Combating the problem of campsite waste at music festivals, 'Cohabitent' educates and rewards patrons for being environmentally conscious. Users complete small environmental tasks and are rewarded for their efforts with points they can redeem for goods and services at the event. This project aims to make camping at your favourite music festival a more rewarding experience for both attendees and the environment. The system incorporates a smartphone app featuring 'wayfinding' and educational tools, as well as the campsite design that utilises waste generated at the event by recycling materials to create textiles for tents and filament for 3D printed parts.
