All information relates to raw material production and does not represent a complete product life cycle assessment.
* Applies to thermoset acoustic absorbers in the colours architect white, white grey and night black. For sound absorbers in titanium grey, the switch to the new raw material is expected to take place in the course of 2026.
(1) The CO₂ savings figures are based on a comparison with the standard material types we used in the past for our thermoset acoustic absorbers.
The carbon footprint (product carbon footprint, PCF) of conventional products is calculated in accordance with the requirements and guidelines of ISO 14067:2018. A methodological review by TÜV Rheinland confirmed that the PCF calculation method developed and used by the raw material manufacturer is based on scientific principles, meets the requirements of ISO 14067:2018 and the PCF guideline of Together for Sustainability, and corresponds to the current state of the art (certified by TÜV Rheinland/Certipedia). Furthermore, it was confirmed that the PCF calculation method within the framework of the biomass balance approach and the associated PCF reduction for BMB-certified products comply with the conventional LCA methodology according to ISO 14067 and the guidelines of Together for Sustainability (TfS).
(2) The organic raw materials used at the beginning of the production value chain are allocated using the mass balance approach.
RedCert2 and ISCC PLUS are certification systems for the use of sustainably produced biomass as a raw material in the chemical industry. The certifications confirm that the biomass used has been obtained sustainably, used in the required quantity in production and correctly allocated to the respective distribution products. The certificates are awarded on the basis of independent on-site audits.
