Quality and Consistency of Output - Plastic Recycling

2023-05-12 | Technical Blog | By Janine Cheng |

High-quality final pellets coming from well-prepared input material and a well-controlled recycling process is a matter of course. In other words, recycled materials without proper preworks and a recycling process without inspections will not bring you plastic pellets which meet the market standards.

This article aims to help you identify any crucial missing elements in your plastic recycling process and provide suggestions to improve your recycling business.

Why is “consistency” important in plastic recycling?

Consistency is crucial throughout the plastic recycling process, from the quality of the input material to the processing conditions and the output quality of the recycled pellets. Maintaining consistency in these areas helps ensure the efficiency of the recycling process and increases the marketability of the final product.

Tips for the consistent quality of plastic recycling

  • Adequate preparation

    To obtain high-quality final pellets, it is essential to ensure that the input material is of the same quality. This means sorting, washing, drying, and crushing should be done to the highest standard.

  • Material testing

    Testing before full-scale manufacturing allows for the examination of the material's purity, properties, and shape, as well as for identifying any problems with the recycling machine's operation. It is crucial to monitor the consistency of the output quality and adjust parameters if necessary.

  • Regular inspections and continuous improvements

    Consistent quality of the recycling process can be maintained by regularly inspecting the process to identify potential or existing problems, ensuring a smooth procedure. Additionally, reviewing and identifying areas for improvement can help enhance the process further.

Ideal plastic recycling process includes well-processed plastics and regular inspections.

How to take plastic recycling to the next level?

  • Integrated plastic recycling technology

    The most ideal situation is to produce consistent quality pellets with the least space, costs, and effort.

    POLYSTAR’s plastic recycling lines integrate cutting/shredding, extrusion, and pelletizing into one machine, making recycling more convenient and cost-saving. Additionally, feeding, degassing, and filtration systems enhance stability and efficiency, ensuring output quality consistency.

  • The awareness of the latest trends

    To remain competitive, it's crucial to stay informed about the latest trends and innovations in the industry. This can be achieved through attending plastic trade fairs, following industry leaders, monitoring your competitors, and other approaches.


Consistency plays an important role in plastic recycling, from the quality of the recycled material to the output plastic pellets. It can be achieved by proper material preparation, regular process inspections and optimizations. If you would like to improve more, in addition to being aware of the new trends, consider upgrading your plastic recycling technologies.
