Sensitivity analyses were performed for the following key parameters:
maize and potato starch (economic allocation) produced
in Germany, maize starch (mass allocation) produced in Italy, Land
Use Change (LUC), biodegradation level for the prototype in landfill
(50%), use of renewable electricity (wind) for the prototype
expansion process. Table 3 shows the “Cradle to grave” LCIA results
as a percentage difference compared to the benchmark (i.e. porthole
spacer in EPS, base scenario).
