Driving the circular economy by making TPU raw materials more sustainable
Thermoplastic polyurethane: a growing need for more circular raw materials
Bio-based plastics in a high-performance trail shoe
Our Desmopan® EC range of TPU integrates up to 60% content sourced from biomass, measured according to the ASTM-D6866 standard. Compared to fossil-based TPUs, the overall carbon footprint can be reduced by more than 20% without compromising quality or performance. Our customer VAUDE, the German outdoor gear and footwear manufacturer, used Desmopan® EC to create a bio-based plastic foam midsole for their new Lavik Eco outdoor trail shoe; an example of the supply chain working together to creating a new, more sustainable grade of raw materials. Using bioplastics in high-performance footwear also helps VAUDE to further underline its commitment to sustainability.
Working with value chain to recycle plastic for Fairphone case
The inherent mechanical recyclability of TPU means that we are expanding our portfolio of recycled TPU grades. The phone case of the Fairphone 3 is made of Desmopan® with 100% recycled content, reducing fossil resource consumption and plastic waste. From our wide network of industrial partners, we identified multiple streams of PIR (post-industrial recycled) plastics as feedstock for a new range of Desmopan® recycled TPU grades. These feature either a 30% to 100% share of recycled material. Both types are translucent and use waste streams that offer PIR material to recycle that is clean and sorted for molding into desired colors, resulting in an appearance similar to virgin plastics.
Reuse of carbon as a raw material in TPU: partly containing CO2 cardyon®
Our novel cardyon® polyol directly incorporates as much as 20% CO2, and is manufactured on an industrial scale. Several of our partners in the textile industry have demonstrated that melt spun elastic yarns made of this cardyon®-based TPU have the potential to replace conventional elastic yarns. Compared to their benchmarks, the new yarns reuse CO2 as alternative raw material, uniting a solvent-free spinning process with a more circular economy and a reduced carbon footprint. This partly CO2-based TPU that is tailored to yarn production is already commercially available, and we are supporting textile manufacturers in scaling up the melt spinning from technical demonstration into a full-scale industrial process.
ISCC PLUS will enable portfolio of mass balance certified TPU products
TPU is in an exciting phase of the journey towards a more circular economy. We have a bright portfolio of more sustainable solutions containing CO2, partly bio-based feedstock and recycled materials. Together with our value chain partners, we are pushing boundaries to further develop solutions such as mass balanced products and innovative technologies.
- Low-carbon: Alternative raw materials reduce the carbon footprint of TPU.
- Resilient: Recycled and partly bio-based TPU is resistant to oils, grease and solvents.
- Drop-in: Mass balance feedstocks work in existing systems without new investment.
- Customizable: More sustainable feedstock grades can be created for your application.
- Marketable: Materials with CO2, and recycled, partly bio-based products show sustainability.
