Recycling Challenges

Why Mixed Plastic Waste Requires a Specialized Recycling Process

The line has to remove contamination while keeping mixed plastic moving steadily through washing, dewatering and drying.

  • 01

    Variable Composition

    Resin mix changes between batches and directly affects the process route.

  • 02

    Separation Demand

    PE, PP, PET and other fractions must be split before dedicated processing.

  • 03

    Mixed Contamination

    Dirt, labels, metal and organics appear together in the same stream.

  • 04

    Unstable Output Target

    The end product depends on which fractions can be recovered economically.

Output Routes

Choose the Output for Your Recycling Project

  • Route A

    Clean Mixed Plastic 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 mixed plastic 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 Mixed Plastic Recyclers Usually Ask

Can mixed plastic waste be processed without sorting?

Some streams can, but the recovered output is usually limited. Sorting the main fractions normally gives a more valuable result.

Which fractions are worth recovering?

That depends on your local market and the composition of your stream; the assessment is part of the configuration review.

Is a washing stage always required?

If the mixed stream is dirty or carries labels and organics, washing is required before pelletizing.

What should I send before quotation?

Stream composition, contamination type, required capacity and which fractions you want to recover.
