WasteManagement – Delhi Faces Major Challenge Clearing Two Landfill Mountains
WasteManagement – Delhi’s ambitious effort to remove two of its massive landfill sites is facing mounting pressure as authorities race against time to process nearly 44 lakh metric tonnes of old waste still lying at the Bhalswa and Okhla dumping grounds. With only a few months left before the targeted deadlines, civic officials continue large-scale biomining operations in an attempt to reduce the towering garbage heaps.
Bhalswa Continues to Carry Heavy Waste Burden
Among the three major landfill locations in the capital, the Bhalswa site remains one of the biggest concerns for authorities. Official figures show that around 26 lakh metric tonnes of legacy waste are still awaiting treatment there, despite ongoing remediation work.
The Municipal Corporation of Delhi (MCD) has already managed to reclaim nearly 35 acres of land through biomining activities. However, the volume of untreated waste continues to remain significantly high. To speed up the process, 24 trommel machines are currently operating at the site to separate reusable materials, soil-like matter, and combustible waste from decades-old garbage deposits.
Delhi Mayor Pravesh Wahi recently stated that the city administration aims to flatten the Bhalswa landfill by the end of 2026 as part of a wider environmental cleanup strategy.
Okhla Site Shows Better Progress but Work Remains Incomplete
Compared to Bhalswa, the Okhla landfill has recorded relatively faster progress in waste processing, although officials acknowledge that the project is still far from completion.
Current records indicate that approximately 18 lakh metric tonnes of waste remain at the site. Biomining operations have already cleared nearly 25 acres of land, while 18 trommel machines are being used to accelerate segregation and processing work.
The original target to flatten the Okhla landfill by July 2026 has now been extended, reflecting the scale of the challenge involved in handling long-accumulated municipal waste. Officials believe continued excavation and processing will be necessary over the coming months to meet revised timelines.
Biomining Remains Central to Delhi’s Cleanup Mission
Delhi’s landfill reduction campaign is heavily dependent on biomining, a waste-processing method designed to recover usable materials from old garbage dumps. During this process, waste layers are excavated and passed through rotating screening equipment that separates recyclable items, soil residue, and refuse-derived fuel.
Authorities consider biomining an important step toward reducing environmental hazards linked to landfill sites, including air pollution, foul odor, and underground contamination.
Despite ongoing efforts, the sheer quantity of waste still remaining at both Bhalswa and Okhla has raised concerns about whether the deadlines can realistically be achieved without increasing processing capacity.
Ghazipur Continues to Be the Largest Waste Challenge
While immediate attention remains focused on Bhalswa and Okhla, the Ghazipur landfill continues to represent Delhi’s largest unfinished remediation project. Official data shows that nearly 67 lakh metric tonnes of legacy waste are still present at the site.
The Ghazipur landfill has been given a longer remediation deadline extending to December 2027. Civic authorities say work is progressing continuously there as well, although the scale of accumulated waste remains extremely high.
Commissioner Reviews Operations at Okhla Landfill
Amid concerns regarding project timelines, MCD Commissioner Sanjeev Khirwar visited the Okhla landfill site on Tuesday to inspect ongoing biomining and waste-management operations.
During the inspection, officials reviewed the functioning of trommel machines and discussed measures to accelerate the clearance of old garbage. The commissioner also examined operations at the construction and demolition waste facility, the engineered sanitary landfill zone, and the Okhla Compost Plant.
Delhi’s landfill cleanup programme remains one of the capital’s most closely watched urban infrastructure projects, with environmental experts and residents alike monitoring whether the city can successfully reduce its long-standing garbage crisis within the promised timelines.
