48 Figure 3: Product Life Cycle Assessment In the present world, circular economy is the buzzword where the products and waste materials are reused, refurbished, and recycled with significant economic and environmental benefits. Figure 3 depicts product Life Cycle Assessment. Government intervention has an important role in developing the circular economy and increasing a lifecycle prospective by taking economic actions, in particular government can use variety of innovative policy tools both fiscal and non- fiscal. The philosophy of the circular economy is linked to the promotion of resource efficiency, taking into count the full lifecycle of cement and concrete from initial planning and manufacturing of cement and construction products to finally the building demolition and waste treatment and disposal. Improving the resource efficiency throughout the lifecycle of building will make construction sector more competitive. In the Circular economy government program to stimulate and support the transition towards a circular economy, the construction and demolition waste sector was defined as one of the five priority sectors for a more vibrant circular economy. In volume, construction is the biggest source of waste in any country and almost 90% can be revalorized. Future advances of LCA in enhancing regional detail and accuracy as well as broadening the assessment to economic and social aspects will make it more relevant for producers and consumers alike. Shifting to a circular model means changing our linear economy’s supply logic. Cement industry will need more renewable energy, more biowaste materials (Agro based wastes). This is the critical supply side of the circular economy. But efficient resource use is not the main business driver in a circular model – a common misconception. The true power lies on the availability of right quantity and quality of waste / alternate fuel / raw materials for cement industry. The key to an Aatmanirbhar Bharat is sustainable growth. The need of the hour is a development model that leads to the optimum utilization of resources. With a growing population, rapid urbanization, climate change and environmental pollution, India must move towards a circular economy very fast. The Government has been actively formulating policies and promoting projects to drive the country towards a circular economy. It has already notified various rules, such as the Plastic Waste Management Rules, e-Waste Management Rules, Construction and Demolition Waste Management Rules, Metals Recycling Policy, etc in this regard. However, there are plenty of low hanging fruits, which can be reached jointly by combining LCA and CE for better sustainable Cement Industry. The circular economy encompasses a very large number of sectors of activity and can be broken down into seven complementary patterns of production and consumption which, when combined, make sense, and reinforce each other: Figure 4 shows Implementation of CE by various • Sustainable Procurement: A responsible purchasing policy • Eco-Design: Reduction of environmental impacts of a product • Industrial Ecology: Industrial Synergies–one’s waste to another’s resources Circular Economy Principles
