Trousers based on recycled tyres: The newest product line of the outdoor apparel company VAUDE, which will be available in stores from March 2022, not only stands out due to its timeless design, robust material and simple reparability — the trousers are also sustainable, as chemically recycled scrap tyres are used as a raw material. With this project, BASF and VAUDE seek to contribute towards reducing waste and preserving valuable resources.
BASF and Vaude Working Together
“Our Ultramid® Ccycled™ is an innovative polyamide-6 that can be used to manufacture high-quality textiles. During production, we save fossil-based raw materials while also offering our customers a reduced carbon footprint,” stated Christoph Gahn, vice president Business Management Polyamides at BASF.
René Bethmann, Innovation Manager at VAUDE, added: “We want to be a pioneer in building up a circular economy for our functional clothing. Our goal is to make a measurable contribution for the environment. This clearly includes reducing the amount of primary fossil resources used, as well as cutting down on the CO2 emitted when making our products. By using Ultramid Ccycled, we can reduce the carbon footprint by more than half*.”
BASF feeds pyrolysis oil from old tyres into its production operation in Ludwigshafen, and in doing so partially replaces fossil resources. The share of recycled raw material is assigned to certain products manufactured in the operation using a certified mass balance approach. As products with “Ccycled” in their name have exactly the same properties as the equivalents made from fossil raw materials, customers can process them in the same manner and use them in their conventional processes. Accordingly, Ultramid Ccycled can also be used in applications with high quality and performance requirements, such as in the textile industry.
This is an example of how taking pyrolysis oil back to basics and using it to replace fossil originated materials may be a way ahead. As more options for the use of pyrolysis oil come to the fore, the greater the market acceptance for the end product of pyrolysis. This development from BASF, highlights the end use for oils from Pyrum Innovations and New Energy (Hungary).
