Calculation for one tonne of corrugated product

The inputs and outputs per tonne of the average converted corrugated product are reported in Chapter 4. The data include the production of the paper that is needed to produce the corrugated product.

The closed-loop system assumes the ideal case that no recovered fibres are lost from the production shavings and the collected corrugated board after use, and that the fibre quality remains constant due to the reprocessing of the fibres. The primary fibre is thus recycled several times within the system.

The calculation for chapter 4 illustrates the use of the database and the simplified closed-loop approach (no imports/exports, no growth of the loop).
