Company SODEXO has contacted me in winter 2021. They offered a colaboration on recycling process of their expired PVC cards. The aim of this project wast to reuse this material into the valuable product.
After testing of different technologies for processing this material such as shredding, melting I considered to make an original bench construction.
The idea is to drill holes into cards and mount them next to each other without additional glue application. Later I made a mechanical design proposal of whole assembly and estimated a number of cards for this product.
Although assembly took longer then I expected (18 hours), and high material cost for side supports, I do not regret this experience. A bench was placed on Technopark square in Liberec, which is a public place in city center.
Thank you for colaboration.
