摘要

With the escalating focus on the global environmental concerns, cement industry is highlighted as one of the largest sources of carbon dioxide (CO2) emissions worldwide. There is a need for exploring mitigation measures to systematically identify, asses, and modify the cement production process CO2 emissions. For that, a framework is designed for the available assessment measures which is inspired by the common literature. The aim of this paper is to evaluate the different performance measures and polices focusing on reducing the carbon footprint of the cement plants. With a comprehensive review of the existing CO2 emission levels globally and focusing on Egypt, this study evaluates the implementation of these mitigation measures for a more environmentally friendly cement industry in Egypt. The study focuses on some technological advancements, fuel and electricity efficient cement plants, and greener alternatives for the reduction. Cement plant in Alexandria is taken as a case study to calculate and compare the results of various combined modifications done on the CO2 emission levels. The essential data were collected from the sustainability reports and the literature with the guidance of the Intergovernmental Panel of Experts on Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories. Moreover, this study can be used for deeper knowledge of the challenges, best practices, and policies that face the reduction of CO2 emissions from cement plants in Egypt. It also projects the findings to see its alignment with the 2030 Net Zero emissions and 2050 climate goals. By applying the reduction measures, the cement plant could reach the 2030 goal as strategically planned. There is a potential of total CO2 emissions reduction of the plant by 22.1% reaching the goal.
