Lenzing operates a quality management system based on ISO 9001:2015. It forms the basis for all work processes and reinforces efforts to achieve complete customer satisfaction.

All Lenzing fiber products undergo health and safety testing. However, the ultimate responsibility for consumer health is borne by the companies that manufacture finished products from Lenzing fibers.

The Product Safety and Regulatory Affairs team (part of Global Quality Environment Safety and Health) ensures that raw materials incorporated into final products are thoroughly checked and are appropriate for the specific application.

Product Safety and Regulatory Affairs ensures that Lenzing is up to date with changes to applicable standards and regulations. The classification (Classification, Labeling and Packaging, CLP Regulation) of titanium dioxide powder, which is used as a dulling agent in some fibers, was communicated to Lenzing’s nonwoven customers in order to discuss the potential need for product changes. Various external factors prevented the continuation of the activities reported in last year’s sustainability report to transition all the remaining fiber finish components from animal to vegetable origins.

Quality improvements

Lenzing has continued to achieve major quality improvements in the reporting year, including significant improvements to spinning faults and contaminations in Lenzing’s Lyocell and Viscose factories. COVID-19-related disruptions and pulp availability challenges continued to have an impact on the quality performance of some factories which could not maintain the 2020 quality performance. Nevertheless, a net improvement on quality performance is achieved and is reflected in the quality-related KPIs for the entire group.

In 2021, the total number of complaints for the fiber business was lower indicating the effectiveness of the quality improvements implemented in both product and service quality areas. Lenzing is confident that all of its products perform well in their respective applications.

As a follow-up to the Heartbeat for Quality initiative, a new Fiber Quality strategic initiative was launched with a broader scope, building further on the material and production quality improvements, initiating projects focusing on service quality and customer intimacy, and activities that further strengthen the quality and process-driven mindset of the organization. The approach followed is based on redesigning and introducing internal systems and processes. The first designs were completed in the reporting year, with the full strategy implementation scheduled for 2022. One example is the updated Event Action Reporting (EAR) system, which is being introduced to all production lines, enabling the real-time monitoring of loss situations and cross-communication of common root causes across the operational network to prevent incident reoccurrence. The reporting system operates as an information source and supports the definition of quality improvement opportunities. In addition to the reporting system, detailed information is generated on the incidents, automated reports, and visualizations, providing real-time monitoring of quality performance.

Third-party certifications for LENZING™ fibers

The STANDARD 100 by OEKO-TEX®, Annex 6, certification confirms that LENZING™ fibers have been tested for numerous regulated and non-regulated harmful substances and are therefore harmless to human health. By monitoring raw materials and production processes, Lenzing ensures that its fibers comply with all relevant regulations, guidelines, and standards. LENZING™ standard nonwoven fibers are certified for food-contact applications under European and U.S. regulations. Lenzing uses external third-party certifications to prove the compatibility of its products in their fields of application.
