We care for the Earth DVC
strongly believes that excellence in the environmental
fields is of prime importance. DVC strives to work
with environmental issues in a consistent and systematic
manner.
DVC’s environmental management
programme consists of
- Pollution control at its thermal
power stations and
- Combating soil erosion and soil
decay in order to restore and preserve the quality
of the land.
Pollution Control
Pollutants in the
form of ash and emissions from stack are the major
sources of pollution at coal-based thermal power
stations. In old units, of DVC, at Bokaro, Chandrapura
and Durgapur, which were commissioned, before pollution
control standards became stringent, the following
measures have been taken to bring the pollutants
within the limits:
- Initiation / installation
of ESPs with additional fields to bring down
emission within limits.
- Renovation of de-ashing and
ash handling system.
- Installation of oil and grease
separator.
- Plantation in and around plant
areas, ash disposal areas and outside the project
areas.
Modern units at MTPS, commissioned during 1990s,
comply with latest pollution control norms,
including the provision of reuse and recycling
of maximum affluent to conserve land and water.
DVC’s solid waste management system consists
of evacuation of ash from the ash ponds at BTPS,
CTPS and DTPS, transported in protective manner
and dumped into abandoned open cast coal mines
of CCL, BCCL and ECL respectively. After filling
up of the mines is over, the top surface is
covered with earth of sufficient thickness to
facilitate growth of vegetation.
