01 / SORTING
Colour sorting
We assess different families of shredded plastics and any target colour, considering shade and appearance and subject to the material’s technical suitability.

Advanced sorting of shredded plastics by colour and polymer
A mixture of shredded plastics can limit the material’s value and commercial outlets. Sorting it by colour, polymer or both can produce more homogeneous fractions, with greater value potential and new possible applications.
At SORTPLAST, we develop solutions based on advanced technology to help companies in the recycling industry recover value from their materials.

Barcelona · Spain01 / WHAT WE DO
From one mixture to separate fractions
SORTPLAST develops solutions for sorting shredded plastics by colour, polymer or a combination of both.
Each material is assessed individually to determine the most appropriate separation strategy.
02 / SORTING
Polymer sorting
Separation of mixtures by polymer type, always subject to technical assessment and validation.
- HDPE
- PP
- PS
- ABS
03 / SORTING
Combined sorting
Several stages to obtain fractions by colour and polymer. The process sequence is defined after the material has been assessed.
Colour + polymerA strategy for each material
Explore combined sortingThe feasibility of a separation and the results achievable depend on the material’s actual characteristics and must be validated technically.

You supply the material.
We carry out the sorting.
SORTPLAST provides an industrial toll sorting service. The customer retains ownership of the material before and after sorting, including all resulting fractions.
03 / MATERIALS
Materials we specialise in
Our specialisation in HDPE, PP, PS and ABS relates particularly to polymer identification and sorting. Separation feasibility must be assessed technically for each material.
HDPE
High-density polyethylene
PP
Polypropylene
PS
Polystyrene
ABS
Acrylonitrile butadiene styrene
Working with another material?
We can also assess enquiries relating to:
LDPE · PET · PVC · POM · PC · PA · PMMA · PBT
and other engineering plastics.
For colour sorting projects, we can assess other families of shredded plastics. Tell us about your material and the colour fractions you need to obtain.

05 / HOW WE WORK
Every material requires a different strategy
- 01
Understand the material
We establish its origin, composition and characteristics.
- 02
Define the target fractions
We clarify what you need to separate.
- 03
Assess feasibility
We examine the sorting options.
- 04
Define the process
We develop a strategy for that material.
- 05
Carry out sorting
We apply the process agreed in advance.
- 06
Obtain the separate fractions
The sorted material remains yours.
An enquiry sets out the customer’s objective. Feasibility and service conditions are confirmed subsequently through technical assessment.
06 / TECHNOLOGY
Technology applied to sorting
Colour sorting
High-resolution industrial cameras, controlled lighting and image processing enable the visual characteristics of particles to be analysed.
When the system identifies a particle that needs to be separated, high-speed pneumatic ejection systems may be used to direct it into the appropriate fraction.
Polymer sorting
Certain polymers can be separated using spectral detection technologies such as near-infrared — NIR — and other techniques suited to each application.
Different materials exhibit characteristic spectral responses that can be used for identification and subsequent separation.
