Our key environmental performance indicators include:
materials utilised in our production processes;
amounts of energy consumed and conserved;
water consumed and conserved;
gas emitted and re-used;
biodiversity indicators (such as tree planting); and
waste quantities disposed of, recycled and re-used.
Detailed information concerning our environmental performance will appear in our forthcoming Sustainable Development report. Highlights include:
Our total energy and water use per tonne of product made continues to show improvement:
for the year 2007–08 we had set a target of 5.0% reduction in the specific energy consumption across our operations. The actual reductions were: HZL –13.0%, BALCO –4.0%, KCM –3.0%, MALCO –2.0%;
similarly for the fiscal year against a target reductions of 5–10% in the specific water consumption across various locations the actual reductions were HZL –12.5%,BALCO –10.0% & SIIL –7.0%;
our initiatives to find alternative uses for waste have gathered momentum. For instance MALCO now sends 24.0% of its red mud by-product of alumina production to the cement industry; and
most of our sites have now phased out the use of ozone depleting substances entirely and the remainder will do so within the near future.
