The process of waste sorting and recycling involves a range of sophisticated technologies and equipment, including air, ballistic, optical, magnetic, and rotary separators. Each of these technologies serves a unique function in the sorting and separation process, and they work together to optimize the efficiency and effectiveness of waste recycling operations.

Air separators, for example, are used to separate lightweight materials such as paper and plastic from heavier materials such as metal and glass. The materials are fed into the separator where a powerful air stream is used to separate them based on weight. Ballistic separators, on the other hand, are used to separate materials based on their size and shape. The materials are fed onto a vibrating conveyor where they are sorted based on size, shape, and weight. This technology is particularly useful for sorting out bulky items such as cardboard boxes and wood.

Optical and magnetic separators are used to sort materials based on their physical properties. Optical sorters use advanced sensors and imaging technology to detect and sort materials based on color, shape, and other characteristics. Magnetic separators, on the other hand, use powerful magnetic fields to separate materials such as steel and iron from other materials. Rotary separators are another important technology in the sorting and recycling process. They are used to separate materials based on their density, and are particularly useful for separating heavy materials such as stone, concrete, and metals. By utilizing these advanced sorting technologies, waste recycling companies are able to recover more valuable materials from the waste stream and minimize the amount of waste that is sent to landfill.
