A newly-discovered type of mushroom could not only play a crucial role in slashing plastic pollution, but could have myriad other uses in addressing the environmental plastics crises the planet faces. Discovered in 2012 by Yale University students, Pestalotiopsis microspora is a rare species of mushroom from the Amazon rainforest that’s capable of subsisting on a diet of pure plastic, or more accurately, the main ingredient in plastic–polyurethane–before converting the human-made ingredient into purely organic matter. It can live off of our plastic waste, without oxygen–meaning that the rare breed of mushroom would make an ideal agent for landfill clean-up, literally from the bottom-up.
