We grow ecological materials from mushroom mycelium. Each family below starts as residue and a fungal network, then becomes something a product, a room, or a hand can use.
01 — Protect
Protective forms for products that should not travel in plastic foam. Mycelium can be grown around a shape, so the cushion follows the object instead of being cut from a petrochemical block.
Useful when a brand needs light protection, a natural surface, and an end of use that is composting rather than permanent waste.
02 — Quiet
Panels and surfaces for rooms that want warmth without another plastic sheet. The material keeps the texture of its growth: soft, matte, and visibly made from fibers.
Studios and architects use this direction for acoustic presence, exhibition walls, and interior pieces where the material should be part of the story.
03 — Form
Small-batch pieces for designers who want a material with a visible life cycle. Volumes are grown to shape, then dried so the piece is stable in use.
This is the place for limited objects, retail fixtures, and studies that test how far a grown material can go before it returns to soil.
Shared character
| Question | Grybas material | Expanded plastic foam |
|---|---|---|
| Feedstock | Agricultural residues and fungal mycelium | Fossil carbon |
| How it becomes solid | It is grown | It is expanded from polymers |
| End of use | Designed to be composted | Persists as plastic waste |
| First applications | Packaging, interiors, objects | Disposable protection and fill |
Performance depends on the application. Grybas shares samples and specifications with partners directly. We do not publish certifications we have not completed.
