Towards the definition of Circular Bio-hybrid Building Materials. An experimental glossary linking research and design

In a joint effort to increase the level of circularity in the construction sector, research is advancing with a new approach that looks at hybridisation between organic and inorganic materials, combining circular design principles with bio-inspired multi-species and multi-material innovations. This perspective is a fundamental step in the process of defining Circular Bio-hybrid Building Materials, the subject of the research. The methodology combined an extensive literature review with the construction of an experimental glossary of 55 key terms, later applied to 12 emblematic case studies ranging from architectural projects to experimental prototypes. The conclusions reveal multiple trajectories of research and design, highlighting the opportunities and challenges of bio-hybrid approaches, particularly regarding End-of-Life disassemblability, and leading to an initial definition of Circular Bio-hybrid Building Systems.
