RT Conference Proceedings T1 Promoting Circular Economy around Plastic Waste: A New Design of Recycled Plastic Shredder A1 Tejero Olalla, José M. A1 Ladrón-de-Guevara-Muñoz, María del Carmen A1 De-Cózar-Macías, Óscar A1 Macías García, José A1 Miravet-Garret, Laia A1 Gómez-Hermosa, Fernando K1 Maquinaria para plásticos - Diseño K1 Plásticos - Reciclado AB The development and construction of the plastic shredder presented hereis part of the MAREA Plastic project, which aims to be a meeting point between theuniversity community and society, through science and technology. The project’smain goal consists in developing a circular economy environment that reduces both,the input of raw materials and the output of waste, closing the ecological andeconomic flows of resources. Thereby, this machine becomes essential for thecontinuation and proper development of such a research and social awarenessproject.The new version of the plastic shredder entails a solid design that meets the needsand requirements of the task assigned in its working environment, focusing on itsdesign and manufacture from a sustainable point of view, reusing parts of theprototype itself, as well as other disused resources, mostly provided by theUniversity of Malaga. This concept of sustainability even extends to its operation,controlling the consumption of the engine and paying special attention to durability,reliability and, above all, the safety of both, users and the shredder itself.Among other design priorities, the possibility to visualise and perfectly understandhow and why the reused plastic passes through the shredder is one of the mostimportant due to the educational purpose of the project towards a younger audienceabout circular economy. To achieve this, the machine should not only be able toshow the process in an illustrative way, but also the interaction with the machineshould be simple and fluid, without the need for previous knowledge or experienceoperating industrial machinery.
