Designed to promote recycling, CapDJ is the world’s first smartphone app that users play with a pet bottle cap.
KAYAC was involved in planning and developing software.
By downloading the app, attaching a sticker () made of the same material as a cap, and putting the cap on the app and scratching on it, users can enjoy DJ experience. In the game, various items from recycled caps (vaccines, plastic items for office supplies and furniture) are shown in animation. It naturally encourages users to recycle while enjoying the game. The sticker is not available for the public.
This app has been developed as a part of a cap recycling trial project in a region where cap recycling is promoted.
