Historically, engineers have been at the forefront of developing technology that has made massive changes for the betterment of society. Why can't we do the same with solving the plastics problem?Lucas Ellis is an assistant professor of chemical engineering at Oregon State University. He's researching two potential solutions to help solve the plastics problem.
The first combines chemistry and biology capable of depolymerizing mixed plastic waste, like polyethylene terephthalate (PET), polyethylene (PE), and polystyrene (PS), and funneling these compounds into a single product, like a biopolymer or a precursor for nylon product, using an engineered microbe.
The second approach uses tandem synergistic chemistry — alkane dehydrogenation and olefin metathesis — to depolymerize polyolefin polymers at temperatures below 200 °C using abundant alkane co-reactants and robust heterogeneous catalysts.
