Diapers made from a blend of seaweed and eucalyptus called SeaCell.

The market with diapers awaits the arrival of new material. Swiss researchers have developed new reusable diapers, which do not contain cotton but are made from a mixture of seaweed and eucalyptus called SeaCell.

The invention of the disposable diaper was a godsend to new parents. It’s hard enough dealing with the grueling schedule of round-the-clock diaper changes, let alone pinning and hand-washing cloth diapers. Brands like Pampers and Huggies really did parents a solid by inventing diapers that could be conveniently thrown out.

But of course, there’s a flip side: Disposable diapers also come with a massive environmental footprint. On average, 20 billion disposable diapers are thrown out in the United States every year, according to the Environmental Protection Agency. That’s the equivalent of 3.5 million tons of waste. And modern diapers aren’t just made of paper and cotton, but also plastic polymers that soak up and trap fluid, plastic outer shells that keep the diapers waterproof, and chemicals like bleach and perfumes that mask the smelliness.

It’s unclear how all of these materials and chemicals impact a baby’s health—but it’s quite clear how they hurt the environment.

 Diapers don’t biodegrade, but sit in landfills for hundreds of years, slowly releasing toxic chemicals and greenhouse gases.

For years, environmentally conscious parents have relied on cloth diapers, generally made from cotton, a crop that requires a lot of water and has a large carbon footprint. A new blend of seaweed and eucalyptus material revolutionizes the diapers production, since it is more sustainable than cotton cloth diapers.

And SeaCell also happens to be naturally antibacterial and full of antioxidants, so it is actually good for baby’s skin. It’s called the Sumo because, well, your baby will look like a little sumo wrestler in it. Sumo is made up of three parts, all made from SeaCell. There’s a soft inner layer that makes contact with the baby’s skin, an absorbent inner core, and a waterproof outer layer to prevent any leaks. This outer layer is made in partnership with a Swiss company called Schoeller, which makes a biodegradable, recyclable, waterproof fabric called EcoRepel that does not erode with repeated washing.
