this Shoe Technology Center (Inescope) currently, shoe and her adhesive suppliersin the development of polyurethane adhesives based on the use of 100% renewable sourced raw materials.
Also, given the role that adhesives play in the implementation of the new model, circular economy, necessary Research Regarding the design of adhesive joints in shoes, which facilitates the process of recycle at the end of its useful life, thus allowing the concept “design for recycling”.
In this context, Elda-based Inescop is exploring the development of new adhesives that it has managed to incorporate. successup to 69% by weight polyols of renewable origin, retaining its adhesion properties and durability the same and comply with the technical requirements of durability and durability cutting floor jointtoughest adhesive joint durability in shoes.
fossil resources
Market introduction of adhesives that consume less fossil resources production processes It is accompanied by the study of new adhesive formulations with circularity properties on demand through innovative techniques such as chemical reversibilityamong others.
“This system gives very good results with new adhesives. formulations on an aqueous basis, which is much more environmentally responsible”, notes principal investigator of the Recyglue II project, Alejandra Moyano.
“We’re trying to make it easy with this separation of different materials, responds to external stimuli, in which the separation of adhesive joints occurs. The use of this type of adhesive will facilitate the reintegration of the materials that make up the shoe into the shoe value chain or recover it as renewable resources in other industrial sectors,” emphasizes the researcher.
Research carried out under the Recyglue II project will reduce environmental impact and carbon footprint adhesives, as well as products developed from them, such as shoes. The project aims to improve circularity indicators different types of adhesive polyurethane Employees in the shoe industry.
