Sorting of Plastics by Near-Infrared-Detection

These can only be met if recycling also includes the plastics contained in these appliances. A reliable, automatic identification of the various kinds of synthetic materials is a prerequisite for later material recycling. Therefore, a comprehensive study shows the expected amounts of old appliances in the five statutory categories, and we estimate the resulting sorts and quantities of plastics therein. For refuse groups 3 and 5 there is still need for action concerning the recycling of plastics. Particularly the synthetics of group 3 are estimated to be highly polluted by flame-retardants.
