Makers of sorting equipment and metal-detection technologies are upgrading their products to meet recyclers' demands for purer material streams. Tomra Tomra is touting its work in adding artificial intelligence to its high-precision Autosort flake-sorting equipment with an add-on called Gain. The company said Gain can quickly adapt to new waste streams and increases sorting effectiveness. Tomra demonstrated Gain at Ecomondo, an Italian show for green technology in November, on its AutoSort system. AutoSort has a conveyor belt that carries material past sensors and cameras that identify colors and textures. It can handle a variety of waste streams and objects, including packaging, mixed plastics and commercial and industrial waste. Gain enhances existing sortation systems, Tomra said. It classifies objects based on camera data.
