Optical separators

These sort plastic objects by the kind of material: transparent plastic (PET), natural and colored opaque plastic (HDPE) remaining among the rolling waste sorted by the ballistic sorter.

They scan the waste that travels on a belt. Each separator is programmed to identify a type of material. When it identifies an object made of this material, it blows air to separate it from the main belt.
