built on three pillars: Resource Conservation, Waste Reduction, and Climate Resilience.

NITI Aayog has finalized Circular Economy Action Plans for ten waste categories, including construction and demolition waste, with regulatory and implementation frameworks currently being developed across various nodal ministries.
