3. Conclusion Cement industry being a contributor to Green House Gases and Carbon emissions there is a pressing priority to work on the reduction of carbon footprints to ensure Sustainable development. In addition to the reduction in carbon emissions, reducing clinker-to-cement ratio and using blended cement will improve the quality and long term performance of concrete. Improvement of concrete performance and structural durability leads to less repair work and renovation/new construction which saves cement and construction raw materials along with other related limited resources. CCUS, WHRS, and Coprocessing form a part of major technology oriented approach and open doors for further optimized innovations that help the unwanted or polluting products generated during the cement manufacturing process or from any other industry to be recycled and reused. Adopting Circular Economy by organizations is important to achieve sustainable development and make this earth a greener place. Adopting this approach shall immensely help in reducing wastage and landfill dumps which shall also help in making the earth a clean place. 4.
