Over 150 million tonnes of plastic currently float in the ocean, and 90% of all plastic produced is landfilled. In 2012, a fungus, Pestalotiopsis microspore, was discovered in Ecuador that is able to digest and break down polyurethane plastic. The species can survive solely by ‘eating’ plastic, effectively converting the polyurethane into organic matter—and the researchers believe it can be used both in household and landfill settings. Katharina Unger of Utrecht University has developed a product—Fungi Mutarium—so that consumers can grow these mushrooms at home; eventually, once there is no plastic left in the mushrooms, the mushrooms themselves can be eaten. This project is still in early stages and is not commercially available, but if approved could have wide-reaching impacts on plastic pollution.
