Life cycle inventory for corrugated board 2020 

Table 4 shows the calculated inputs and outputs for the production of 1 tonne of corrugated board products in
Europe with an average corrugated base paper composition. The production of corrugated board is normally
expressed in m2. However, for LCA it is preferable to have it expressed in weight.
For the average corrugated board product, the paper input is 1.12 tonnes/tonne corrugated board, with an
output of 0.12tonnes paper for recycling.
The original five datasets for the four main paper grades and corrugated board/box production from which the
data are derived, are reported in the Annex. The data for the corrugated box is calculated by multiplying the
average paper grade composition by 1.12 and adding the corrugated board/box data reported in the Annex.
