Innovators make our lives easier, healthier and safer. However, innovation is also leaving behind residues – the left-behinds. The EU-funded INNORES project will study these disruptive side effects. It will focus on three kinds: nuclear waste, microplastics and data waste. Specifically, INNORES will take a novel, empirically and theoretically rich approach. Instead of focusing on innovation, it will take residues as the lens to study democratic innovation societies. The project will explore how societies conceptualise, make sense of, live with, and care for innovation residues, and how this shapes their relations to innovation. By using a specifically tailored qualitative, comparative mixed-method approach, INNORES will investigate these leftovers in different arenas spanning three European countries and the EU.
