02 Nov 2018 --- Dutch design graduate Don Kwaning has created a bio-based packaging material from the pith of a cosmopolitan and typically unwanted weed called soft rush. By separating the pith from the fibers, Kwaning discovered that paper, textile, foam and construction materials can be produced for use in a range of packaging applications, including dried foods packs. Kwaning speaks to PackagingInsights about the inspiration behind this novel concept, the technical process, and the challenges of commercialization.
