The Brihanmumbai Municipal Corporation (BMC) is set to finalise one of its largest-ever waste clearance contracts to clear Mumbai's Deonar dumpyard within three years. The INR 2,368 crore project aims to remediate nearly 185 lakh tonnes of legacy waste using sustainable bioremediation techniques. Once completed, the reclaimed 311-acre land can be reused, including for the Dharavi Redevelopment Project. With tenders closing in May 2025, the selected contractor will be responsible for safely disposing of waste and converting it into usable materials like inert matter, recyclables, and soil fillers. The project is part of a broader push for cleaner, safer urban environments.
Mumbai's Deonar dumpyard, one of the oldest and largest landfills in India, is now at the centre of a INR 2,368 crore legacy waste remediation project. The Brihanmumbai Municipal Corporation (BMC) has floated tenders for the project, and the final contractor is expected to be announced by May 2025. The goal is to complete waste clearance in three years using eco-friendly bioremediation techniques. Advertisement
The Deonar site has accumulated nearly 185 lakh tonnes of waste over decades. The mountain of garbage, in some parts rising up to 40 meters, has been a long-standing source of pollution, health hazards, and fires, often affecting nearby areas like Govandi and Chembur.
Under the proposed plan, the selected contractor will use sustainable methods such as bio-inoculation and waste sorting to convert legacy waste into usable outputs. These include inert materials like stones and bricks, recyclable metals and glass, combustible items for waste-to-energy projects, and soil-like material to be used as filler for low-lying areas.
The project covers a total area of 311 acres at Deonar, of which 124 acres are planned to be reclaimed. Of the remaining, 136 acres are already in use and 51 acres lie on an unusable marshland. The final outcome will be the creation of usable, reclaimed land, which is expected to support upcoming urban projects, including the much-delayed Dharavi Redevelopment.
State government officials have asked the BMC to speed up the clearance of Deonar waste to make way for related infrastructure in the Dharavi region. However, the move has sparked political criticism. Shiv Sena leaders have raised concerns about the state transferring land from Mumbai to the Adani Group for processing solid waste from Dharavi. They argue this shifts the financial burden to Mumbai taxpayers.
Local residents and civic activists have long demanded action to address the air and water pollution caused by the dump. With daily waste intake at Deonar averaging over 23,000 tonnes and 1,200 vehicle trips, the site remains heavily overburdened. Environmental approvals and regulatory compliance will be key to keeping the project on track.
If completed successfully, this project could mark a major milestone in Mumbai's solid waste management policy, transforming one of its most toxic sites into a model for urban land reclamation.
