Contemporary cities are constantly evolving and digital processes seem to have entered overwhelmingly into every activity daily life as well as into everyone's home. But how much and in which way this transition will affect positively our social and working life is still to be demonstrated. In food supply chains, whether in production, processing or disposal applications, the innovation factor related to digital processes still represents an early-stage field of investigation. Advanced research on Bio-materials derived from food-waste are a strong bet for urban environments, where product replacement can significantly reduce CO2 emissions and foster the implementation of a new raw material policy to rebalance the support bio-based strategies versus industrial material use. This paper explores some urban challenges and examples related to ICT implementation and creative methods connected to 3D printing and digital fabrication connected to food waste valorisation able to influence we live our domestic spaces.
