One circular material approach I keep coming back to is mycelium-based materials.
Companies like Ecovative, MycoWorks, and Mogu are using fungal mycelium to grow materials from agricultural waste like corn husks or sawdust.
What makes this interesting is not just the material itself, but the process behind it.
Instead of extracting and processing raw resources, these systems work by growing materials through biological processes, using low-value waste as the input.
The outputs are already being used in:
• Packaging
• Insulation
• Leather alternatives
• Acoustic panels
• Interior and construction elements
From a circularity perspective, this checks a lot of boxes:
– Uses existing waste streams
– Requires relatively low energy compared to traditional materials
– Produces materials that can often return safely to the environment
But despite the excitement, scaling still seems to be the main challenge.
Growing materials biologically introduces variables, time, environmental control, consistency, that are very different from traditional manufacturing.
Curious to hear from others here:
Do you see mycelium materials becoming mainstream in the next few years, or are there still major barriers to overcome before that happens?
