What Happens Inside a PET Hot Washer? (Temperature, Chemistry & Friction)
Ever wonder how a dirty soda bottle actually becomes clean enough to be recycled?
It’s not just soap and water. In a PET washing line, the magic happens inside the Hot Washer.
Here’s the breakdown of the process:
The Heat: We crank the temperature to 85–95°C. Cold water won't cut it if you want to remove adhesives.
The Chemistry: We use a controlled amount of Caustic Soda (NaOH). This breaks down the glues and organic residues that stick to the plastic flakes.
The Physics: High-speed paddles create turbulence. This friction scrubs the surface of every single flake.
The Result?
Clean, low-contamination PET flakes ready for the next stage of the recycling process.
It’s basically a high-tech spa treatment for plastic. 🧪♻️
