Mumbai News: BMC Receives Bids For ₹2,368 Crore Biomining Tender To Clear 185 Lakh Tonnes Of Legacy Waste At Deonar Dumping Ground

Mumbai: The BMC has opened bids for the Rs 2,368 crore bioremediation project aimed at treating 185 lakh tonnes of legacy waste at the Deonar landfill. A total of three firms have submitted bids — two infrastructure companies and one firm already involved in BMC's waste-to-energy project. The ambitious three-year cleanup is expected to clear the way for housing tenements under the Dharavi Redevelopment Project.

On May 14, the BMC floated a tender for the bioremediation of legacy waste at the Deonar landfill, with the goal of clearing 2,300 tonnes of waste daily using a fleet of 1,200 vehicles. During a pre-bid meeting held on May 23, around 21 companies raised queries and concerns regarding the project’s scope and execution.

This led the civic body to extend the bid submission deadline three times. The tender process finally closed on July 4, with three bids received. The proposals were opened on Tuesday, with Navayuga Engineering Company Ltd., Re Sustainability Ltd., and H.G. Infra Engineering Ltd. emerged as leading contenders for the project.

While Navayuga Engineering Company Ltd. and H.G. Infra Engineering Ltd. brings extensive experience in infrastructure development, the third bidder, Re Sustainability Ltd., is already involved in waste-to-energy (WTE) operations at the Deonar landfill.

This initiative focuses on converting municipal solid waste into energy and aiming to reduce the landfill burden while generating electricity. The WTE plant is expected to be commissioned by October 2025, with plans to process 600 metric tonnes of waste daily and generate 7 megawatts of electricity.

“The documents submitted by all three companies will now be scrutinised, and the financial bids will be opened on July 11. After that, the technically qualified bidder with the lowest quote will be awarded the contract,” said a senior civic official.

Deonar dumping ground, operational since 1927, is Mumbai’s oldest and largest landfill. Spread across 120 hectares, it is burdened with massive mounds of untreated waste and remains a major environmental concern for the city.

During the pre-bid meeting in May, prospective bidders had raised key concerns, particularly over the availability of additional land parcels for depositing treated waste. Many also questioned the feasibility of clearing nearly two crore metric tonnes of legacy waste within the tight three-year deadline.
