means The process of collecting and reprocessing used materials so they can be made into new products instead of being thrown away.

from The root word cycle traces back to Greek kyklos, meaning circle or wheel — the shape of something returning to where it started. 'Recycle' bolted on the Latin prefix re- ('again') sometime in the mid-20th century, first in technical and industrial contexts describing the reuse of materials in manufacturing processes. It only became a household word alongside the rise of environmental movements in the 1960s and 70s, when the circle stopped being an engineer's term and became a civic ritual.
