Sorting Systems

Conveyor-based, optical, and robotic sorting equipment for automated classification of recyclable materials by type, colour, and density.

Robotic & Optical Sorting Lines

Automated systems that reduce manual sorting labour and improve material purity at the output stage of material recovery operations.

Robotic conveyor sorter picking recyclable materials
WGS-RCS — robotic conveyor sorting system, up to 3,600 picks/hour per arm
Optical sorter machine classifying plastic types by near-infrared sensor
WGS-OS Series — NIR optical sorter for plastic type classification

Sorting System Models

Available as standalone units or integrated into a complete material recovery facility (MRF) line layout.

Sorting Line Features

Technical design elements that ensure sorting accuracy and operational efficiency in continuous-duty environments.

NIR Spectroscopy

Near-infrared sensor heads identify polymer type regardless of object colour, shape, or surface printing at belt speed.

Precision Air Ejection

High-speed solenoid-actuated nozzle arrays direct compressed air pulses to eject identified items to target fraction chutes.

HMI Control Panel

Touchscreen interface displays real-time sorting throughput, fraction purity estimates, and system alarm status.

Data Logging

Onboard logging of throughput, ejection counts, and material ratios for production reporting and process optimisation.
