Just had an email from them with some more details:
Thank you for registering to become a Worthy Warrior at Glastonbury Festival 2019. Welcome on board!
All of us here at Glastonbury Festival care passionately about our environmental impact and how it can be improved, so we thank you so much for all your feedback on how we're doing so far.
As a valuable part of Glastonbury Festival’s sustainability team, we would like Worthy Warriors to help us communicate all our crucial environmental messaging to their fellow campers. So take a walk, meet your neighbours and help spread the (green!) word.
Help us communicate our core messages:
Reduce - Avoid single-use plastic and other environmentally harmful disposable items such as wet wipes and non-biodegradable glitter. So please, use a reusable water bottle and encourage others to refill for free and seriously consider re-usable alternatives in all instances.
Reuse - On Sunday evening and Monday morning encourage those around you to take their tent and all their camping equipment home with them when they leave the Festival to use again and again.
Respect - Once a day, help us to distribute recycling bags to your neighbours on the campsite, so we can encourage people to respect the land and deal with their rubbish as they go along.
This year we have expanded our Worthy Warrior Team and a Worthy Warrior Coordinator will be posted at campsite bases on Wednesday and Monday to answer any questions you may have about your role as a Worthy Warrior.
We’ll be sending more updates and important announcements over the upcoming weeks, but in the meantime please have a read through these key points below:
Here’s what to do when you arrive on site:
Pick up your WW Wristband
Everyone who's registered as a Worthy Warrior will first need to pick up a Worthy Warrior Wristband from their Worthy Warrior Coordinator at their campsite base. This identifies you as a Worthy Warrior and you will need it to pick up your extra bin bags from the Campsite Stewards.
You will also need your wristband to get your T-Shirt printed at the Free Press (see below!). Bring a spare T-Shirt
If you have a spare or old unloved T-Shirt then please bring it with you. We'll be printing special edition T-Shirts for all Worthy Warriors at the Glastonbury Free Press (The Free Press is located in Theatre and Circus), Greenpeace, or Oxfam. This is a reuse project so please make use of one you already own, or pick one up from one of the Oxfam stores on site.
Monday Morning Helpers!
Those of you that said you were available to help out on Monday morning will be sent further information separately.
Thank you for your support! We’ll be in touch again before the Festival.
