Abstract: In order to achieve a higher material throughput and/or a higher sorting speed in a sorting installation (10) for use in plastics recycling, it is provided, in the case of an apparatus which is intended for separating one or more material fractions from at least one material stream of free-flowing bulk material and which has a directing device (12), via which the material stream is guided under the action of gravitational force, also has an optical sensing device (16) for the spectroscopic detection of composition- or condition-dependent properties of individual fractions (13) contained in the material stream, and additionally has a separation device (14), by which the individual fractions (13) contained in the material stream are separated mechanically in dependence on detection results of the optical sensing device (16).
