Plastic Sorting Separating System Recycling Solution
Plastic Sorting Separating System Recycling Solution
Sorting and separation solutions that split a mixed plastic stream into defined single-material fractions before washing, pelletizing or sale.
Material Scope
Plastic Sorting Separating System Materials We Process
One representative feedstock image, then a compact material list for faster scanning.
Material forms
- Mixed rigid plastics, mixed bottle streams, film and rigid mixtures, and streams carrying metal, labels or unwanted polymers.
Common contamination
- Mixed polymers, metal, labels, stones and heavy matter, with composition that varies between deliveries.
- Mixed polymers
- metal
- labels
- stones and heavy matter
- with composition that varies between deliveries.
Recycling Challenges
Why Plastic Sorting Separating System Requires a Specialized Recycling Process
The line has to remove contamination while keeping sorting & separating moving steadily through washing, dewatering and drying.
-
01 Mixed Polymers
Different resins have to be identified and split before washing or extrusion.
-
02 Metal Contamination
Ferrous and non-ferrous metal must come out early to protect crushers and extruders.
-
03 Heavy Matter & Stones
Sand, glass and stone increase wear and contaminate the sorted fraction.
-
04 Variable Feed
Composition changes between deliveries, so the route has to tolerate variation.
Output Routes
Choose the Output for Your Recycling Project
-
Route A Clean Sorting & Separating Flakes
Washed and dried flakes for in-house processing, separate pelletizing or sale as prepared recycled material.
- Size reduction and washing
- Separation and dewatering
- Drying to a stable flake condition
-
Route B Recycled Pellets
A continuous route from contaminated sorting & separating to filtered recycled pellets for suitable downstream applications.
- Washing line matched with extrusion
- Degassing and melt filtration
- Pellet cooling, storage and handling
Output specification depends on the incoming material and the target application.
Process Route

Recommended Systems
A Recycling System Configured Around Your Material
Retech does not treat every sorting & separating project as the same package. The line is developed around actual feedstock, contamination, required capacity, target output and site utilities.
Plastic Sorting & Separating System
For customers who need a defined single-material fraction before washing, pelletizing or sale.
- Receiving, pre-sorting and metal removal ahead of size reduction
- Density separation to split the stream into fractions
- Label and light-fraction removal before the sorted material leaves the line
Sorting Line with Metal & Label Removal
For streams that carry metal and labels which have to be taken out before downstream processing.
- Overband iron remover and metal detector working together
- Zig-zag label separator for the light fraction
- Quality check on the sorted fraction before storage

FAQ
Questions Sorting & Separating Recyclers Usually Ask
What decides the sorting route?
The stream composition, the target fraction and the purity the next process step requires.
Can one line handle different plastics?
Yes, but the practical range is defined during configuration — mixing incompatible polymers normally needs a dedicated separation stage.
How is metal removed?
An overband iron remover and a metal detector can work together to take ferrous and non-ferrous metal out of the stream.
What should I send before quotation?
Stream composition, contamination type, target fractions, required capacity and site conditions.
