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 original state. It is an alternative to "conventional"
waste disposal that can save material and help lower greenhouse
gas emissions. Recycling can prevent the waste of potentially
useful materials and reduce the consumption of fresh raw materials,
thereby reducing: energy usage, air pollution (from incineration),
and water pollution (from landfilling).
