Cleaning up after pre-drinks, Aédén Rooney puts his empty BuzzBallz in the recycling. "It's plastic and metal, so I'd just assume it's recyclable," he said. The company behind the bright, pre-mixed cocktails that have taken Gen Z by storm said they were recyclable on its website, but experts say this is not true. BuzzBallz cannot be recycled as the PET plastic ball cannot be separated from the aluminium lid, global environmental action body WRAP said. BuzzBallz blamed a website error for claiming they were recyclable via Terracycle, a US-only scheme, but did not comment on its now-deleted FAQ that said they were recyclable where UK councils allow.
