Abstract
The present invention refers to the to the reuse of waste materials based on synthetic resins and, more specifically refers to the reuse of disposable diapers, plastic packaging (PVC, PP, PET, and so on), for the production of raw material for extrusion, lamination, injection and rotational molding processes, among others. The invention consists of a system comprising a chopper, a mill for homogenization of particle size, a disk compactor employing frictional heating between a fixed disk and a rotating disk and cooling means by circulation of cold water inside said discs.

An integrated system for recycling and processing compound materials comprising a material shredder, a particle size homogenizer mill, a friction compactor and a particle cooler, wherein said compactor comprises a disc compactor, cooled by a water circulation arrangement that cools the fixed disc and the rotating disc, comprising, in the fixed disk, an internal chamber where the thermal exchange takes place and, in the rotating disk, a chamber where the thermal exchange occurs, said arrangement comprising a rotating joint comprising a water inlet pipe connected to the chamber of the rotating disc, and a concentric outlet pipe, external to said inlet pipe.
A method for recycling and processing compound materials using, as raw materials disposable diapers, plastic packaging, as well as reduced proportions of non-plastic materials, comprising stages of material selection, fragmentation, mixing, compaction and cooling, wherein said compaction is carried out by friction in a disc compactor, in which a first disc is kept fixed and a second disc moves with a rotation speed in the range of 400 to 500 RPM, more preferably 440 to 450 RPM, wherein all processing steps of the method are dry processes.
