Narrative Description

What if the leather, packaging, and building materials of the future weren't manufactured but grown? Primos Tešec, a microbiologist who has worked with fungi for years, has spent the last several years exploring exactly that — using mycelium, the root-like network that forms the body of a fungus, as a binder to turn waste biomass into solid, usable materials.
The process starts with whatever a community already has too much of: sawdust, straw, or — in one striking case — the biomass of invasive plants cleared from an abandoned plot in the middle of Ljubljana. That waste becomes food and scaffolding for the mycelium, which grows through it for about five to six days, binding the particles into a solid block. The result can become packaging, insulation, furniture, or even a leather substitute — fully biodegradable, vegan, and grown from materials that would otherwise be discarded.
One of the most striking lessons from this work is fragility, not of the material, but of the field around it: broad patents filed by commercial interests discourage open experimentation worldwide. Primos's response has been the opposite of secrecy — running workshops, sharing process, and treating an "abandoned wasteland" as a site of biodiversity and material abundance rather than something worthless.
