There is a significant burden associated with disposing of the supermarket carton (refuse collection, landfill sites etc). However, the cost of this is not borne by the supermarket but by the taxpayer. This means that we are subsidising the supermarkets' price war.
A simple way of avoiding this undesirable subsidy would be for local authorities to be allowed to impose a refuse disposal charge on supermarkets proportional to the number of non-returnable bottles that they sell.
