In this Special Edition of Materials Village, the theme of ecological transition finds its fulcrum in the "WastEnders" exhibition, curated by the team of Materially researchers, dedicated to startups and young companies that use materials from agricultural or industrial waste in innovative applications and objects of 'daily use. The exhibition explores new families of materials that would cut waste - either because they are developed from discarded raw matter, or because they are entirely biobased and biodegradable, or because the process is totally clean. WastEnders are those projects that start from the most varied waste raw materials and that involve not only the development of new processing technologies, but also the setting up of supply chains and partnerships between the different players. The result is the activation of synergies of industrial symbiosis that help reduce waste and turn it into value in a circular economy perspective.
