- Eco-friendly industrial production is essential to save our environment. The present article reviews the sustainability aspects for steel and cement industries, as both are highly demanding. Carbon dioxide emissions from the steel industry can be reduced effectively by carbon sequestration methods. The generation of by-products from steel can be used as raw materials in manufacturing of paints, cement fertilizers etc. The major challenge in cement production is higher input of raw material and fuel in clinker production. These problems can be rectified by adopting suitable co-processing method. Energy requirement can be reduced by using blended cement with highly efficient clinker cooler, dryer, separators, calciner, pre-calciner and waste heat recovery system.
