Tata Steel has so far not embarked upon the
use of renewable energy due to the higher
generation cost and low potential of
generation in the areas where it operates.
Energy consumption footprint (i.e.
annualized lifetime energy requirements) of
major products (EN18)This is not
applicable to Tata Steel as the Company
produces steel products only and not
equipment/ appliances that may consume
energy in use. The steel has 100%
recyclability and considered globally as an
environment friendly metal.
Other indirect energy use due to
organizational travel, product life cycle
management, and use of energy-intensive
materials (EN19)
Organizational travel and its impact on
energy use are not captured at present due
to the large size of the organization and
accounting complexities associated with the
same. We do not intend to report on this
indicator in the near future.
Product Life Cycle energy usage is difficult
to capture in the case of steel products.
Iron ore and coal, the major raw materials
used for steel manufacture, are highly
energy intensive due to the presence of high
alumina, silica and phosphorous content in
iron ore and high phosphorous content in
coal. Life Cycle Assessment is carried out
using ECOBILAN TEAM TM Software
on a yearly basis for environmental burdens
associated with steel manufacturing at Tata
Steel (from mining activities to steel
dispatch at the gate of Jamshedpur Factory).
The other energy intensive material used in
the manufacture of steel, oxygen purchased
from M/s. BOC India or M/s. Praxair Plants
located outside the Steel Works at
Jamshedpur. The energy consumed in the
manufacture of oxygen at BOC Plant is not
included in the scope of this report.
WATER
Total Water Use (EN5)
Tata Steel has taken various actions to
optimize its use of water. There is a
increased emphasis on water re-circulation
in all process units. Specific water
consumption (including that for power
generation) is given in Fig.5.14.
Commissioning of 1 MTPA facilities impacted
negatively the trend of specific water
consumption in 2005-06. The entire domestic
consumption of the city of Jamshedpur, that
is 60.26 million m3/annum of water (58.87
million m3 /annum in 04-05), is supplied and
managed by the Company. |
