Emissions from Ethiopian clinker-producing cement factories and their impact on community well-being

Abstract

In the realm of cement production, clinker-producing factories emerge as both energy and material-intensive entities, emitting a substantial array of primary pollutants into the environment compared to their non-clinker-producing counterparts. This study investigates the emissions from clinker-producing cement factories in Ethiopia and their impact on community well-being. We specifically focus on particulate matter (PM2.5 and PM10) and gaseous emissions (CO2, N2O, SO2) measured at various units within the cement factories and nearby residential areas. The study area includes major industry players such as Derba Cement plant, National Cement Share Company, Mugher Cement Enterprise, Ethio Cement P.L.C, Dangote Cement plant, Habesha Cement, and Pioneers Cement Share Company. The pollutants were measured using standard instruments, including the portable Aeroqual Series-500 Gas Sensor (S-500) for both particulate matters and gases, with sampling conducted from August 1, 2021, to January 30, 2022. We analyzed the potential health impacts of these emissions, particularly respiratory diseases, among different age groups. The findings underscore the urgent need for regulatory measures to mitigate cement particulate emissions and protect community health. Our study provides valuable insights into the environmental and health risks associated with clinker-producing cement factories in Ethiopia, contributing to the broader field of environmental science.
