The research included
the study of Ingrao et al. (2015a) concerning application of Life Cycle Assessment
(LCA) to EPS trays of equal dimensions and production technology
compared to those made of EPLA that are the object of the
present study. Here, the two types of tray (PS vs. PLA) were compared
based upon the related GWP100 values, so highlighting those causing
the lowest GHG-emissions.
