Another study will be carried out and focussed
upon application of LCA with the aim of comparing the aforementioned
tray-types in terms of global impact, thus including other
environmental aspects such as, for instance, non-renewable energy
and land use. According to the authors, doing so will enable integrated
and detailed evaluations of the environmental performances related to
the trays analysed and, as a result, enhanced knowledge in the field:
for this purpose, all the assessments to be further needed will be developed
by the authors
