Recycling is the process of taking an otherwise-discarded item or material and cleaning, sorting, and breaking it down into its basic form (such as fibers or pellets). This material is then used to produce new items. Recycling keeps useful materials from being discarded in landfills, prevents resource extraction due to the creation of new materials, and provides a new life for used items. Recycling can utilize both pre-consumer waste (materials left over from production) or post-consumer materials (used clothing, empty water bottles, etc).
