Mumbai’s Deonar Dumping Ground Set for Transformation as BMC Launches Massive Bioremediation Drive

In a major step towards urban renewal and sustainable waste management, the Brihanmumbai Municipal Corporation (BMC) has initiated a ₹2,368 crore project to clear out nearly 185 lakh tonnes of legacy waste from the Deonar dumping ground. This ambitious bioremediation effort is expected to unlock around 110 hectares of prime land over a span of three years, with strong links to the Dharavi Redevelopment Project (DRP).

From Dumping Ground to Redevelopment Zone

The Deonar landfill, which has been operational since 1927, covers approximately 311 acres and has long posed challenges for Mumbai's civic and environmental planning. The new project proposes bioremediation—an eco-sensitive method that uses biological processes to detoxify and manage pollutants. The cleared land is intended to support resettlement plans for thousands of Dharavi residents who are not eligible for in-situ rehabilitation under the DRP framework.

Project Timelines and Logistics

The BMC has designed the initiative to be completed within 36 months, factoring in preparation time and seasonal delays due to the monsoon. Daily removal of 23,000 metric tonnes of waste has been planned, using a fleet of nearly 1,200 vehicles. Environmental safety remains a critical aspect of the plan, particularly due to the site's proximity to the Vashi Creek. Accordingly, the BMC intends to secure clearances from the Coastal Regulation Zone (CRZ) and forest authorities before beginning full-scale operations.

Linking with Dharavi Redevelopment

Back in October 2024, the Maharashtra cabinet had approved the allocation of 124 acres from the Deonar landfill towards the Dharavi Redevelopment Project—a joint venture between the state government and the Adani Group. This reclaimed land is earmarked for constructing rental housing for approximately 50,000 Dharavi residents who fall outside the eligibility bracket for free housing. While the move supports the DRP's scale, it has sparked debate regarding public fund allocation and the suitability of developing housing on a former landfill.

Concerns Over Environmental and Health Risks

Activists and health experts have voiced apprehensions about the potential consequences of building residential complexes on what was once a heavily polluted landfill. With a known history of methane emissions and frequent landfill fires, Deonar has long posed serious health concerns for surrounding areas. Critics believe that the current proposal may fall short on addressing long-term environmental and health impacts unless backed by thorough environmental assessments and continued monitoring.

Looking Ahead: Energy from Waste

Beyond land reclamation and housing, BMC also plans to establish a compressed biogas (CBG) plant on the site in collaboration with Mahanagar Gas Limited (MGL). The proposed facility is expected to process up to 1,000 tonnes of wet waste daily, adding a renewable energy component to Mumbai’s waste management roadmap.
