Characterization Factors for Microplastic Emissions in Life Cycle Assessment Considering Multimedia Fate Modelling

These data provide supporting information for a forthcoming publication proposing new Regionalized Characterization Factors for Microplastic Emissions in Life Cycle Assessment. 

The Characterization Factors (CFs) are developed thanks to a fate model based on SimpleBox4Plastics: https://doi.org/10.5281/zenodo.5743268 and adapted to meet the USEtox methodology. 

They are derived from the "Regionalized_CFs_for_MP_emissions_in_LCIA.ipynb" script available on GitHub at https://github.com/Julouve/Regionalized_Characterization_Factors_for_Microplastic_Emissions_in_LCIA.git

The CFs are developed for 14 polymers (EPS, PP, LDPE, HDPE, PS, PAN, PHA, PA, PLA, strach blend, PBAT, PET, PVC, TRWP) at 5 sizes (1, 10, 100, 1000, 5000 μm) for 9 different regions (North America, Latin America, Europe, Africa & Middle East, Central Asia, Southeast Asia, Northern regions, Oceania, World) for 9 environmental compartments (air, lake water, river water, sea water, their sediment, natural soil, agricultural soil) on two scales (continental & global) and for 3 ecosystems (marine, freshwater and terrestrial). 

CFs are computed thanks to 2 approaches: a surface approach (in PDF*m2*year/kg) and a species approach (in PDF*year/kg or species*year/kg).
