Waste Plastic Sorting Machines: Advanced Solutions for Modern Recycling

Transforming Plastic Waste into Valuable Resources

As global plastic pollution reaches critical levels, efficient recycling technologies have become essential. Waste plastic sorting machines are revolutionizing how we process mixed plastic streams, enabling higher purity outputs and economically viable recycling operations. This guide explores the cutting-edge systems powering the circular plastic economy.

The Sorting Technology Spectrum

Modern facilities utilize multi-stage processes with specialized equipment:

Core Sorting Technologies

1. Near-Infrared (NIR) Systems

   • Identifies polymers through molecular signatures

   • Accuracy: 95-99% for PET, HDPE, PP

   • Throughput: 2-8 tons/hour

2. Density Separation Units

   • Sink-float tanks: Separates polyolefins (PP/PE) from denser plastics

   • Hydrocyclones: Purifies flakes using centrifugal force

3. Electrostatic Separators

   • Separates mixed plastics through triboelectric charging

   • Critical for PET/PVC separation

4. AI-Powered Robotics

   • 60-80 picks/minute with self-learning capabilities

   • Identifies complex items like multi-layer packaging
