Here it stands. Can you smell it? Welcome to the Okhla Landfill. This is a place where Delhi’s discards tell a story. It’s a story of waste and, surprisingly, of transformation.
The Okhla Landfill began its journey in 1996. The South Delhi Municipal Corporation needed a place to put the city’s refuse. So this 40-acre site became the designated dumping ground. Imagine 1200 tonnes of waste arriving daily. This continued until 2018.
The landfill grew to a height of 55 meters. That’s almost three times the allowed limit. The site was declared full in 2010. Yet, waste kept coming for eight more years.
But here’s where the story takes a hopeful turn. The SDMC decided to stop dumping waste here in 2018. They envisioned something different for the Okhla Landfill: a green space. The goal was ambitious. The civic agency aimed to remediate the entire landfill in just a year and a half.
Today, the Okhla Landfill is being converted into an eco park. The height has been reduced to 38 meters. About 7000 square meters have been planted with grass. The ultimate goal is to reduce the height to 30 meters. This transformation involves around 58 workers in two shifts.
The grass will be maintained using water from the Okhla wastewater treatment plant. The Sri Ram Institute of Industrial Research analyzed the area. Their study found that the organic waste had decomposed. Only industrial waste remained.
The remediation process involves biomining. This environmentally friendly technique separates different materials. These materials include soil, construction debris, and recyclables. Recyclables are then sorted and sent for reuse or disposal.
Mobile sorting machines are used to process the waste. These machines can handle 7000 tonnes of waste daily. The waste is separated into three fractions based on size. These fractions are then handled differently.
Waste smaller than 30 millimeters goes to the National Highway Authority of India. Larger waste goes through ballistic separation to remove stones. The remaining combustible materials are further processed.
The Delhi government plans to remediate the Okhla Landfill completely. The initial target was to clear it by the end of 2023. The work continues and significant progress has already been made.
However, challenges remain. Fresh waste is still occasionally dumped at the site. Informal waste pickers also operate here. This poses occupational hazards. The quality of the soil-like material is also under scrutiny. There are no national standards to ensure it’s safe for reuse.
The Okhla Landfill is more than just a dumping ground. It represents Delhi’s struggle with waste management. But it also shows the potential for change. It stands as a testament to what can be achieved with vision and effort. The transformation of Okhla Landfill is a continuing story. It’s a story of hope and a greener future for Delhi.
