As a responsible company, Ambuja Cements Ltd. recognises the global pressure on natural resources and lays great emphasis on better material management. Use of alternative raw materials has been made a strategic priority to reduce the consumption of natural resources and extend the life of the quarries. Waste materials such as chemical and marine gypsum are used as additives; fly ash from thermal power plants is used for blending. Low grade limestone, synthetic gypsum waste from other industries and waste materials are used as fuel. A full-fledged testing facility for alternative fuel was commissioned at Ambujanagar. New state-of-the-art storage, pre-processing platforms and feeding systems have been commissioned at our integrated plants to increase the use of alternative fuels and raw materials (AFR).
Our sustainability initiative of increasing the use of AFR,
biomass and fly ash, and reducing that of limestone has lowered our clinker factor. This strategy has helped us
produce over 91% Portland Pozzolana Cement (PPC)
out of our overall production. About 13% of the total raw
material used is recycled input material.
