“They [disposable vapes] pollute the environment and incorrect disposal of these can be hazardous at waste centres,” the regulations read.
Campfires and disposable BBQs have also been prohibited from the festivals, however, refillable vapes are permitted.
Explaining the ban, organisers say according to NME: “This is to support the Air Quality Action Plan and in consideration of local impacts as set out in our Green Nation Charter."
The festival adds: “Anyone seen creating or fuelling a fire, or disposable BBQ will be evicted from the festival site. We have to continue to protect our future on this planet.”

“Do not bring disposable vapes,” the festival told attendees, following Glastonbury's 'reduce, reuse, recycle' policy. “They pollute the environment and can be hazardous at waste centres.”
Every week, 1.3 million disposable vapes are thrown away in the UK – or two every second with industry experts warned of a ‘dramatic rise’ in fires at recycling plants over the past year.
Headliners at this year’s Reading and Leeds festival include Billie Eilish, The Killers and Sam Fender.
