: [[Recycling]] allows us to use less resources [[material]]s from the [[Earth]].: [[Recycling]] makes sure limited resources [[material]]s do not run out.: [[Recycling]] often uses less [[energy]] to make products than [[Extraction|extracting]] resources [[material]]s from the [[Earth]]. ==Key Stage 4=====Meaning===To '''recycle''' is to process waste [[material]]s so they can be used again. ===About Recycling==='''Recycling''' involves several stages:#Collecting and transporting the used [[Product (Business)|product]]s with '''recyclable''' [[material]]s.#Separating a [[Product (Business)|product]] into its separate [[material]]s.#Cleaning the [[material]] to remove contaminants.#Reforming the [[material]], usually by [[melting]] and molding into a block of the [[material]].#Transporting the [[material]] to factories where it can be used to [[manufacture]] a new [[Product (Business)|product]]. : Each stage of '''recycling''' carries an [[energy]] cost. Different [[material]]s require different amounts of [[energy]] to '''recycle'''.The decision to '''recycle''' a [[material]] is based on several considerations:*Can it be collected and transported easily?*Can the [[Product (Business)|product]] be easily separated into its [[material]]s?*Can the [[material]] be '''recycled''' without significant [[impurities]]?*Will the [[property|properties]] of the '''recycled''' [[material]] be good enough for use in another [[Product (Business)|product]]?*Is it cheaper to [[Extraction|extract]] the raw [[material]] than to '''recycle''' old [[material]]s?*Will it take more [[energy]] to '''recycle''' than to [[Extraction|extract]] new raw [[material]]s?  ===References=======AQA==== :[https://www.amazon.co.uk/gp/product/1782945571/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945571&linkCode=as2&tag=nrjc-21&linkId=9e29fad914244909903e5e93f8a01d225 ''Recycling, page 100, GCSE Chemistry;
