Abstract

Cement production is an energy intensive industry that generates high CO2 emissions which is a greenhouse gas (GHG) causing climate change. Although Egypt permitted cement plants to use coal due to the energy shortage, it has also committed to reducing GHGs emissions considering climate change challenges. Therefore, this research focused on studying mitigation measures of GHG emissions and reducing energy consumption in cement production. A case study has been conducted on Arabian cement plant in Egypt. The fossil fuels (coal, pet coke and natural gas) have been partially substituted with the alternative fuels reaching a rate of 13.83% (agricultural wastes 1.46%, refused derived fuel 10.63%, shredded tires 1.32% and sludge 0.42%). The United Nations approved consolidated methodology (ACM0003) was executed. It was found that the use of alternative fuels reduced the GHG emissions by 107,846.89 tons of CO2e and decreased the consumption of coal by 68,075 tons, and natural gas by 200,120 m3.
Key words: Cement, mitigation, climate change, energy, alternative fuels
