Abstract (en)

[origin: WO2021245352A1] The invention relates to a method for recycling a polymer foam comprising the following steps: a) laminating the polymer foam in the presence of at least one polymeric binder in order to obtain a homogeneous mixture of the laminated polymer foam and said binder, b) recovering the homogeneous mixture of the laminated polymer foam and the polymeric binder in the form of strips, and c) breaking said strips up into fragments of a material that can be used as a raw material, as well as the material obtained and the uses thereof.
