Recovered paper is a waste product from industrial and domestic sources. After use, the waste paper is re-used for manufacturing recycled papers and paper products. Among them cardboard and cardboard packaging production.
An important first step in the manufacture of paper and cardboard products is the initial sorting of the recovered paper collected. During this, non-paper components such as metal or plastic are removed from the recovered paper. This step takes place at the waste paper treatment plant in either a manual or an automated process.
In addition, the recovered paper must also be sorted by grade and purity, as not every grade and purity is suitable for the manufacture of certain paper or cardboard products.
There are currently 67 standard grades of paper and board on the global market. The quality of the different grades is governed by EN 643, the “European List of Standard Grades of Paper and Board for Recycling” and is rigorously regulated.
