Adjust the good balance between packaging efficiency and food waste minimisation

A too high correction of underpackaging situation can lead to overpackaging. A too high correction of overpackaging situation can lead to underpackaging.

Use a complete LCA evaluation approach to evaluate the new packaging or better use LCA model for optimization scenarios.

Build a complete LCA model including the relationships between packaging functionality / shelflife / and food waste.

Identify variables of optimization (e.g. packaging thickness).

Use the model to determine the optimum situation.

Consider different scenarios of optimization , i.e. different variables for packaging optimization (low to high efficiency, over to under packaging) ; thickness is only an example for simple illustration.
