The alternatives that could potentially replace them from a environmental impact of single-use plastic bottles has been functional and transportation point of view. The following widely discussed in society. For example, they are among alternatives are considered: glass bottle (single-use), the top plastic products found on beaches, contributing to aluminium can (single-use), carton laminated packaging the growing littering of marine and terrestrial ecosystems. systems (single-use), reusable steel and aluminium bottles, To mitigate the environmental problems of single-use as well as non-container means for providing drinking water plastic bottles, there is a need to consider alternative (see table below). Reusable glass bottles were considered in solutions. This report summarises current knowledge about one study only as part of sensitivity analysis. the environmental performance of single-use plastic bottles and their alternatives, and analysis how this knowledge can The report includes a meta-analysis of seven life cycle be used to guide policy makers and other actors. assessment (LCA) publications, see below table.
