With AiroGuide Tune Green, Voith launches the first DIN CERTCO-certified bio-based guide roll cover for more sustainable paper production

With the AiroGuide Tune Green, Voith is setting a new standard in the field of papermaking products made of renewable raw materials. As the latest member of the AiroGuide guide roll cover family, AiroGuide Tune Green is certified according to the internationally recognized DIN CERTCO for bio-based products. The guide roll cover combines all the advantages of the proven AiroGuide technology while enabling the reduction of the carbon footprint. The new innovation aligns with Voith's long-time commitment and ambitious goals to accelerate sustainability for papermakers as well as in its own production.

"With AiroGuide Tune Green, we are the first in the market to provide a DIN CERTCO-certified guide roll cover made with bio-based materials. We offer our customers a sustainable alternative and thus set a new milestone on the way to a more sustainable future of paper production", says Ralf Moser, Global Product Manager at Voith.

AiroGuide Tune Green is a composite cover using bio-based raw material with mineral fiber reinforcement. It is particularly designed for the wet end and features improved corrosion protection with enhanced edge sealing to meet the corrosion requirements in humid areas. Its good stress resistance and high wear resistance result in less grinding and maintenance requirements compared to standard covers. Therefore, the roll cover leads not only to less wear of the fabrics and reduced waste but also contributes to important resource savings in paper production.

Due to the combined development of the AiroGuide Tune Green and SkyClean doctor blades, the machine can operate without additional lubrication showers – targeting less water consumption and reduced misting.

"As part of our sustainability program Papermaking for Life, we are focusing on the entire product life cycle, among other things. The importance of this is also reflected in our customers' strategic orientation and diverse activities. This certification confirms that Voith, as a full-line supplier, provides products and services that support the global commitment to sustainable and resource-saving paper production", says Thomas Jäger, Senior Vice President Sales Fabric & Roll Systems EMEA.
