Chemical engineer Paul Dauenhauer of the University of Minnesota has dedicated his career to revolutionizing the materials we rely on most. He’s worked to derive crucial “chemical building blocks” from renewable resources that can be used to manufacture existing products, as well as create entirely new alternatives.
Unlike materials like fallen leaves or animal waste, which decompose easily with help from microbes, the plastics we use today can’t break down as well. And they pose another environmental threat because of the way fossil fuels, whose derivatives are used to create many consumer products, including plastics, are extracted from the earth.
