Be aware that reusable packaging is a special case when calculating material intensity. It is important to divide the amount of material with the average trip rate for the packaging in order to find the use of material. For instance Euro-pallet: Average trip rate is 20. The weight of a pallet is 25 kg (varies between 20-25 kg). The material used for each packaging system is:
The formulas I) to IV) are illustrated in the example in Figure 4.

The key figures can be presented in a sector diagram to make information more easily understood, see Figure 5.
