David Shonnard, Robert Handler, and graduate student Utkarsh Chaudhari (chemical engineering) were mentioned by Waste Today Magazine in “Gauging the flows,” a story about a report they co-authored (DOI: 10.1021/acssuschemeng.2c04004) that gauges whether a circular economy is achievable for polyethylene terephthalate (PET) and polyolefin polymers in the U.S.
The report, published by ACS Publications, provides material flow and life cycle assessment data sets for these materials while also estimating total supply chain greenhouse gas (GHG) emissions and energy consumption.
The report provides material flow and life cycle assessment data sets for polyethylene terephthalate (PET) and polyolefin polymers in the U.S. while also estimating total supply chain greenhouse gas (GHG) emissions and energy consumption. Polyolefins [DT1] researched include high-density polyethylene (HDPE), polypropylene (PP), low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE).
Shonnard says phase one findings show where improvements need to be made to achieve a circular economy for plastics.
“We were able to develop a systems analysis of the entire U.S. plastics supply chain for these plastics,” he says.
