The innovation lies in the process. Once the polylaminated material waste is obtained, the technical solutions applied include:
Thorough washing of the waste, cleaning and recovering any residual fibres (cellulose) that will re-enter the market to return to their production cycle or be used for the self-generation of energy.
The product is then shredded to make the waste easier to process and the aluminium size contained in the waste, which can be up to 30 cm x 15 cm, is “managed” thus reducing it to slightly less than 1 mm x 1 mm; allowing it to be dosed in the final recipe, according to its target market/application.
An agglomeration to homogenize the material and prepare it for additivation/blending and extrusion.
An extrusion where, through the heating, additivation and plasticising processes, the formulations are prepared (base material + charge and/or additivation) either for the general market or using a “tailor-made” recipe for a specific customer.
The plant, in this part of the process, ensures optimal mixing of the different recipe components, as well as an extraction of the volatile pollutants which may still be embedded at this point of processing.
