Successful implementation of OnEfficiency.Strength at DS Smith Witzenhausen for quality stabilization
-
Digital solution enables data-driven production control according to flexible target values and cost efficiency
-
DS Smith records significant improvements in paper strength consistency and process stabilization
-
The solution will be available as part of Voith's MillOne ecosystem, which connects all data in one production center

With the closed-loop control OnEfficiency.Strength, DS Smith has achieved an impressive stabilization of quality on the PM 1 at Witzenhausen.
HEIDENHEIM/WITZENHAUSEN. With over 20 installations around the globe, OnEfficiency.Strength is setting new standards in data-driven papermaking. A recent installation at DS Smith Witzenhausen shows how the use of OnEfficiency.Strength can achieve impressive results in quality stabilization.
The digital solution's key impacts include savings in raw materials such as fibers and starch, as well as reductions in paper machine energy use. Using real-time data from virtual sensors to predict strength, the system controls actuators such as the jet/wire ratio, refiner, starch application and different fiber types according to the highest cost efficiency to produce the relevant paper grade in the desired specification.
As part of an optimization project at the Witzenhausen site, where 430,000 tons of corrugated base paper with a basis weight between 115 and 210 gsm are produced annually, the module initially achieved savings in raw materials on the PM 1.
Thanks to the innovative OnEfficiency.Strength module, real-time control of paper quality is now possible. Using flexibly adjustable parameters, system goals such as raw material savings, strength reduction, quality stabilization or a balanced compromise between these goals can be freely weighted.
OnEfficiency.Strength is available as a standalone solution and will be part of Voith's smart MillOne ecosystem. MillOne aggregates and analyzes all data in one central production center, providing an unprecedented level of integration and consistency in data usage to enhance human expertise and streamline production processes. Thanks to real-time data analytics, predictive maintenance and smarter decision-making, it can make mills more productive, reduce costs and increase profitability.
