Environmental Sustainability: Need for Action – BEL

Perspective

Rajiv Mohan Rao, Bharat Electronics

2

Environmental Sustainability is the Next Great Challenge in India’s Development Path

Environmental Sustainability: Need for Action from Industry

4

Sustainable Living from Natural Capital

• Natural capital

• Perpetual – renewed continuously– Solar energy

• Renewable – hours to decades– Water, Air, Forest

Area of Concern

Unsustainable resource use

WATER RESOURCES

• Limited availability of Potable Water

• Shrinking Ground water table: Bore wells

drying up!

• Recycling Water: Need to use for gardening &

horticulture

• Rain water harvesting to retrieve water

• BWSSB tertiary treated water

WATER RESOURCES

ADOPTION OF NEW TECHNOLOGY BY THE INDUSTRY REQUIRING (LESS WATER PER UNIT

OF PRODUCTION) Replacement of natural draft cooling towers by induced draft cooling towers resulting in water conservation of about 1500M/year.Replacement of conventional air cooling system (water spray) by CELDEK cooling pads resulting in water conservation of about 2500 M/year.Switching over to waterless (Non flushing) urinals in a phased manner.Installation of auto level control switches in sumps and overhead tanks.

Water conservation Reduction in potable

water consumption28% in last 9 years

Conserving 40% of potable water annually by recycling

No waste water is discharged outside. Makes Bangalore Complex a Zero Discharge Unit.

Management Approval

Conservation of fresh water by use of treated wastewater

BEL has an agreement with M/s Bangalore Water Supply and Sewerage Board to buy one million Litres of water everyday from their sewage treatment plant. As such we are buying the tertiary treated sewage from the BWS&SB, Yelahanka sewage treatment plant. This will in turn save one million Litres of water every day which will be indirectly available to the community at large.

• Environmental Sustainability has become the next great challenge along India’s development path.

• Environmental institutions are trying to cope with increasing pressures of rapid growth. Public demand for cleaner environment has been a challenging task.

• Impressive initiatives in Environmental Awakening and good practice by various players are being adopted. The priority is to scale up these good practices across the country and reverse environmental degradation.
