Papier und Kartonfabrik Varel Revamping PM 4 to Produce White Testliner

Papier und Kartonfabrik Varel, Germany, reports that it is pushing forward with the revamp of its PM 4. The machine is being reconstructed to expand the mill's product portfolio with white testliner and kraftliner substitute qualities. Some of the newly installed components of PM 4 are already in operation or startup is imminent.

With a new starch preparation plant, the mill will be able to activate starch enzymatically. This process is more eco-friendly, since the usage of chemical substances is not necessary, the company explains. Also, the cumulative energy balance is significantly better compared with the thermochemical method, it adds, noting that the new starch preparation plant was put in operation at the beginning of this year.

A new indoor crane with a lift capacity of 80 metric tons was installed several weeks ago. This crane will lift all components to their final position during the time of revamp, beginning in April. Thereafter this crane will be used for tambour lifts as well as for maintenance jobs.

A newly designed 90-m³ D-pulper is set to startup at the end of April. This unit will supply pulp to PM 4-line 1.

All revamp measures are being carried out during the mill's regular manufacturing schedule, which underscores the complexity of the project and capability of the project teams, the company points out.
