What Is Friction Washing in Plastic Recycling?

In recycling lines, friction washing is used to remove fine and stubborn contaminants such as labels, oils, sand, and organic residues — beyond what basic rinsing can handle.

How It Works
A high-speed rotor creates mechanical scrubbing, while water flow flushes out impurities. This combination delivers cleaner flakes with reduced odor and residue.

Why It Matters
High-quality washing is crucial for downstream processes such as Pelletizing, Filtration, Compounding, and Food-grade upgrading

Better washing means:
Higher output value
Lower wear on extrusion equipment
More stable pelletizing
Better compatibility for rPET & rPE applications

In short, no clean washing, no true recycling value.
