LG Sandhu Conducts On-Site Review of Bhalswa Landfill Bioremediation Efforts
In a significant move to address Delhi's persistent waste crisis, Lieutenant Governor Taranjit Singh Sandhu visited the Municipal Corporation of Delhi's Bhalswa landfill on Monday. The inspection focused on reviewing the ongoing bioremediation work aimed at flattening the massive garbage mountain that has long plagued the city.
Addressing Legacy and Fresh Waste Inflows
During the site visit, Sandhu emphasized the dual challenge of managing not only the accumulated legacy waste but also the continuous daily inflow of fresh garbage. He directed officials to implement robust strategies to tackle both aspects comprehensively, noting that sustainable solutions require addressing the source of waste generation alongside remediation efforts.
Sandhu recalled Prime Minister Narendra Modi's 2021 Swachhata Diwas declaration, where the Bhalswa, Ghazipur, and Okhla landfills were labeled "mountains of shame" and targeted for elimination. While acknowledging progress since then, he stressed that considerable work remains to fully remediate these sites.
Technological Inspection and Waste Conversion Processes
The LG closely examined trommelling machines actively engaged in waste segregation and remediation activities. He witnessed firsthand how municipal solid waste is being transformed into useful byproducts: refuse-derived fuel for waste-to-energy plants, construction and demolition materials for reuse, and inert material primarily used for filling purposes.
Sandhu advised the corporation to explore emerging global technologies in waste management and accelerate outcomes by adopting international benchmarks. He highlighted that leveraging advanced innovations could significantly enhance efficiency and environmental sustainability.
Community Involvement and Segregation Emphasis
A key point of discussion was the critical need for community participation in waste management. Sandhu emphasized involving resident welfare associations and traders' associations in markets to promote segregation of waste at source into dry and wet categories. He noted that proper segregation is fundamental to achieving faster and more effective bioremediation results.
With summer approaching, the LG directed the civic body to urgently implement preventive measures to avoid fire incidents at the city's dump sites, citing seasonal risks that require proactive management.
Quantitative Progress and Remaining Challenges
Officials provided detailed updates on the landfill's status: the Bhalswa site, spread over 70 acres, had received approximately 73 lakh metric tonnes of waste as of November 2022. Of this, 45 lakh metric tonnes were biomined by December 6, 2024. Subsequently, about 39.8 lakh metric tonnes, including fresh waste added at a rate of nearly 4,000 metric tonnes daily, were also processed.
Currently, around 13.5 lakh metric tonnes of legacy waste and 14 lakh metric tonnes of fresh waste accumulating since March 2025 remain to be biomined. To expedite the process, extra trommelling machines are being deployed at the site.
Worker Welfare and Safety Directives
Sandhu also interacted with workers at the landfill to understand their concerns and assess working conditions. He directed authorities to ensure that all necessary health and safety safeguards for workers are strictly maintained by concessionaires, underscoring the importance of protecting those on the frontlines of waste management operations.
This comprehensive review underscores Delhi's ongoing efforts to transform its waste management infrastructure, balancing technological advancement with community engagement and worker welfare to address environmental and urban challenges.
