EN1 MATERIALS
USED OTHER THAN WATER
Raw materials are the minerals and semi processed materials
used as inputs in iron and steel making, lubricants are not included in raw materials. The
specific consumption is calculated based on the total tonnage of raw materials divided by
saleable steel production. Reduction in ash content in West Bokaro coal had favourable
impact on specific raw material consumption.

Tubes Division use steel supplied from Steel Works and the
scrap generated from these Units is recycled to Steel Works. Even though Tata Steel is
vertically integrated, material consumed predominantly, in mining operation has not been
considered here. Similarly, other consumables and spares consumed in mining operation have
also not been included here.
| In addition following quantities of
semi-processed materials were also used in the Steel Works. These materials were purchased
from the external sources. • Pig
Iron, 146865 tonnes against 74609 tonnes during 2002-2003.
• Sponge Iron, 303569 tonnes against 270415 tonnes during 2002-2003. |
EN2 WASTES (FROM
EXTERNAL SOURCES) USED
The only waste material from external source that is
sometimes used by Tata Steel is the iron/steel scrap purchased from market for Steel
Melting Shops. During the year 2003-2004, no scrap has been purchased.
