Environmental Sustainability: Need for Action – BEL Perspective Rajiv Mohan Rao, Bharat Electronics
Environmental Sustainability is the Next Great Challenge in India’s Development Path
Unsustainable resource use • Sustainable Living from Natural Capital • Natural capital • Perpetual– renewed continuously • Solar energy • Renewable – hours to decades • Water, Air, Forest • Area of Concern
WATER RESOURCES 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
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. Water consumption in million ltrs
Electrical Energy consumption Vs Production (Company as a whole) Value of production in crore rupees Electrical energy in lakh KWHrs 10
Specific electrical energy consumption (KWHrs per lakh rupee of production) Company as a whole 1989-90: 2190 Units 2010-11: 88 Units Reduction by 95% 11
Electrical Energy Conservation Energy Consumption (1989-90) : 46.58 Million units Energy Consumption (2010-11) : 29.03 Million units Cumulative Energy savings : 17.55 Million units (From 1989-90 to 2010-11) Reduction in carbon emissions : Equivalent of 16,315 tonnes of CO2 Emission 12
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.
ENERGY CONSERVATION MEASURES • REPLACEMENT WITH ENERGY EFFICIENT SCREW COMPRESSORS • REPLACEMENT WITH ENERGY EFFICIENT CHILLERS • NATURAL DAY LIGHT HARVESTING • PCRA/CII ENERGY AUDIT RECOMMENDATIONS IMPLEMENTATION AND REVIEW

FUTURE PLANS • INTRODUCTION OF SOLAR 40.5 Kwp GRID INTERACTIVE PLANT TO • NEW MANAGEMENT BLOCK BUILDING AT BG.CX • EXPANSION OF LMS & IBMS TO UP COMING / NEW BUILDINGS TO • ENHANCE ENERGY SAVINGS • ESTABLISHING CARBON FOOT PRINTING • LED STREET LIGHTING ENHANCEMENT • LED TO OTHER OFFICE AREAS • FOCUSSING MORE TOWARDS GREEN BUIDING CONSTRUCTION AND • WORK TOWARDS GREEN BUIDING CERTIFICATION
THE WAY AHEAD… • Environmental Sustainability has become the next great challenge along India’s development path. • Environmental institutions are trying to copewith 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.
AWARDS • Rajiv Gandhi memorial national awardfor excellent energy conservation implementation • Lal Bahadur Shastri memorial national awardfor "best energy conservation implementation gold award • Karnataka State award for energy conservation-first position in the general category during 2005-06 • Karnataka State award for energy conservation- in the general category during 2009-10 • CII’s National Award for Excellent Water Efficient Unit-2010 • Certificate of Merit from BEE, Ministry of power during 2011
