For example, in plants in which colour and natural HDPE are selected an additional valve block is needed to separate these two materials. In addition to the variety of configurations of the optical separators, it is possible to select with one scanner two/three materials running in differentiated streams/channels in the acceleration belt using partitions. This means that there are multichannel optical separators (double/triple channel). For example, an optical separator can be fed a first stream on one channel of the belt, segragating one material from said stream. The rejected waste from this first stream is fed to the other channel, selecting a different material. • Effectiveness. The sorting effectiveness is the percentage of material sorted compared to the amount of sortable material at the unit inlet. Optical separation units have effectiveness rates over 90% (with values of up to 98% measured in light weight packaging sorting plants) if the 6.
