Chute sorting systems for recycling plastics and glass
Streamline your recycling operations by efficiently sorting and purifying mixed material flows, ensuring high precision contaminant removal with advanced sensor technologies designed to handle high-speed, continuous processing environments.

Separates and Sorts Recycled Plastics and Glass
The FLAKE PURIFIER+ and SPEKTRUM from Sesotec are cutting-edge multi-sensor sorting systems designed specifically for recycling applications. Utilizing a combination of high-resolution CCD cameras, near-infrared sensors, and inductive metal detectors, these systems precisely separate and sort various recycled materials, including PET and HDPE plastic flakes as well as glass fragments. Capable of handling continuous high-speed operations, they are ideal for achieving clean, high-purity end products such as single-colour glass fractions and high-purity PET flakes. The modular design allows for easy integration into existing production lines, with a PLC-controlled system ensuring seamless automation and remote monitoring. Energy-efficient optimization reduces air and electricity consumption, while the robust construction offers durability and minimal maintenance requirements. Fully customizable with multi-sensor configurations, these systems can adapt to a wide range of recycling challenges, ensuring optimal performance and productivity in any facility.
