Why does a color sorter in plastic recycling sometimes reject good material or behave inconsistently? In many cases, the issue is not the machine itself but configuration and operating conditions. This article explains how plastic sorting really works, how compressed air stability affects separation, and what determines consistent performance and production optimization in plastic recycling systems.

In this article, I analyze whether plastic film made from recycled materials can truly resemble products made from virgin resin. I explain the differences between mPCR, cPCR, PCR, and PIR, and how they affect quality, appearance, and compliance. I also discuss current EU regulations on recycling and emphasize the importance of honest communication about post-consumer recycled plastic content. This is a practical overview of plastics recycling technologies and their role in the production of polymers. (Dr. Magdalena Laabs)

Hygroscopicity vs. Osmosis in Plastics – What’s the Difference?

Not all plastics absorb moisture! Hygroscopic plastics (e.g., ABS, PA, PET) pull water into their structure, which can cause defects during processing if not dried properly. Non-hygroscopic plastics (PVC, PE) do not absorb moisture but can act as barriers against osmosis.

💡 Key differences:
✔️ Hygroscopicity – water absorption into plastic granules.
✔️ Osmosis – water passing through a material.
✔️ PVC is not hygroscopic but can reduce osmosis.

Raw material prices seem to be constantly changing, but are these shifts driven by real market dynamics or strategic supplier tactics? Many businesses in the plastics processing and recycling industry have noticed that price announcements don’t always align with actual costs. While some companies still stockpile materials, others now buy only when needed. But is this the right approach? In this article, we analyze pricing trends, common supplier strategies, and how companies can avoid being caught in market manipulation.
