CSIC has published two new scientific articles

40% of plastic production is used in packaging, from which 20% is used in multilayer packaging. This is especially significant if we take into consideration these materials cannot be recycled and end up incinerated or in landfills.

Currently, the routes proposed to solve the recycling problems of multilayer systems can be divided into three main approaches:

• The development of innovative methods to separate the different components.
• The combined processing of all the constituents, which limits to some extent the range of alternatives for posterior applications.
• The ambition to find a monolayer and/or mono-material solutions to substitute the multilayer functions.

Among the possible strategies to achieve sustainability in this sector, MANDALA PROJECT is focused in developing thermo-reversible adhesives that enable an effective delamination and recycling.

In this framework, ICTP-CSIC has recently published two scientific articles: “Designing New Sustainable Polyurethane Adhesives: Influence of the Nature and Content of Diels–Alder Adducts on Their Thermoreversible Behavior” and “The role of molecular architecture on the viscoelastic properties of thermo-reversible polyurethane adhesives “.
