The printing center get the paper from the swiss company Perlen Papier AG. Every day 3 trains with 4 cabins arrive by the company Tamedia, in general that are 50 pieces of paper rolls with a length of 33km. They use this paper directly to print the newspaper. In one second 9m of paper were printed by the machines. In fact, they produce 90’000 copies per day without interrupting. They use only 4 colours to create al paints.
Finally, when the newspaper is ready to distribute they bring it to 460 boxes in canton Zürich. The Newspaper 20 minute have to be already early in the morning in these boxes. It is important that every commuter can take one to read on his way to work.
The next step is not controlled by Tamedia. The SBB set up various containers to collect the old newspapers. Per week they gain about 20 tonnes of paper in Zürich. SBB Employers take the waste from the various containers out and give it Perlen Papier AG.
Perlen Paper AG recycling newspaper and send the new paper to the printing center Tamedia.
