This recycling level will further improve as the industry continues to promote recycling towards local authorities and the waste management sector and demonstrates via its national projects and initiatives that collection, sorting and recycling of even small items, such as closures, can be improved. Depending on the national collection and recycling schemes in Europe, aluminium closures are collected either in mixed packaging fractions or together with glass packaging. In some countries (e.g. Germany) the collection and recycling rates are above 85%.
Aluminium closures collected together with glass packaging (e.g. bottles, jars, etc.) are completely separated from the glass fraction during the glass recycling process. This is due to the production requirements in glass recycling as well as for economic reasons. Subsequently the separated aluminium closures go into the aluminium material recycling for re-melting to be used again for other valuable aluminium product.
