My intend is to explore and classify waste products and find ways to bring together fellows who can upcycle these materials in the context of existing or new product groups and; in the context of hobby and craft objects. Such new ways of handling waste products and abandoned materials would build new interest groups, thus, creating communities. Exploring and classifying waste and abandoned objects/materials; sharing this classifications with Artists, makers, hobbyists, craftsmen and discuss about new ways of building/manufacturing of these materials with them. Upcycling is key to take attraction of the communities. My work will be linked between economy- technology; cradle-to-cradle design; global warming... Streets, junkyards; studios/workshops of artists, craftsmen...; this field will help me to understand atelier working habits better and design/develop common spaces for the public for meeting and practicing purposes.
