Abstract: A waste sorting system (1) comprising a tank (S) for collecting recyclable material (RM) and a sorting unit (U) comprising a first sorting station (10) connected to the tank (S) through a transport device (12) of the recyclable material and a first sorting basin (14) containing a first liquid solution (L1) of given density to separate, according to Archimedes' principle, the recyclable material (RM) into a first material phase (F1) of first selection and a second material phase (F2) of first submersion; the first sorting basin (14) is delimited at the bottom by a first lower collection portion (140), the sorting unit (U) comprising first scraper means (16) associated with the first sorting basin (14) for collecting the first phase (F1) from a free surface of the first liquid solution (L1) and first wash means (18) of this first phase (F1); the first lower collection portion (140) being passed through by a first conveyor (11).

Abstract: Compactor (100) for the “granulation” of plastic materials, the compactor (100) comprising a first zone or unit (101) for loading and distribution capable of being loaded with plastic material and distributing the plastic material loaded to other zones and/or units of the compactor (100); a second zone or unit (104) comprising a perforated spinneret (110) and at least one compacting roller (105) installed external to the spinneret (110), where the material is “granulated” by “sinterization” deriving from its forced passage through the perforations of the spinneret (110) under the action of the at least one roller (105); a third zone or unit for the forced feeding of the material, being provided at the at least one roller (105) comprising at least one rotating feeder auger (111) housed at least partially in a tubular housing (113).
