ACC is among the first Indian companies to include commitment to environmental protection as one of its corporate objectives. Long before pollution control norms and regulatory laws came into existence, ACC inducted the use of sophisticated high efficiency pollution control equipment for cement kilns, raw mills, coal mills, power plants and coolers. That was in 1966. Today each ACC factory has high efficiency state-of-the art pollution control equipment and devices. Each of our manufacturing units has a separate Environment Section manned by a qualified environmental engineer and supporting staff. ACC is the industry leader in the urgent race to reduce CO2 emissions. Our performance is seen by independent sources to be best in class. We have established systems and procedures to manage improvements in the control of greenhouse gas and atmospheric emissions.
Energy is a prime concern. We have made significant strides in attaining energy efficiency through our captive power plants and the pursuit of building our capacities in clean renewable energy sources such as wind energy farms
Greening the Environment
Each of our cement plants has its own success story of tree plantation, greening activities, horticulture, flower and fruit cultivation and water conservation. Tree plantation and green belt development programmes have been extended to cover areas in the vicinity of our plants for the benefit of the local community. Afforestation programmes in used mines have helped transform the barren and dry ambience into lush greenery. Tree plantation is a regular and committed activity at ACC. Each One, Plant One is a message that inspires our employees.
With an avowed policy to maintain Zero Water Discharge, we continuously seek better ways to manage our water resources efficiently. The water used in plants for industrial cooling is recycled through cooling towers, water ponds and tanks. Our cement plants have converted old abandoned mines into huge reservoirs by collecting rainwater from catchments around mines. As a result, we have several outstanding examples of achievements in water harvesting and in the creation of reservoirs in abandoned mines and quarries. Some of our plants have become near self-reliant in respect of their water requirements for industrial and domestic consumption.
Transforming and Managing Wastes
ACC has achieved spectacular results in the utilization of two hazardous and pollutant industrial wastes - namely slag from steel plants and fly-ash from thermal power stations - to make blended cements that offer unique advantages to concrete. We were first in the use of waste sludge from the fertiliser industry to make cement. ACC is now actively engaged in the promotion of alternate fuels and raw materials and in co-processing waste materials through effective use of cement kilns. Co-processing is the act of adapting an existing industrial process in a single combined operation whereby ‘waste’ materials generated in other industrial processes may be put to gainful use as alternative fuel or raw materials in cement kilns, dryers and captive power plants. These materials include agro-wastes like rice-husk and other wastes such as plastics, bagasse, lubricants, paints, used tyres, municipal and domestic solid wastes. ACC takes pride in extending its waste management services to a wide range of industries in the country that generate hazardous and non-hazardous wastes.
