This study evaluates the environmental impact of the cement production and its variations between different cement plants, using Life Cycle Impact Assessment. For that purpose, details of the cement production processes are investigated in order to show the respective part of raw materials preparation and clinker production using environmental impacts calculated with CML01 indicators. For the kiln emission data, a European pollutant emission register for French intensive industries is used to quantify the variability of indicators between cement plants. For the CML01 indicators that are controlled by kiln emissions, some of them (i.e. global warming, photochemical oxidation) show variations between cement plants between 20 and 30%, as for other (i.e. acidification, eutrophication, terrestrial ecotoxicity) variations are greater than 40% due to the lack of accurate measurements on both pollutant content and annual flow. Finally, a normalisation, using Western Europe yearly emissions is performed and permits to highlight among all the CML01 indicators which ones are the main impacts for the cement production. Abiotic depletion, global warming, acidification and marine ecotoxicity are the four identified impacts. (C) 2009 Elsevier Ltd. All rights reserved.
