England's single-use plastic ban changed what "disposable" means
Since October 2023, England has banned businesses from supplying single-use plastic plates, bowls, trays, and cutlery for food eaten on the premises, and many retailers have stopped stocking them for home use too. When shopping for a party, look for the paper, bamboo, or compostable equivalents now sold as standard replacements, since a straightforward plastic pack is no longer guaranteed to be on the shelf.
