Delhi's Construction Waste Recycling Efforts Fall Short of Targets
New Delhi faces a significant challenge with construction and demolition (C&D) waste, generating more than 6,000 metric tonnes daily. While dedicated recycling plants process much of this debris into reusable materials like paver blocks and tiles, government agencies are struggling to meet consumption targets, raising concerns about urban sustainability.
Low Uptake Despite Revised Goals
According to a recent report submitted by the Municipal Corporation of Delhi (MCD) to the Delhi government, against an annual target to utilise 9.9 lakh metric tonnes of recycled C&D products in 2025-26, government agencies have used only about 1.3 lakh metric tonnes between April 1, 2025, and February 28, 2026. This represents a mere 13% of the target, even after the Ministry of Housing and Urban Affairs (MoHUA) reduced consumption goals this year, terming the revised figures as more "realistic."
Last year, government agencies managed to utilise only 14% of a total target of 16 lakh metric tonnes, highlighting a persistent shortfall in adopting recycled materials for construction projects.
Performance of Key Agencies
The report details the performance of 20 government and public sector undertakings in Delhi:
- MCD was given an annual offtake target of 2 lakh metric tonnes but utilised only 53,479 metric tonnes, achieving 26.7%.
- Delhi Development Authority (DDA) assigned a target of 50,000 metric tonnes, utilised 16,520 metric tonnes, reaching 32.5%.
- Northern Railway did not utilise any part of its 10,000 metric tonne target.
- Public Works Department (PWD), handling a large share of infrastructure projects, used only 2,122 metric tonnes against a target of 1 lakh metric tonnes, a mere 2.2%.
- Delhi Tourism and Transportation Development Corporation consumed only 56 metric tonnes, about 1% of its 5,250 metric tonne target.
Reasons for Low Consumption
Sources cite several factors contributing to the low uptake of recycled C&D products. Concerns over quality have been raised in meetings, with contractors noting that public objections sometimes arise regarding materials used in road works. Additionally, the limited range of available materials poses a challenge.
"Not all products required in construction are available at these plants. C&D waste can produce items like paving tiles, kerbstones, and filling material, which cannot meet the entire requirement," explained sources. This mismatch between supply and demand hinders broader adoption in large-scale projects.
Waste Generation and Processing Infrastructure
Delhi generates approximately 5,500 to 6,000 metric tonnes of C&D waste daily from activities by agencies such as MCD, PWD, CPWD, I&FCD, DJB, and the Delhi Cantonment Board. Around 5,000 metric tonnes is transported to four processing plants:
- Bakkarwala: 1,000 metric tonnes capacity
- Burari: 2,000 metric tonnes capacity
- Ranikhera: 1,000 metric tonnes capacity
- Shastri Park: 1,000 metric tonnes capacity
A fifth plant with a capacity of 1,000 metric tonnes is being established at Tehkhand, aiming to enhance processing capabilities.
Policy and Monitoring Efforts
Under current policy, all civic agencies are required to prioritise the use of recycled C&D materials in construction and road projects. The system has shifted from minimum usage thresholds to annual volume-based targets, with compliance reviewed quarterly. Failure to meet targets may impact contractor payments, according to sources.
Recently, the Prime Minister's Office and MoHUA began monitoring C&D waste collection, setting an initial target to clear 1 lakh metric tonnes within 15 days from March 6 to 21. However, experts warn that if collected waste is not processed or utilised and instead stockpiled, the exercise loses its purpose.
Future Outlook and Challenges
Officials indicate that consumption of recycled materials may not increase significantly unless large-scale infrastructure projects accelerate. "In the case of MCD, budget is allocated to maintenance wards for procuring by-products made from C&D waste every year, but unless major projects are taken up, consumption cannot rise substantially," an official stated.
This situation underscores the need for improved quality assurance, expanded product ranges, and stronger enforcement of recycling mandates to address Delhi's growing C&D waste problem effectively.
