Water consumption
Water consumption for the activities of the Group Companies remained virtually stable in 2011 (up 0.9% from 2010). Total consumption stood at around
4.68 million m
3
of water, with 97% of this consumed by the Group's industrial production activities and, more specifically, aluminium production. Of this total
quantity, 96% was drawn from groundwater and 3.9% from the municipal water supply company, with the remaining 0.1% representing rainwater quantities
collected for consumption. The areas from which the Group Companies draw water (especially ALUMINIUM S.A., which has drilled and is using a network of wells
in the area around its plant facilities), do not contain water masses regarded by experts as particularly sensitive because they support a specific endangered
plant or animal species or because they are located in any other area which has been designated as a protected area.

Total consumption of energy from sources outside the Group Companies stood at 20,874.2 Τj. The total use of indirect energy refers to energy which is purchased
and consumed by the Company from non-renewable energy sources and, more specifically, to electricity, natural gas and steam.
In detail:
* The total volume of water recycled/reused by DELPHI-DISTOMON S.A. came from natural separation in the mining site workshops and was used in environmental rehabilitation.
