Zusammenfassung:	The method involves providing a processing plant (1) with a main extruder (3). The main extruder comprises a feeding zone (36), and a set of processing zones (37, 39, 41). A set of transfer zones (38, 40) is arranged between the processing zones. A set of side-screw extruders is arranged in the set of transfer zones. Additional plastic material (34) is supplied to a mixture (86). The mixture is homogenized, and the plastic material is fed in a conveyance direction (6) downstream of the processing zones for providing plastic colorant concentrate.
