21 Days was a recycling social campaign aimed at educating and promoting action within a university student community. Through our research, we discovered that low recycling rates within the student body seemed to be less a result of being against the idea and more often a result of not understanding how the local program worked. Being temporary residents, the students were also less invested in the environmental health of the community. The 21 Days campaign highlighted common recyclables such as paper and plastic, along with commonly forgotten materials, like clothing and furniture which often end up in landfills at the end of the school year. Four 3D posters were created using framed recyclables and laser-cut translucent overlays to feature examples of products that can be made from recycled materials. Additionally, a detailed city map with recycling sites was created to help students find their closest location.
