Combined sorting
When one separation is not enough
Some streams contain different polymers, colours and other fractions together, making a multi-stage process necessary.

The actual sorting sequence depends on each material and is defined after its technical assessment.
When a multi-stage process may be needed
- When a stream contains different polymers and colours.
- When the objective requires several distinct fractions.
- When successive sorting decisions are needed to achieve the intended objective.
The stages do not necessarily follow a polymer-then-colour sequence. The sequence is defined for each material after assessment.
