With the understanding that packaging alone represents 36% of municipal solid waste in Europe, this report focuses on how and when the reuse of packaging is a better alternative than single-use. This is done by analysing the results of life cycle assessments that compare the environmental impacts of single-use to reusable packaging alternatives. The results demonstrate that the great majority of studies point to reusable packaging as the most environmentally friendly option. The report identifies the packaging types assessed by the various studies and what key aspects, such as the number of cycles or distances and break-even points, favour the environmental success of reusable packaging. It also discusses, in more detail, how specific packaging formats, such as bottles and crates, differ in impacts.
