Lanxess launches retanning agents based on biopolymers

German specialty chemicals company Lanxess has developed a new class and range of genuine retanning agents. The Levotan X-Biomer technology, which effectively utilises biopolymers for a more sustainable production of high quality leather, was presented by the company at the All China Leather Exhibition 2014, which started from September 3, 2014 in Shanghai, China.

 

With the new technology based on biodegradable polymers, Lanxess' experts have accomplished an innovative leap forward in retanning chemistry. “Decades ago, the development of synthetic retanning chemistry has changed the leather industry. Now, we think the time has come for a next-generation innovation that once again opens the door to the future,” said Dietrich Tegtmeyer, Vice President of Product Development and Application at the Lanxess Leather business unit.

 

To become increasingly independent from fossil fuel based raw materials, the incremental substitution of petroleum-based chemicals is one of the key challenges for the leather industry in the years ahead. Lanxess is a driving force behind the formulation of advanced leather chemicals derived from renewable resources.

 

As an alternative to synthetic retanning agents the new patent-pending Levotan X-Biomer range includes a complete portfolio for all key steps of the retanning process. The chemistry behind it however, is completely different. All products are based on biodegradable polymers, which are produced from renewable raw materials and specifically functionalised for retanning applications in a biologically engineered process. Thus, the Levotan X-Biomer technology enables the production of wet blue leather that fulfills the high technical requirements demanded, e.g. for automotive leather or children's footwear. At the same time, tanners benefit from a significantly improved sustainability profile.
