6. LCA: InterpretationA1-A3 are the modules with the majority of the impacts. Overall, most of the impact categories are dominated by energy processes and raw materials consumption for ceramic mixtures. Global warming potential (GWP), into A1-A3 modules, is generated by energy process for 70% and by raw materials for 18%. Energetic consumption impact also on abiotic fossil depletion (ADPEf) for about 61%. The ozone layer depletion (ODP) is driven by the raw materials extraction for 37%, 33% by energy (mainly electricity) and 16% by the glazes. Eutrophication potential (EP) is distributed between energy consumption (20%) and extraction of raw material (13%), transport (14%) but also direct emission due to an atomize process for about 8%. Production of glazes and colorants for mixture results important for depletion of abiotic elements (ADPe) respectively for 84% and 9%, due to the production of natural elements like oxides of zinc, aluminum and lead. Energy results are also important for POCP (46%).
