The High-G-Technology for efficient fiber loss reduction
Pfleiderer Teisnach GmbH & Co. KG is a highly specialized traditional paper manufacturing company founded in 1881, which produces up to 40,000 tons of specialty papers from a spectrum of over 100 grades on 3 paper machines. Based on virgin fibers and recovered paper, the team of 200 well-trained employees produces FSC-certified grades for the sectors of food packaging, industrial use and decoration & packaging. In order to meet ongoing market transformations and customer requirements, a strong focus is placed on optimizing existing products and developing new specialty paper grades. In this way, the company can distinguish itself as one of the first to transform raw materials such as grass and silphia into commercial products. In 2022, construction of a high-tech biomass power plant began to maintain competitiveness and ensure greater independence from the global energy market.
The award-winning Munich-based GreenTech start-up ECOFARIO has developed and patented an innovative, highly efficient, 100% scalable and at the same time cost-effective process based on the hydrocyclone principle. The so-called High-G technology was originally created by ECOFARIO to efficiently eliminate microplastics and the associated pollutants as a final cleaning stage in municipal or industrial wastewater treatment plants.
In addition to this application, a large number of trials in the field of paper production have shown great potential in the separation of light and heavy contaminants as well as in the recovery of fibers from reject streams. For this reason, an ECOFARIO unit was installed at Pfleiderer in Teisnach on PM2 in July 2022 to reduce fiber losses in the approach flow system. Here, by means of an additional tail stage to a modern cleaner system, on average more than 60% of the previous fiber losses are reduced without sacrificing efficiency on the paper machine or product quality. This results in a very attractive return on investment while optimizing the ecological footprint of the production process.
