Polyurethane is a material that comes in a multitude of forms, from flexible to rigid foams and with very diverse properties. For these reasons, its applications are very varied, and it is used in many sectors.

Today, a large amount of polyurethane waste ends up in landfill, wasting resources. The main reason is that, until now, its recycling has been carried out mechanically, obtaining a material with limited applications due to their properties.

The aim of this webinar is to explain what methods exist for the recycling of polyurethanes, including the most common techniques such as mechanical ones, the chemical recycling which is emerging as an alternative tool that complement the current mechanical recycling to obtain recycled products with high added value, which can be reincorporated both in the same production processes and in other alternative ones, and the newest advances in biological (enzymatic) recycling of this materials. Specifically, we will analyse how to carry out these processes, the classification of the different characterisation techniques that exist for the products obtained, helping to identify the possible applications of the products.
