According to the survey results, 84% of tanners surveyed said that they are or will be actively looking to source leather chemicals with a complete or partially higher biobased content than existing chemicals which have a fossil-carbon content. This confirms recent trends and launches by a number of leather chemical companies in this area and will help tanners reduce their overall carbon footprints without losing the performance characteristics of the finished leather. Leather itself, is in a great position compared with synthetics or plastic based or blended (so-called vegan) materials as the substrate (hide/skin) starts as a 100% biobased carbon material.
Although metal-free and in particular chrome-free tannages, are tough to replace a mix of new proposed EU legislation around chrome VI limits coupled with a desire for alternative tanning systems is clearly on the minds of tanners. In the ILM survey, 69% of respondents said that they were planning to move towards metal-free tanning systems for part or all of their production in the next year.
Making leather which fits with a fully circular environmental system is also generating some interest among tanners. Although one of the key features of well-made leather is its longevity in use, there is also shift towards providing brands and retailers with leather which is fully biodegradable at end-of-life. From the results of ILM 2022 tanners survey, 57% said that they were considering providing leathers which were biodegradable. However, it should be noted that 43% have no intention of going down this route currently.
