Sustainable PU synthetics for the shoe industry are now possible thanks to a combination of a water-based textile coating with regenerative fibers

Covestro and the Austria-based Lenzing Group, a speaker at Plastic Free World Conference & Expo, have collaborated to develop environmentally-compatible polyurethane (PU) synthetics for the footwear sector. The expertise of both partners complements each other perfectly. Covestro brings its expertise as a raw material specialist for PU textile coatings, based on the water-based INSQIN technology, while Lenzing offers expertise in the production of fibers, a wood-based material that is both renewable and natural.

The environmental compatibility of coated textiles depends on a whole series of factors. The source of the raw materials, the use of organic solvents and the consumption of energy and water are important, for example. The global warming potential of water-based PU coatings that use the INSQIN technology is considerably lower than that of solvent-based systems. The TENCEL Lyocell fiber from Lenzing reduces the ecological footprint of synthetic leather just as much, primarily because it is manufactured using an innovative recycling process that conserves resources.

“As a result, the shoe industry now has access to PU synthetics that set new standards in terms of sustainability – made possible by the combination of unique and innovative solutions from both partners,” said Thomas Michaelis, head of textile coatings at Covestro for the Europe, Middle East, Africa and Latin America (EMEA/LA) region.

Plastic Free World Conference & Expo 2019 will take place from Thursday 27 June to Friday 28 June, at the Kap Europa, Frankfurt Messe, Frankfurt, Germany. To register for this highly focused and solutions-driven event, please click here. For sponsorship and exhibition opportunities, please email
