In this context, chemistry plays a keyenabling role, providing the tools and materials needed to replace toxic, fossil-based<br \/>\ncompounds with renewable, safe alternatives. This paper demonstrates how green chemistry can improve the sustainability and resilience of Italian production systems by developing advanced bio-based materials.<br \/>\nThe focus of this study is the development of fully renewable, isocyanate-free polyurethane (NIPU) technology based on the synthesis of flexible foams from soybean oil-derived cyclic carbonates (CSBO). These foams were produced by reacting CSBO and bio-based butanediol bis-cyclic carbonate (BCC) with 1,4-butanediamine using S-alkylation with thiols as a self blowing mechanism. Diatomite, a natural mineral filler, was employed as a nucleating agent.<br \/>\nThe resulting foams have a remarkable bio-based content, matching the morphology of traditional open-cell polyurethane (PU) foams [1].<br \/>\nCrucially, the foams can be reprocessed into flexible films via thermal compression moulding while maintaining their mechanical integrity, thus enabling material circularity [1].<br \/>\nThis research demonstrates how high-performance, recyclable and safe polymers can be produced entirely from renewable materials using green chemistry. This paves the way for<br \/>\nscalable, circular applications that align with the objectives of the EU Green Deal and the restrictions on isocyanates imposed by REACH. This approach provides a compelling model for integrating sustainability into Italian manufacturing processes without compromising on product quality or versatility.<\/p>\n<p>Reference<br \/>\nF.
