Air Classification
Air Classification is a method used in waste management and recycling to separate different materials based on their weight using air streams. Think of it like a high-tech fan system that sorts light materials (like paper and plastics) from heavy ones (like metals and glass). This process is important in modern recycling facilities to make sorting more efficient and accurate. Similar methods include screening and magnetic separation. These are all part of the mechanical sorting processes that help recycling facilities process large amounts of mixed materials quickly and effectively.
