Festivals usually work with a resuable cup company, and are typically provided with enough cups to serve all drinks throughout their event, with all the dirty cups being taken at the end of the event to be washed offsite. Some very large events, or those near to facilities, may install washing stations onsite or wash daily.
Audiences either pay a deposit or a non-returnable one-off charge for their first cup, and then exchange dirty cups for clean each time they purchase another drink. For example Refresh West managed a full reusable cup system for Love Saves the Day (capacity 20,000). The audience paid a one-off £1 levy for their first cup, and then exchanged dirty cups for fresh throughout the event. Signs were placed at the bars, bar-staff were trained to explain the initiative to customers, and auditing systems were put in place. The result was that many thou- sands of single-use cups were prevented from being used and discarded, making less waste and a cleaner festival site.
