Massive plant on Haryana border to turn waste into electricity

After  missing several deadlines, Delhi may finally get its biggest waste-to-energy (WTE) plant so far. The North Delhi Municipal Corporation (NMCD) is expecting to officially inaugurate its Narela-Bawana plant, nearing the Haryana border, by the end of November or the beginning of December.

"We are hoping to finally receive an approval letter from the Delhi Pollution Control Committee (DPCC), though trials had begun in July 2016 itself," said YS Mann a spokesperson, from NMCD.

PRODUCE 24-25 MEGAWATTS

 

The plant will process nearly 2,500 metric tonnes of garbage a day and produce 24-25 megawatts of electricity. This will benefit Rohini and Civil Lines areas the most as maximum garbage from here is offloaded at the Narela-Bawana landfill, which is the youngest and only engineered/sanitary landfill in the city.

At present Delhi produces about 9000 MT of solid filth per day. Of this, 1,200 metric tonnes is usurped by the Ghazipur WTE plant generating 12 MW of energy, while the Okhla WTE uses about 1,300 MT of waste producing 1,600 MW of electricity.

The Okhla plant is currently under dispute in the National Green Tribunal (NGT) with residents of Sukhdev Vihar having asked the court for directions to relocate it

RAMKY TO RUN NARELA BAWANA WTE

However, opening of the new Narela-Bawana WTE is not the only good news Delhiites can expect. NMCD officials say that it will be run by the Hyderabad-based company, Ramky, which has been contracted to collect garbage from each household and segregate it as biodegradable and nonbiodegradable, compost the organic matter into manure and then, process only the nonorganic in its WTE plant.

DHALALOS SOON TO BE REDUNDANT

"This is mandatory as per the new Municipal Solid Waste (MSW) Rules, 2016," Mann said. Ramky will also run auto-tippers and tricycles daily, transporting the waste from doorsteps to the landfill, making dhalaos redundant.

"This will take away the problem of foul smell and reduce the number of birds and animals feeding on the overflowing dhalaos," added Mann.

LOSS OF NATURAL FERTILISER, RECYCLABLE MATERIALS 

 The current practice of dumping both the wet and dry waste collectively at WTE plants is much opposed by environmentalists.

This leads to loss of precious natural fertiliser and recyclable materials, scientific think-tanks say.

Besides, Ramky will also operate a 'Leachate Treatment Plant' to detoxify the acidic liquid that leaks from garbage, and has put forth a proposal for an 'RDF (Refuse-Derived-Fuel) to Energy Plant.
