The model will advance the current state of the art by: 

  • Providing EF on a European scale, considering regional differences in lifecycle processes (e.g. waste management) to predict spatially distributed emissions factors for Europe. 
  • Providing size distributed EF over relevant time horizons, based on predictions of fragmentation during the whole polymer lifecycle, building on work in ongoing Cefic-LRI project ECO59. 
  • Using an analysis of the complete life-cycle of polymers based on complete material-flow analysis of the polymers in the technosphere. 
  • Yielding probabilistic EF through the use of probabilistic material flow analysis (PMFA) pioneered by project partners. 

The end product will be a framework for generating EF, applied to a broad range of polymer types. The EF generated will be ready for use in environmental exposure models and will be compatible with the unit-world exposure model being developed in Cefic-LRI project ECO56, and the long-range transport model in ECO57.
