Sorting systems.
 
 
Sorting is becoming more and more important.

90% of the world goes with manual sorting, and this is still fine when throughput stays under a certain level.

Sorting machines have been specialised for plastics sorting with different methods giving really good results.
 
On the other side, the cost of such device is still high and, unless you're looking for a first class pellet to be sold for technical application, you may want to stick to manual.
