Dr. Corinne Scown, Lawrence Berkeley National Lab: Circular plastics and their implications for the environment
October 13 @ 4:00 pm - 5:00 pm
Mechanical recycling of polymers downgrades them such that they are unusable after a few cycles. Alternatively, chemical recycling to monomer offers a means to recover the embodied chemical feedstocks for remanufacturing. However, only a limited number of commodity polymers may be chemically recycled, and the processes remain resource intensive. We use systems analysis to quantify the costs and life-cycle carbon footprints of virgin and chemically recycled conventional polymers as well as novel polydiketoenamines (PDKs) to understand the cost, life-cycle greenhouse gas, and infrastructure implications of reducing the accumulation of plastic waste in landfills and the environment.
