A reusable system is a concept for the reuse of units

for the multiple use of units, e.g. sales packaging (returnable bottles), transport packaging (containers, reusable containers), transport aids (Europool pallet) and refill systems (refillable consumption units),
to conserve resources (e.g. raw materials, energy, etc.) and
to reduce waste.
