Can bacteria solve the plastic waste crisis?

The world’s prolific use of single-use plastic products, such as water bottles and plastic bags, produces about 300 million tons of plastic waste annually. While recycling programs exist, only 7-9% of plastic waste gets recycled, 12% is burned and the rest accumulates in landfills and pollutes the environment, according to the United Nations Environment Programme

Tae Seok Moon, an environmental engineer at the McKelvey School of Engineering at Washington University in St. Louis, plans to address the plastic waste problem with a bacterium that would upcycle the plastic into a value-added chemical. His work got a boost from a three-year $861,571 grant from the U.S. Department of Energy.

The grant was among 34 projects funded by the department’s Office of Biological and Environmental Research — to the tune of $45.5 million — to advance biotechnology research to create clean biofuels and bioproducts. Read more on the engineering website.
