1.4 How to calculate key figures in practice

In order to calculate the net material intensity, the total material intensity for the primary packaging should be multiplied by the national material recovery rate for each packaging material. Table 3 and Figure 7 shows an example of a total and net material intensity calculation (see Figure 4 for the actual calculation procedure).
