Granulation
Granulation is a common process in recycling where large materials are broken down into smaller, uniform pieces (called granules). Think of it like turning big chunks of plastic, rubber, or other materials into small, consistent pellets - similar to turning ice cubes into crushed ice. This process is essential in recycling because these smaller pieces are easier to sort, clean, store, and reuse in making new products. When companies mention granulation in job descriptions, they're usually talking about operating or maintaining the machines (granulators) that do this work.
