Experience with a closed recycling loop for felts

Recycling is an important aspect of Voith Paper's sustainability strategy, which aims to conserve resources and reduce the carbon footprint.

Our goal is to establish a closed material cycle for press felts, thereby keeping high-quality materials in circulation and making an important contribution to environmental protection.

As a full-line supplier, we are committed to integrating the cradle-to-cradle principle. With the “Design for Recycling” concept, we ensure that recyclable materials are used throughout the entire product development and manufacturing process. To reduce the considerable carbon footprint of new polyamide, which is derived from petroleum, Voith has started to use chemically recycled polyamide materials.

Voith works closely with Aquafil S.p.A., a pioneer in PA6 recycling, to reprocess used felts. In the process, used PA6 is efficiently cleaned in several stages using depolymerization and converted into new high-quality PA6 granulate (under the brand name ECONYL). The original properties of the material are fully retained, which means that Infinity+Green felts can be recycled repeatedly in a closed loop without any loss of quality.
