The debris solution: How can recycling Delhi’s construction waste clean the air?

Construction waste dust is a major Delhi polluter. Watch this video to know how a civic project is collecting and recycling this debris to help the city breathe.

With air pollution levels hovering between the ‘poor’ and ‘severe’ categories, Delhi has been gasping for breath. The air quality has continued to deteriorate, with the capital recording an AQI of 372 on December 2nd, according to the Central Pollution Control Board.

So, is the winter mist coupled with the vehicular pollution only to blame? The reality is more complex than that. Dust from construction activity and malba or construction and demolition (C&D) waste contribute significantly to air pollution in Delhi.

Moreover, managing this waste is a huge challenge for the city’s civic administration, and the majority of C&D waste ends up in the landfill. India generates around 150 million tonnes of C&D waste annually, accounting for 35% to 40% of total waste generated. And only 1% of this is managed and recycled, says a 2020 study by the Centre for Science and Environment.

Eliminating construction waste

But a civic initiative in Delhi and four other States is quietly working to change the narrative. The Air Pollution Action Group (A-PAG) is collaborating with the government to tackle construction debris and improve air quality. Founded in 2019, A-PAG is a non-profit foundation working with the vision of improving air quality to meet basic sustenance levels in India. Their focus is on the indo-gangetic plains as the impact of deteriorating air quality is acute there.

By establishing malba collection points, awareness building and monitoring, the A-PAG team has managed to divert C&D waste from landfills to processing units.

“Strengthening C&D recycling helps cities shift away from mining-intensive construction toward circular urban development,” says Kritika Choudhary. “When RWAs, homeowners and contractors know where to dispose of malba, they become partners in keeping streets clean.”

Kritika Choudhary is the Associate Director and Head – Strategy Planning and Policy at A-PAG. In a video interview with Citizen Matters, Kritika says the team has collected 3.5 lakh metric tonnes of C&D waste over the past two years and has operationalised 67 secondary collection points.

“Scaling secondary collection points, digital tracking, and driving demand for recycled products are the big opportunities for Indian cities,” Kritika said. Citizen Matters discussed with her about the challenges and opportunities that our urban local bodies have in managing the waste. Watch the full interview below.

Beyond the bin: How a Mumbai neighbourhood inspired a community waste recycling movement

From plastic and paper to books, clothes and e-waste, a Shivaji Park initiative has expanded steadily since its first collection drive in 2020.

On the last Sunday of every month, a lane in Mumbai's Shivaji Park becomes a collection point for dry waste.

How one Chennai community is turning household waste into a valuable resource

The KAATRU initiative by SSM Nagar residents has helped divert tonnes of waste from landfills through volunteer action and recycling partners.

The consequences of poor waste management are visible across communities near our own in Chennai. In Tiruvanchery, waste dumped and burnt close to residential areas has caused breathing difficulties, mosquito nuisance, and raised concerns about groundwater contamination. Such conditions don’t begin at dumping grounds alone; they start at home, when recyclable, biodegradable, and non-recyclable materials are discarded together.   For many years, the approach has been standard: collect mixed household waste and transport it to dumping yards. While this may appear convenient, it is neither sustainable nor environmentally responsible. In our own community of SSM Nagar, Perungaluthur, only about 50% of…
