Innovative pulping concept from Voith ensures significant reduction of energy demand and CO2 emissions at Palm
- The specific pulping energy of the new technology is more than 30% lower than in conventional dissolution systems
- The highly innovative pulping technology is already being used profitably as a pilot project at the German paper manufacturer Palm
- The development of new innovations is part of the "Papermaking for Life" sustainability program
At the German paper manufacturer Papierfabrik Palm, Voith's highly innovative pulping technology is already in profitable operation as a pilot project. The stock preparation system is designed for a production of 500 tons per day and enables the company to save 1,000 MWh of energy per year. In addition, high accept consistencies are possible, which leads to advantages in the downstream process steps.
Voith’s intensive preparatory work with a test prototype has thus paid off. The technical solution behind the optimized recycling process links two pulping technologies. The new pulping concept involves continuous HC pulping in a trough with horizontal pulping shaft and downstream screening section. At Palm, it is installed in a separate line for pulping processing scrap and reject rolls and is already in continuous operation. The pulping of standard raw materials with increased dirt loads has already been successfully tested. Here, too, the system has been able to demonstrate its advantages.
The new concept is a good example of how Voith puts special emphasis on sustainability in all projects and pursues the highest standards. This is confirmed by Wolfgang Mannes, Voith’s Senior Expert R&D Fiber Processes, who was significantly involved in the development of the concept.
Papermaking for Life sustainability program
