'''Recycling''' is processing used [[materials]] ([[waste]]) into new [[products]] to prevent waste of potentially useful materials, reduce the [[consumption]] of fresh raw materials, reduce [[energy]] usage, reduce air [[pollution]] (from incineration) and [[water]] pollution (from landfilling) by reducing the need for "[[conventional]]" waste disposal, and lower [http://en.wikipedia.org/wiki/Greenhouse_gas greenhouse gas] emissions as compared to virgin production.[1][2] Recycling is a key component of modern waste reduction and is the third component of the "''Reduce, Reuse, Recycle''" waste [[hierarchy]].

There are some [http://en.wikipedia.org/wiki/ISO ISO] [[standards]] relating to recycling such as ISO 15270:2008 for plastics waste and [http://en.wikipedia.org/wiki/ISO_14001 ISO 14001:2004] for environmental management control of recycling practice.

Recyclable materials include many kinds of glass, [[paper]], metal, plastic, textiles, and electronics. Although [[similar]] in [[effect]], the [http://en.wikipedia.org/wiki/Composting composting] or other reuse of [http://en.wikipedia.org/wiki/Biodegradable_waste biodegradable waste] – such as [[food]] or [[garden]] waste – is not typically considered recycling. Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials bound for [[manufacturing]].

In the strictest sense, recycling of a [[material]] would produce a fresh supply of the same material—for [[example]], used office paper would be converted into new office [[paper]], or used [http://en.wikipedia.org/wiki/Polystyrene foamed polystyrene] into new polystyrene. However, this is often [[difficult]] or too expensive (compared with producing the same product from raw materials or other sources), so "recycling" of many products or materials involves their reuse in producing [[different]] materials (e.g., [http://en.wikipedia.org/wiki/Paperboard paperboard]) instead. Another form of recycling is the salvage of certain materials from [[complex]] products, either due to their [[intrinsic]] [[value]] (e.g., [http://en.wikipedia.org/wiki/Lead lead] from car batteries, or gold from [[computer]] components), or due to their [[hazardous]] [[nature]] (e.g., removal and reuse of [http://en.wikipedia.org/wiki/Mercury_(element) mercury] from various items). Critics dispute the net [[economic]] and [[environmental]] benefits of recycling over its costs, and suggest that proponents of recycling often make matters worse and suffer from [http://en.wikipedia.org/wiki/Confirmation_bias confirmation bias]. Specifically, critics [[argue]] that the costs and energy used in collection and [[transportation]] detract from (and outweigh) the costs and [[energy]] saved in the production [[process]]; also that the jobs produced by the recycling [[industry]] can be a poor trade for the jobs lost in logging, mining, and other industries associated with virgin production; and that materials such as paper pulp can only be recycled a few times before material degradation prevents further recycling. Proponents of recycling dispute each of these claims, and the [[validity]] of [[arguments]] from both sides has led to enduring [[controversy]].[http://en.wikipedia.org/wiki/Recycling]
