Life Cycle Inventory of technologies for stone quarrying, cutting and finishing: Contribution to fill data gaps

Italy is among the major producers of dimension stones and a world leader in terms of technologies for stone quarrying, cutting and finishing. In the current context of European Environmental and Raw Material policies, the stone sector is expected to enhance its overall sustainability and circularity. Previous studies have used Life Cycle Assessment (LCA) to evaluate the environmental performance of stone production, along the supply chain. Nevertheless, despite the fairly high level of maturity in terms of methodology, previous LCA studies have highlighted the scarce availability of Life Cycle Inventory (LCI) datasets related to stone sector technologies, which inevitably required the introduction of heavy simplifications. The present paper contributes to fill these gaps by providing detailed LCI datasets of the most common technologies and tools for stone quarrying, cutting and finishing. Datasets have been developed on the basis of primary data provided by three major Italian producers of cutting tools, complemented with secondary data from literature, where necessary. Moreover, modelling parameters have been set to enable the datasets update or their adaptation to specific production chains of the stone or other sectors. “Supplementary Material” provides details on the analysed technologies and on the related datasets (data sources, functional unit, system boundaries, Life Cycle models, parameters and uncertainty). Finally, LCI datasets are provided in file format as well.
