Environmental news and technical  innovation in the nonwovens sector

SCOTTSDALE - Dyper has become the first diapering company in the world to successfully “char” a diaper with its Byochar technology.

Biochar is a carbon-rich product created through a heating process called pyrolysis, which allows for waste to be transformed into a reusable commodity that can improve soil, assist in air and water purification, and be an additive to paints and inks for improved pigment.

With the average child using around 3,700 disposable diapers and more than 27 billion of them ending up in U.S. landfills each year, diapers rank as the third leading contributor to the nation’s landfills by mass, taking up to 500 years to break down.

Debuting in 2023, Byochar reactors will be located in select markets. When in place, Dyper will be able to reduce landfill waste and lessen overall global greenhouse gas emissions by transforming something as environmentally hazardous as a used diaper into something that can ultimately have a carbon-neutral footprint on the planet, without the use of offsets.

Byochar is the latest environmental innovation from Dyper. A major player in the premium disposable diaper category with its diapers constructed with plant-based materials and made without harmful ingredients, Dyper’s landfill avoidance program ReDyper has already diverted more than 11.5 million pounds of waste from landfills, turning their used diapers and wipes into nutrient-rich topsoil that is used in large-scale landscaping, roadside plantation, and growing sod. As Byochar technology is deployed, the process of composting will be gradually replaced in the ReDyper program.

“While there are no silver bullets to solving the plastic diaper dilemma, we feel it is our obligation to continuously look for solutions,” said Sergio Radovcic, Founder and CEO of Dyper. “We’ve started with composting, fully aware of the inherent difficulties of doing it at scale. With this innovation, we will bring modular disposal technology to complement or replace composting closer to the consumers, reducing processing and transfer times. We’re excited to see our work turn waste into something more helpful to our planet.”

Biochar technology is not new, but until now, has not been used to combat the disposable diaper waste problem. Additional benefits of the technology include reducing the processing time from several months to minutes while also serving as a soil amendment, a concrete and asphalt filler. Carbon sequestration also holds carbon captive and inert in soil for thousands of years and prevents it from being released into the atmosphere as harmful greenhouse gasses while `an efficient Byochar reactor needs less space and electricity than a traditional composting facility.

Overall, Byochar reactors have the capacity to process 2 tons of diapers per day. That’s approximately 7,200 diapers every 10 hours, or 12 diapers a minute. Converting soiled Dyper diapers and wipes to biochar yields an 80% reduction in mass. For example, 100 pounds of dry diapers yields approximately 20 pounds of biochar.

In the future, Byochar may be compatible with other diaper brands, which would effectively end diaper waste altogether (4% of solid waste) but is not compatible with non-Dyper products today. It may eventually generate carbon credits and possibly, sell credits on the trading markets, the company said.

Dyper products are made without chlorine, latex, alcohol, lotions, TBT, and Phthalates. They're unprinted, unscented, soft to the touch, yet extremely durable and absorbent, and made with plant-based materials such as viscose from Bamboo.
