[[Glass]] is defined as 'a hard, transparent material, used to make windows, bottles, and other objects'<ref>Cambridge Dictionary, 2019.

It is formed from a melt by cooling to rigidity without crystallization and is a usually transparent or translucent material consisting typically of a mixture of silicates'<ref>Marriam-Webster, 2019. [https://www.merriam-webster.com/dictionary/glass Definition of GLASS. Merriam-webster.com.] [online] [Accessed 5 Dec. 2019].</ref>. Crushed glass for [[Recycling|recycling]] is known as [[Cullet]]. | |||

[[Glass]] is a resource that can be continuously recycled without a decline in quality. The four main constituents of glass are sand, soda ash, limestone and other additives for colour or special treatments, these materials are not in shortage but the quarrying required to obtain them is energy-intensive and has consequential environmental impacts<ref name="foo">Recyclenow, 2019.

Glass is collected by local authorities and waste collection businesses as either a separate stream or as a mixed stream with [[Dry Recyclables]] for subsequent sorting at a suitable [[MRF]] (although this is increasingly being seen as an impediment to the quality of the other [[Dry Recyclables]] as glass breaks and contaminates them). | Glass is collected by local authorities and waste collection businesses as either a separate stream or as a mixed stream with [[Dry Recyclables]] for subsequent sorting at a suitable [[MRF]] (although this is increasingly being seen as an impediment to the quality of the other [[Dry Recyclables]] as glass breaks and contaminates them). | ||
