The invention relates to a method and a system for conditioning low-metal waste rich in plastic, which comprises waste from shredder processes that at least partly contains plastic, particularly from end-of-life vehicles. According to the invention, the method comprises the following steps: separating ferromagnetic components (FE) from waste rich in plastic, separating a first raw sand fraction (RS1) from the metal-reduced waste rich in plastic, comminuting the fraction rich in plastic remaining after the separation of the first raw sand fraction (RS1), separating a second raw sand fraction (RS2) after the comminution of the remaining fraction rich in plastic, and separating the remaining fraction rich in plastic into a light fraction (LF) and into a heavy fraction (SF). The system according to the invention comprises the corresponding means for carrying out the individual steps.
