Dhapa Waste Mining Stalls, Delays Landfill and Poses Risks
Imagine a giant trash pile in Kolkata called Dhapa.
For years, trash has been building up.
The city started taking out the old trash (called legacy waste) to build a special landfill.
But the company doing the work stopped, and now, tons of new trash keep piling up.
This is risky because the ground could sink, like what happened in another area.
The old trash can also pollute the air and water, potentially making vegetables and fish unsafe to eat.
The city is looking for a new company to clean up the trash, but things are at a standstill.
Mining of legacy waste at Dhapa has been halted for over a year, delaying the landfill project.
The original contractor completed only 37% of the waste removal by July 2024 before the contract was terminated.
KMC is seeking a new firm, but a tender has yet to be issued.
Fresh waste continues to accumulate, increasing the risk of land subsidence and environmental contamination.
The dump site receives waste from multiple municipalities.
