Sympatex announced at ISPO Munich Online that as early as this year, more than 25 percent of the raw materials required for its membrane will be switched to bio-based sources derived from various organic waste streams (based on mass balancing). At the same time, it aims to ensure that the membrane not only maintains its high-performance values in terms of breathability and water and windproofness, but is also fully recyclable at the end of its life cycle, according to the German company. In addition, DSM, Sympatex’s long-time raw material partner, is in the process of completing the conversion of its production facilities to renewable energy. As a first signatory to the UNFCCC Climate Charter for Action for the Textile Industry (now signed by more than 100 brands and associations), DSM is thus helping Sympatex reach an important milestone on the road to climate neutrality a few years ahead of schedule. By incorporating the membranes into their collections, Sympatex brand partners will be able to fulfill an important commitment of the Climate Charter – reducing CO2 emissions by 30 percent compared to 2015 – much faster. One of the first brands is Mammut. The plan is to complete the conversion for all Sympatex membrane deliveries by the end of 2021 at the latest.
