UnLimited Backpack
Kuan-hua Chou
Sustainable Products, Projects and Green Design UnLimited Backpack by Kuan-hua Chou UnLimited is a recyclable backpack designed for urban cyclists. The backpack is fully waterproof and adjustable in size. A concertina structure allows the bag to expand for unexpected items and to compress into a slim shape that improves mobility. UnLimited is made of one material, a recyclable thermoplastic elastomer with different levels of hardness, and is sealed by heat welding. Most backpacks combine several materials and are hard to recycle. The single material construction supports reuse and recycling at the end of the service life.
