17 million of them are binned every day in the European Union alone. This new diaper is more sustainable than any other reusable cloth nappies. The textile is antibacterial and antioxidant-rich, so it is beneficial for babies' skin. It's also sustainable to harvest and produce, giving it an advantage over the textiles used in most cloth nappies on the market. It is also more easily recycled, with no need to disassemble its components. Kahlfeldt engineered SeaCell into three layers for Sumo — a soft and absorbent inner layer, an even more absorbent core, and then a waterproof outer layer that prevents any liquids from leaking out. The waterproofing was enabled by a partnership with Swiss textile company Schoeller, whose EcoRepel technology waterproofs fabrics without affecting their biodegradability or recyclability. In most cloth nappies, the absorbent layers are laminated with polyester or polyurethane, so they cannot go on to be recycled.
