In this case, it is assumed that an overpackaging situation is considered, i.e. the optimization of environmental performance targets the reduction of packaging intrinsic environmental performances.
Check the different possibilities to decrease packaging intrinsic impacts.
Reuse or recycle packaging materials.
Reduce the packaging weight or the number of components or materials.
Use monomaterials or make sure that the packaging can be disassembled.
Use alternative materials (introduction of recycled materials, use recyclable materials, use biobased materials).
