McDonald's has argued against putting customers' car registrations on their takeaway bags, as had been looked at as part of a plan to tackle littering.
Swansea Council's head of waste, Chris Howell, said in a meeting this week that the Welsh Government had explored this idea with McDonald's in a bid to discourage littering. Mr Howell said his own view was that it was a good idea but that applying it could be problematic. He told the council's climate change corporate delivery committee there was an issue about which fast-food companies would "go first" with such an initiative.
He said: "If McDonald's do it, then people will just go to Burger King instead of McDonald's, because nobody wants to have their private details printed on that packaging."
