Optical Sorting
Optical sorting is a modern technology used in recycling and waste management facilities to automatically separate different types of materials. It uses cameras and sensors, similar to very advanced scanners, to identify and sort items by their color, shape, or material type. Think of it like an automated quality control system that can process thousands of items per hour, making recycling operations faster and more accurate than manual sorting. This technology is becoming increasingly important as recycling facilities aim to process more materials with greater accuracy and efficiency.
