Mycelium insulation is renewable because it grows on residual streams rather than primary resources. The quickscan by New Economy for Fairm (2020) frames this as a core advantage of the material. Growing on residual streams keeps the raw material base circular and low-impact. When scaling a biobased material, it is often unclear where the largest climate impact lies.
A baseline measurement and hotspot analysis map the impact per process step, so scaling becomes targeted and cleaner. This is relevant for biobased startups, building material producers and investors in sustainable materials. Source: Quickscan Fairm (2020).
