To earn Crunch credits you must have a Crunch membership card. You can collect a card from any Envirobank location where Crunch is available.
Crunch credits are awarded to Crunch members for every eligible container recycled at an Envirobank location where Crunch is available.
1 eligible container = 15 Crunch credits
If you are not a member of Crunch yet, you can sign up here. It's super quick and incredibly easy.
