INESCOP (Footwear Technology Centre)

Biography

Chemical Engineer and PhD in Materials Science, she is currently a senior researcher in the adhesives department within the area of advanced materials and technologies. Her research is focused on the field of sustainable adhesives synthesised from renewable resources such as industrial CO2, vegetable oils, and its characterisation, contributing to their decarbonisation and reducing its carbon footprint.

Her current research focuses on the development of polyurethane adhesives made from lignin polyols obtained from the revalorisation of rice straw and with circularity properties. After the useful life of materials joined, the activation of these adhesives allows the separation of the adhesive joints without damaging or deteriorating the joined components, allowing them to be reused, repaired or recycled.

Presentation Abstract

A novel PU adhesive including reversible- bonds to achieve recycling properties for footwear industry

Eco-design is a key element in facing the challenges posed by circular economy in the footwear sector. In this sense, the role played by adhesives in the product durability and the recycling of shoe components is crucial. Thus, the creation of reversible joints by modifying the adhesives used to join the different materials of a shoe can help recycle them once their useful life is over.

For these reasons, INESCOP, in collaboration with the Institute of Organic Synthesis of the University of Alicante, is working on developing sustainable syntheses towards polyurethane adhesives - one of the most used in the sector - with debonding-on-demand properties through the modification of their polymeric chain by introducing reversible Diels-Alder bonds. This approach reduces the adhesive strength through the application of a thermal stimulus, supporting the rupture of bonds, and thus, facilitating the separation of components for subsequent recycling.
