An exhaustive study of the influence of ceramic glass material composition on the environmental impact has been performed. In order to perform a more accurate calculation of the environmental impact a life cycle assessment (LCA) was implemented using real material composition of ceramic glasses. Employing a sequential X-rays Fluorescence spectrometer, the composition of several ceramic glasses were analyzed, as this information is not published by the manufacturers. The environmental impact results of each ceramic glass were surveyed using EcoInvent v3.4 data, and SimaPro 8.4 software, following ReCiPe Endpoint and Carbon Footprint methodologies. The importance of considering the composition on the LCA is shown, establishing significant differences among the analyzed glasses. Few variations in the quantity of material composition generate high differences on the environmental impact values, demonstrating the high influence of the material composition on the environmental impact. Elements such as tin, lithium, and titanium are the ones that generate the highest contribution on the environmental impact. In contrast, silica sand shows the lowest impact in both methodologies despite it supposes between 58% and 63% of their compositions. Others such as barite and magnesium, together with neodymium emerged in the composition of the studied ceramic glasses as they are considered Critical Raw Materials by the European Union, due to their supply risk and economic importance.

材料成分对陶瓷玻璃环境影响的影响

已经对陶瓷玻璃材料组成对环境影响的影响进行了详尽的研究。为了更准确地计算环境影响，使用陶瓷玻璃的真实材料成分实施了生命周期评估（LCA）。由于制造商未发布此信息，因此使用连续X射线荧光光谱仪分析了几种陶瓷玻璃的成分。遵循ReCiPe端点和碳足迹方法，使用EcoInvent v3.4数据和SimaPro 8.4软件对每种陶瓷玻璃的环境影响结果进行了调查。显示了在LCA上考虑组成的重要性，从而在分析的眼镜之间建立了显着差异。材料成分的数量变化很少，不会对环境影响值产生很大差异，这表明材料成分对环境影响的影响很大。锡，锂和钛等元素是对环境影响最大的元素。相比之下，硅砂尽管在其组成中占58％至63％，但在这两种方法中影响最小。由于其供应风险和经济重要性，被研究的陶瓷玻璃的成分中还出现了其他元素，例如重晶石和镁以及钕，因为它们被欧盟视为关键原料。锂和钛是对环境影响最大的元素。相比之下，硅砂尽管在其组成中占58％至63％，但在这两种方法中影响最小。由于其供应风险和经济重要性，被研究的陶瓷玻璃的成分中还出现了其他元素，例如重晶石和镁以及钕，因为它们被欧盟视为关键原料。锂和钛是对环境影响最大的元素。相比之下，硅砂尽管在其组成中占58％至63％，但在这两种方法中影响最小。由于其供应风险和经济重要性，被研究的陶瓷玻璃的成分中还出现了其他元素，例如重晶石和镁以及钕，因为它们被欧盟视为关键原料。
