Sensor-based and Robot Sorting Processes and their Role in Achieving European Recycling Goals - A Review

A circular economy is the stated aim of current technological and political developments in waste management sector. Achieving goal a requires significant improvements treatment technologies. For this reason, paper summarises relevant technologies, detailing sensor-based sorting This review analyses key spectral analysis methods like Near-Infrared Spectroscopy, Visual X-ray transmission, fluorescence Laser-Induced Breakdown Spectroscopy. study further contains detailed standard construction types chute sorter, belt sorter robot-aided sorting. Further insights branch are permitted by describing players stakeholders sorting, area expertise fields for primary sensor machine suppliers. convenient lookup table capabilities these suppliers provided. The last chapter trends digitalisation Industry 4.0 recycling sector, elaborating on technology digital management, robots smart villages recyclable materials scanners. reviewed data portrays industry’s substantial developments. While new learning, convolutional neural networks robot increasingly implemented, discrepancy exists between State-of-the-Art.
