Time has been called on the estimated 1million plastic bottles used by festival-goers at Glastonbury. For its next event, in 2019, a site-wide ban on plastic bottles is in the planning stage. Presumably this means the sale of new plastic bottles rather than a complete ban on bringing in bottles. Revellers will be encouraged to use the water kiosks and stainless steel refill cups it introduced in 2014, organiser Emily Eavis told BBC Six Music.
