Extracted and Alternative Materials
In 2012, we used 20.3 million metric tons (dry basis) of raw materials for our total cement production. Approximately 6.0% of all raw materials (about 1.2 million metric tons - dry basis) were alternative raw materials, namely by-products and waste disposals from other industries such as fly ash, pyrite ash, blast furnace slag and industrial gypsum. The remaining 19.1 million metric tons (dry basis) were natural materials from mining and quarrying activities.
Compared to 2011, the consumption of alternative raw materials, as total quantity remained unchanged, while as percentage of the total raw material consumed, it has been declined mainly due to the overall reduction of the production of blended cement types.
