Work on waste-to-energy plant begins at Venkatamangalam
Rs. 100-crore project to be completed by mid-2014; will produce power from solid waste generated in Tambaram and Pallavaram.
Preliminary civil works for a waste-to-energy power plant began at Venkatamangalam village on Monday.
The non-incineration facility will produce power from solid waste generated in Tambaram and Pallavaram municipalities.
A
bhoomi pooja was performed at the 50-acre site at Venkatamangalam,
located around 15 kilometres from Tambaram and coming under
Kattankulathur panchayat union, Kancheepuram district.
The
project is being executed under a public-private partnership on a
design, built, operate and transfer (DBOT) scheme. The Rs. 100-crore
plant, which is scheduled to be completed by mid-2014, is expected to
generate three megawatts of power every hour.K.M.R. Nissar Ahmed,
Pallavaram municipal chairman, said of the total project cost, Rs. 20
crore would be covered by a grant under the Jawaharlal Nehru National
Urban Renewal Mission, while the rest was pooled by Essel Infraprojects,
the lead partner in the project.
The plant would be
designed to handle 300 tonnes of solid waste every day and Essel
Pallavapuram and Tambaram Municipal Solid Waste Private Limited — a
Special Purpose Vehicle created for the purpose — would also be in
charge of operating and maintaining the facility, including landfill
sites, for 20 years, Mr. Ahmed told presspersons here.
The
chairman said, even after the commissioning of the plant, the two
municipalities of Pallavaram and Tambaram would continue to be engaged
in primary collection, and the garbage generated in the two towns will
be transferred to the plant in Venkatamangalam by the private company.
The municipalities would pay Rs. 500 for every tonne of garbage
transferred from the towns to the plant site.
On how
the plant would operate, municipal officials said the garbage brought to
the plant site would be segregated into degradable, recyclable and
other inert waste. The wet waste would be dried with blowers to rid them
of moisture and once that is done, the weight of the garbage would come
down by 50 per cent.
The garbage would then be
sieved, shredded and subject to a thermalisation process which would
finally result in the creation of a syngas. This syngas would be used to
run dynamos and create power supply, which would in turn be used for
running the unit, with the surplus being sold, officials added.
The
waste generated as a by-product could be either used for creating
eco-bricks or dumped in scientific landfills. No part of the process
would result in any form of pollution to land, water or air, the
officials said.
Parthapratim Ata, general manager,
Essel Infraprojects, said they were confident of completing the project
on time and start generating power supply by the middle of next year.
Rochem Green Energy Private Limited would be the technical partner for the project.
