Sustainable options for paints through a life cycle assessment method

Abstract In recent years, the paint industry has addressed development of products, technologies, and packaging to build conditions improve environmental performance in accordance circular economy goals. For these reasons, a life cycle thinking approach allows for understanding most important steps pursuing closed-loop strategies related This paper provides twofold analysis: first, comparison two paints, characterised by different chemical compositions, been carried out according current production (baseline scenario); second, each product, additional alternative scenarios have hypothesised. These focus on use waste blended with virgin paint, high rate recycled inputs materials. The aim is first assess impacts cycles paints identify feasible measures reduce impacts. second choose better option between scenarios, approach. results highlight that supply raw materials greatest impact both all indicators. Consequently reduces roughly 48%, average. Furthermore, options allow us determine 50% polypropylene had than 100% aluminium, although contribution negligible total Confirming results, sensitivity analysis undertaken.
