A US-based biotech firm has developed a plastic-eating fungi, offering an eco-friendly solution to tackle the global nappy waste crisisPlastic-munching fungi could prove a powerful new ally in tackling one of parenting’s muckiest problems: disposable nappies. “It’s literally in mushrooms’ DNA to break down complex carbon materials,” explains HIRO’s Finnish co-founder Tero Isokauppila. Every HIRO MycoDigestible diaper comes with a sachet of fungi, which is thrown away with the used nappy. It gets to work in the presence of moisture, secreting enzymes that sever plastic’s complex carbon bonds and, in time, transform the waste into mycelium and nutrient-rich soil.
