To many people, waste is something no longer wanted and useless. But in the eyes of PolyU’s students and representatives from the Japanese brand poRiff, waste is something precious and can be turned into new products with impressive values and functions. The School of Design and poRiff co-presented the ‘Collage Again Material Exhibition’ in October 2018 and fully demonstrated how to handle waste in a better way. Products from poRiff and works of students from the School of Design and Institute of Fashion and Clothing were featured to inspire ideas on re-valuing and re-purposing waste instead of discarding it. These exhibits raised public awareness on used plastic bag recycling.
