The Heavy Picker uses AI-based computer vision and robotic precision to identify and sort valuable metals and minerals from bottom ash fractions that traditional systems often miss. Stone, inert, and hardcore materials pass through, while the system sorts remaining metals and unburnt fractions directly from the belt. By automating these complex tasks, the system enhances efficiency, reduces manual handling, and improves workplace safety.
Capable of performing up to 2,300 picks per hour per arm, the system can handle objects weighing up to 40kg and measuring up to 1.5 metres in size. With the flexibility to deploy as many robotic arms as needed, it delivers up to 99% purity in recovered materials, making it a powerful solution for high-throughput, high-precision sorting in demanding recycling environments.
The Hinwil site, where ZAV Recycling operates, is also home to KEZO, a waste-to-energy facility. The KEZO incineration process produces the bottom ash that ZAV Recycling now processes using advanced AI robotics.
