Title	Circular economy and its implementation in cement industry: A case point in Pakistan
Year	2023
Published
Abstract	The cement industry contributes substantially to world emissions. Sustainable and circular practices are adopted globally to mitigate such emissions. Developing countries like Pakistan lack adaptation to circular and sustainable practices. The study proposes an alternative mix of coal and crop residues that can be used for cement production. The study aims to find the best mixtures of coal with crop residue for combustion purposes in cement industries. The Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA) are implemented for the environmental and economic viability of the proposed material mixtures. Moreover, the study seeks to explore risks associated with the implementation of circular practices in the cement industry of a developing country. The study adopts Modified Safety Improvement Risk Assessment (SIRA) for assessing the risks. The results suggest that the partial replacement of coal with bagasse is the most viable mixture with lower environmental emissions and is economically feasible among other alternate mixtures. In terms of risk assessment, there is a lack of governmental support for adopting circular economy (CE) practices and profit uncertainties of these CE practices.
