They are relatively common in low and middle-income country contexts (as well as some high income countries) where their lower operational cost makes them an attractive option for municipalities. With respect to plastics recycling, these systems can be associated with lower recycling rates as householders are required to carry materials separately to the location. In the UK for instance, the recycling of plastics increased considerably as authorities began to collect them from directly from households rather than from communal bins. These schemes have declined over the last few decades, but there has been a recent renewed interest in this approach. For example, the Scottish Government recently announced plans to implement a deposit return scheme for containers.
