Disposable diapers contribute significantly to landfill waste and take centuries to decompose, posing environmental hazards. Parents seek eco-friendly alternatives without compromising on convenience or effectiveness.

The MycoDigestible™ Diaper is a revolutionary solution to the environmental challenges posed by traditional disposable diapers. Made from unbleached cotton and sustainably sourced softwood fluff pulp, this premium diaper offers up to 12 hours of leak protection while being eco-conscious and sustainable. The diaper's hypoallergenic and dermatologically tested design ensures baby comfort without compromising on performance.

What sets the MycoDigestible™ Diaper apart is its innovative inclusion of a small “HIRO Pouch” containing dormant, plastic-eating fungi. This pouch, when added to a used diaper during disposal, activates the fungi upon exposure to moisture in a landfill. The fungi then secrete enzymes that break down the plastic components, significantly reducing the diaper's waste footprint.

Laboratory results have shown that the fungi in the MycoDigestible™ Diaper can colonize materials within just 21 days, with complete breakdown into a soil-like substance occurring within months under controlled conditions. By harnessing the natural decomposition capabilities of fungi, this diaper offers a no-compromise solution that supports both baby comfort and planetary health.

Key Characteristics

• Made from unbleached cotton and softwood fluff pulp sourced from sustainably managed forests

• Free from chlorine bleaching, fragrances, dyes, lotions, latex, and wetness indicators

• Hypoallergenic and dermatologist-tested, gentle on sensitive baby skin

• Provides up to 12 hours of super-absorbent leak protection, suitable for day or night use

• Comes with a small pouch containing dormant plastic-eating fungi, designed to be added to the diaper upon disposal

• Developed through over four years of research and development

Environmental Benefits

• The fungi activate in landfill conditions using moisture from the diaper, breaking down plastic components within weeks

• Visible fungal growth appears in about 12 days, with significant material degradation by around 21 days

• Converts the diaper into soil-like biomass over a few months, returning carbon to the earth instead of lingering in landfills

• Reduces the long-term environmental impact of diapers, which are among the top contributors to household plastic waste

• Offers a scalable solution for biodegrading soft plastics beyond just diapers, including wipes and packaging

HIRO Technologies, based in Austin, Texas, is a venture-backed startup focused on sustainable solutions for single-use plastic waste. It developed the world’s first MycoDigestible™ diapers—high-performance products made from unbleached cotton and softwood pulp, enhanced with plastic‑eating fungi inside a companion pouch. After disposal, these fungi activate within weeks in typical landfill conditions, accelerating degradation by breaking plastic polymers into soil and mycelium. Co‑founded by Miki Agrawal (also known for THINX and TUSHY) and Tero Isokauppila (co‑founder of Four Sigmatic), HIRO brings together diaper engineers, mycologists, and eco‑minded parents. The company's mission is to turn diaper waste into nature’s reclamation cycle, reducing landfill impact and microplastic pollution. Their patented technology and award-winning approach mark a significant step toward a circular, environmentally friendly future.
