After the separation phase, we undertake a critical formulation and granulation stage to transform the sorted material into ready-to-use resources. By heating the polymers to more than 200°C and by integrating specific additives (glass fibers, antioxidants, pigments), we restore the initial technical specifications (shock resistance, thermal stability, colorimetry). This advanced know-how, which makes it possible to produce grades “on demand”, is protected by 5 patents currently being filed.
