On an expedition to the Ecuadorian rainforest, Yale students discovered a new type of fungus which may speed up the decomposition process of discarded plastics in landfills. Currently, Americans discard about 33.6 million tons of plastic each year. Only 6.5 percent of it is recycled and 7.7 percent is combusted in waste-to-energy facilities, which create electricity or heat from garbage. In result, there is a massive amount of non-biodegradable materials being tossed into landfills with a wait of about 1,000 years or so before they decompose. What’s worse, many of these materials may leak pollutants into the soil and water. The fungus is the first one that is known to survive on polyurethane alone, and it can do so in an anaerobic (oxygen-free) environment, suggesting it could be used at the bottom of landfills.
