- Irregular particle size
- fines
- dust and mixed resin conditions.
Recycling Challenges
Why Rigid PE/PP Regrind Requires a Specialized Recycling Process
The line has to remove contamination while keeping rigid pe/pp regrind moving steadily through washing, dewatering and drying.
-
01 Irregular Particle Size
Mixed flake sizes cause unstable feeding and uneven melting.
-
02 Fines & Dust
Fine material has to be managed to avoid losses and feeding problems.
-
03 Mixed Resins
PE and PP fractions may need separation depending on the target output.
-
04 Residual Dirt
Material that is already reduced in size still carries dirt and labels.
Output Routes
Choose the Output for Your Recycling Project
-
Route A Clean Rigid PE/PP Regrind 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 rigid pe/pp regrind 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.

FAQ
Questions Rigid PE/PP Regrind Recyclers Usually Ask
Can the line handle mixed PE and PP regrind?
Yes. The route can either keep the mix together or separate the resins, depending on the target output.
Why is melt filtration important for regrind?
Filtration removes residual fine contamination that washing alone cannot eliminate.
Is washing always necessary?
If regrind comes from a clean in-house stream, washing may be optional and the line can focus on pelletizing.
What should I send before quotation?
Regrind source, resin mix, particle size, required capacity and target output.
