There will be a flat 20p deposit on all eligible plastic and metal drinks containers. These deposits can be retrieved by returning containers to collection points at supermarkets.
The Welsh government want this to be devolved to them: https://exchangeforchange.co.uk/news/welsh-government-decision-on-exchange-for-changes-dmo-application/


Agreed.
I’m sure it used to be a thing in the past too, I remember my grandparents talking about taking bottles back to the shop. Before that my great grandmother used to get milk and orange juice from the milk float, then left the empties out for them to be washed and refilled.
Beer used to be distributed in earthen jugs, which remained brewery property and had to be returned. Same for milk bottles. The idea of buying the packaging as well as the product is fairly new.
An earthen jug of ale is definitely something I can get behind
That was a better scheme. That was only for glass bottles, as they were collected from the stores and reused.
