The Brihanmumbai Municipal Corporation (BMC) has awarded a Rs 25.4 billion contract to Hyderabad-based Navayuga Engineering Company (NEC) to bioremediate 18.5 million tonne of legacy waste at Mumbai’s Deonar dumping ground, one of Asia’s largest and oldest landfills.

The project aims to reclaim approx. 110 hectares of land, which will later be allocated for residential construction under the Dharavi Redevelopment Project—a collaboration between the Adani Group and the Maharashtra government’s Slum Rehabilitation Authority (SRA). BMC had floated a Rs 23.68 billion tender in May for the bioremediation work.

NEC emerged as the lowest bidder at Rs 1,373.35 per tonne. NEC’s work involves excavation, segregation, and treatment of waste, transforming the site into usable land over a three-year period, including time for mobilisation and monsoon delays. 

NEC, established in 1986, has prior experience with large-scale infrastructure projects and has previously partnered with the Adani Group.
