Optical sorting

Redwave from Austria specializes in optical sorting of waste. Their sorting technology enables fully automatic separation of recyclable materials and is used with great success around the world. Sorting is done based on color, material type, or chemical composition, using near‑infrared (NIR), sensors, cameras, and XRF technology. Depending on the need, the material is sorted according to various criteria such as plastic recycling, paper, and glass.

Additionally, this technology is used in the mining industry, as well as for the recycling of electronic scrap, vehicles, and wood.

Award‑Winning Optical Sorting

In the autumn of 2020, Redwave won two prestigious awards, demonstrating that they are at the forefront of innovation. Both the Energy Globe Styria Award 2020 and the Energy Globe Austria Award 2020 for plastics were awarded for their efforts to optimize processes in various sorting plants. These processes often involve high costs, and significant resources are frequently wasted without being fully utilized.

This effort resulted in a new innovative and intelligent software called “Mate,” which continuously optimizes the entire sorting process in the plant.
