reduce the mountain of diaper waste.
Diapers normally take 400+ years to fully decompose. Our friendly Mycelium speed up that process, helping to regenerate Mother Earth exponentially faster.
HIRO Diapers are the world’s first truly naturally degradable, high-performing diapers — soft on skin, tough on leaks, and powered by plastic-eating Mycelium to return to the Earth.
HOW TO HIRO
HOW TO HIRO
We designed the HIRO Diaper to be the least processed for the baby and also for the Mycelium to recognize it as food. Unbleached cotton, way less plastic (only where performance counts), NO toxic blue line (aka wetness indicator).
There are NO Mycelium in the diaper. Instead every HIRO Diaper comes with a sidekick: the HIRO Pouch, a cozy home for our friendly Mycelium. Just toss the pouch into the soiled diaper during changing time.
No special throw-away steps, simply toss into the garbage and wait for our friendly Mycelium to wake up, and in a couple of weeks start working their magic. Saving the planet has never been easier.
When it ends up in a landfill, nature takes it from there, with our vision for the diaper to fully breakdown.
Sustainable. Low-effort. Very magical.

REDUCE. REGENERATE.
After 4+ years of research and design, we have achieved a breakthrough in fungal digestion of plastics.
Under the best conditions, the breakdown of the HIRO Diaper starts after 2 weeks of the diaper being in the landfill. Our lab testing shows colonization of various diaper materials and other common non-wovens. It compares Mycelium and non-Mycelium products in the lab, where you can clearly see fungal colonization and digestion (evidenced by the residue of digestive enzymes and the white fungal biomass against the test jar). The figure also shows the shelf-stable fungal technology emerging from stasis after 12 days. We are working on solving this for all the different conditions around the world.
Join us on this journey to help solve the global plastic crisis, together.
