RecyclingWikipedia

 · Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its or original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas
