Texas startup sells fungi that eat plastic to reduce landfill waste

Could baby poop, fungi and landfill waste work together? This is the concept behind a new product from an Austin-based startup, which sells disposable diapers with fungi that are designed to break down plastic.

Hiro Technologies MycoDigestible Diapers come with a packet containing fungi that should be placed in the diaper before throwing it away. The fungi will begin biodegrading after a few weeks when they are exposed to moisture in feces and urine.

Disposable diapers are a significant contributor to landfill waste. According to the Environmental Protection Agency, approximately 4 million tons worth of diapers was disposed in the United States last year without any significant recycling or composting. It takes hundreds of years for diapers to decompose naturally. The very first disposable diaper is still sitting in a landfill.

Hiro Technologies used fungi to combat this problem. These organisms, which include molds, mildew, and yeasts, derive their nutrients from organic matter. Researchers from Yale University discovered in Ecuador in 2011 a fungus that feeds on polyurethane - a polymer commonly found in plastic products. The researchers figured that the fungus Pestalotiopsis could survive in landfills, which are environments without oxygen.

Tero Isokauppila is the co-founder of Hiro Technologies, a Finnish entrepreneur and founder of Four Sigmatic. He said that more than 100 species are now known to be able to degrade plastics.

"Many moons ago, fungi developed to break down trees. Especially this hard-to -break-down compound called lignin. "Isokauppila explained that the carbon backbone in plastics is similar to its carbon backbone.

Hiro Technologies has three sealed jars that show the decomposition stages of a diaper treated over time. Isokauppila says that after nine months the product looks like black soil, which is "just digested and basically earth".

The company said it needed to do more research in order to determine how the product would decompose under real-world conditions and in different climates. It hopes to have data available to make "consumer facing claims" by next summer. The company also plans to test plastic-eating mushrooms on adult diapers and feminine care products.

For the moment, "diaper packages" are being sold online for $35 per week. Miki Agrawal said that the MycoDigestibleDiapers have been generating excitement among consumers and investors ever since they launched about a year ago. She declined to provide details. Agrawal stated that the company chose to focus on diapers because they are the most common household plastic waste.

Agrawal stated that "there is a detrimental lasting effect which we have not really thought about or considered." "Because, when you throw away something, no one asks themselves, "Where is away?"
