This approach makes it possible to identify the most environmentally impactful processes and phases, providing clear guidance on intervention priorities.<\/p>\n<p><strong>When initiating an LCA project, the first step is to identify all the processes involved in each component of a product. For each process, inputs\u2014such as energy, water, and raw materials used\u2014are collected, along with outputs, i.e., emissions to water, air, and soil.<\/strong> Based on the resources consumed and emissions released, the resulting environmental impacts are then calculated, such as greenhouse gas emissions, eutrophication, ozone layer depletion, acidification, and toxicity.<\/p>\n<p>The work carried out by the Politecnico di Torino followed this methodology and structure, resulting in average values that help measure the climate impacts of finished stone random slabs throughout the entire processing chain. <strong>The results are reliable because they are based on data collected directly from quarries and processing facilities. They are also geographically representative, covering materials from several regions not only in Italy but also from other leading countries in the global stone industry.<\/strong><\/p>\n<p>With this global-level LCA, the PNA Business Network aimed to expand its environmental knowledge, create a solid data foundation to inform current and future projects, and lay the groundwork for an Environmental Product Declaration (EPD) certification for stone slabs with a fully Italian supply chain.<\/p>\n<\/div><div class=\"fusion-text fusion-text-2\" style=\"--awb-font-size:20px;--awb-line-height:1.2;--awb-margin-top:45px;--awb-text-font-family:&quot;Montserrat&quot;;--awb-text-font-style:italic;--awb-text-font-weight:700;\"><p class=\"s3\"><span class=\"s7\">Focus interview<br \/>\n<\/span>Giulia Pezzin, Laura Morvidoni, and Isabella Bianco from the Politecnico di Torino, and mining engineer Claudia Chiappino<\/p>\n<\/div><div class=\"fusion-text fusion-text-3\" style=\"--awb-font-size:25px;--awb-line-height:1.2;--awb-text-font-family:&quot;Montserrat&quot;;--awb-text-font-style:normal;--awb-text-font-weight:500;\"><p class=\"s3\">\u201cLCA gave us concrete parameters to act on, enabling true sustainability in the production process.\u201d<\/p>\n<\/div><div class=\"fusion-text fusion-text-4 fusion-text-no-margin\" style=\"--awb-margin-top:15px;--awb-margin-bottom:13px;\"><p class=\"s3\"><span style=\"color: #808080;\"><em><span class=\"s8\">Why was it important to calculate average environmental impact values through the LCA study applied to PNA\u2019s natural stone supply chain?<\/span><\/em><\/span><\/p>\n<\/div><div class=\"fusion-text fusion-text-5\"><p><strong>Claudia Chiappino, Mining Engineer: <\/strong>\u201cTo best represent a sector that brings together quarries of different materials and processing plants using various technologies across the country.
