sodium hydroxide production at the plant level, developed by DEISO. It captures the integration of upstream resource extraction, fuel combustion processes, energy supply (including US grid electricity), and multi-modal transport systems feeding into intermediate production stages. These stages\u2014comprising sodium chloride processing and combustion-based energy inputs (bituminous coal, natural gas, and residual fuel oil)\u2014are represented as discrete process blocks, each contributing to the final production mix. The diagram highlights the interconnected nature of chemical manufacturing systems and provides a transparent representation of system boundaries, process dependencies, and material-energy flows used in the Life Cycle Assessment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3ff78bb elementor-widget elementor-widget-text-editor\" data-id=\"3ff78bb\" data-element_type=\"widget\" data-e-type=\"widget\" id=\"results\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div style=\"max-width:1200px;margin:0 auto;padding:24px;font-family:Segoe UI,Arial,sans-serif;color:#111827;line-height:1.8;\">\n\n  <h4 style=\"margin:0 0 16px 0;font-size:30px;line-height:1.3;color:#000000;\">\n    Analyse du cycle de vie de la production d\u2019hydroxyde de sodium dans l\u2019industrie chimique\n  <\/h4>\n\n  <p style=\"margin:0 0 22px 0;font-size:16px;color:#4b5563;\">\n    This illustrative case study presents a full Life Cycle Assessment developed by DEISO for the production of sodium hydroxide in the chemical industry.
