Cold Pasta began as a reflection on design as a political act and its role as an agent of change in the current global context, marked by the socio-environmental crisis. It is based on a sustainable approach to design, with a focus on Do-It-Yourself materials in order to change the way things are produced and consumed. The research and material experimentation utilized food waste, specifically eggshells, combined with a food additive to create a bio-based paste for 3D printing.
