Setting up a circular economy social business shared between two associations in Alta de Lisboa: Associação Espaço Mundo and Associação de moradores do PER 11. The goal is the creation of a space in the associations' headquarters that concomitantly includes a workshop with bicycle rental and a plastic recycling workshop. Each headquarters will keep one of the spaces, although the delivery of plastic can be made in the two associations that will have a shredding machine that transforms the plastic into flakes and a storage place. This plastic, by the intervention of the various machines that will be acquired (precious plastic project) and/or built by the members of the associations themselves, will be recycled, transformed and new objects and raw materials will be created. One of the ways of renting the bicycles is through the delivery of plastic. This is the link between the two workshops to be created and developed.
