Urban legends ? 'Wash Your Pop Cans'
Perhap, but the answer is this:
Carlsberg can after I sent them the my idea (perhaps just a coincidence):
Also, San Pellegrino has a cover but it is made of Aluminum, again not best solution environment wise (and cost wise I suppose).
And another variation of this idea: Spinnakers beers.
It seems the above type is spreading: Uncommon Brewers . I do not know who was the first but 'Uncommon' should be 'uncommon' and use my idea: paper not plastic, cheaper and better for the environment.
