Research Abstract

Life cycle assessment (LCA) is a useful tool for assessing the environmental impacts of a system, product or service. Cleaner production and pollution prevention opportunities for the cement sector include: 1) use of alternate fuels in cement kilns; 2) NOX reduction; 3) reduction of dust emissions; 4) reuse of bypass dust; and 5) treatment of hazardous waste. Nowadays, Egypt faced energy scarcity inducing political, social and environmental factors putting pressure on the cement industries to obtain their energy from coal instead of the natural gas, solar and mazzut. Therefore, this paper focuses on assessing the environmental impacts of cement producing facilities in Egypt with regard to their environmental compliance if coal is used compared to other sources by using the LCA tool. A comparative analysis among various fuel types of typical cement plant in Egypt is conducted. Results show that the decision of replacing the existing used fuels in cement industry by coal will carry an additional burden on the environment approximately by 20%. Based on a midpoint method, the global warming potential and respiratory inorganics recorded highly negative impacts of 20% and 25% respectively when using the coal compared with other fuels type. Referring to the endpoint method, the damages to human health (DALY) is dominated when using the coal with a relative contribution of 30%. This increased adverse expected damage must be faced from the Egyptian Environmental Affairs Agency (EEAA) by the limitation and constrains of how to control the output emissions from the plant chimney.
