Cement life cycle assessment : case study of an integrated industry in Madagascar

Year: 2024

Type: article

Abstract: The cement industry is upstream from many sectors and contributes to greenhouse gases emissions for all buildings and civil works life cycle.To reduce the emissions, it's necessary to have the right situation about it.The aim of this studyis to estimate the greenhouse gases emission factors of the cements produced in Madagascar.For this, Life Cycle Assessment, an environmental evaluation's key tool, normalized by ISO 14040 to ISO 14044 is chosen.The study of two types of cement manufactured by an integrated plant is carried out from the raw materials extraction to the production phase.Greenhouse gases emission factor of 1.29 t CO2 eq is associated to one ton of clinker, generating 0.877 t CO2eq per ton of CEM II/B-P 22.5 and 1.122 t CO2eq per ton of CEM II/A-P 32.5 UT-PM.The results can provide a baseline for greenhousegases emission factors of cement in Madagascar and can be used for environmental impact assessment of concrete and cement based-materials.
