Ethiopia, with a growth rate of 8.5% per year, is one of the 12 fastest growing economies in the world in 2012. Among the main sectors of he economy, agriculture, industry and services contribute 4.9%, 13.6% and 11.1% respectively (Geiger and Moller, 2013). With this growth rate, the country aims to reach the middle economic class in 2025 (Minister, 2011). The Growth and Transformation Plan (GTP) places vital attention on manufacturing sectors as a key driver of economic growth and on the cement manufacturing industry seen as contributing to the success of this plan (Ministér, 2011). Ethiopia's geological features with its large limestone deposit and rapidly growing infrastructure sector with their huge demand for cement provide incentives for cement production and factory expansion in the country (Edwards, 2013). Furthermore, there is a growing need for housing and other construction caused by population growth and growing economic cycles. This situation has favored the creation of new cement factories with a high expansion speed (Amin and Ali, 2010). In the five-year Growth and Transformation Plan (GTP), Ethiopia plans to increase cement production to supply domestic and foreign markets from the initial capacity of 2.7 million tonnes in 2009/10 to 27 million tonnes in 2014 /15 and to reach an annual level of cement per capita consumption of 300 kg (Minister, 2011). The effort of the country's investment agency (2008) in this regard is geared towards promoting access and supply potential of cement raw materials in the country by motivating investors to invest in cement plants by defining opportunities and incentives for investments in concrete. .... half of the paper ......d coal injected into the kiln for clinking and 60% into the calciner for calcination. Various scholars explain in relation to their contribution to pollution; the extraction process generally does not involve significant problems (Van Oss & Padovani, 2002). On the one hand, dust emission sources are kilns, crushers, grinders, clinker kilns and material handling equipment (Kumar and Armani 2012). Furthermore, during the production of clinker or pyroprocess there is a notable source of emissions such as Cement Kiln Dust (CKD), gaseous emissions such as CO2 during calcination and combustion, sulfur oxide, nitrogen oxide and dioxin (Van Oss & Padovani, 2002). Therefore, this study focuses on the two processing units (Fig 1) because they are the main source of impacts. They required multiple energy sources and raw materials, thus releasing pollutants into the surrounding environment during their process.
