Industry 4.0 describes a paradigm shift in industry, including decentralised production concepts away from mass production centres to minimise unnecessary logistics. This, in turn, will allow energy and waste saving technologies according to the principle of the circular economy and web-controlled automation to maximise process safety and reliability. Dr Tegtmeyer will cover these themes and highlight the latest results from its ReeL project with German tannery Heller-Leder in his presentation titled; “Tannery 4.0 – an opportunity for the leather industry”.


A tannery producing its own retanning agents
A tannery would be able to automatically and largely independently produce a part of its own needs for retanning agents like those offered by Lanxess in its X-Biomer range. “This project is a very promising step towards an even more sustainable production concept”, explains Tegtmeyer. “While on the one hand, ‘on-site’ and ‘just in time’ production brings enormous savings of resources in terms of energy, logistics, and packaging, on the other hand, by-products such as shavings containing collagen can be utilised as a raw material for the production of the retanning chemicals required.”
The three-year joint project with the partners INVITE and Heller-Leder has an investment of five million euros. The modular production plant constructed by INVITE is currently being tested under realistic production conditions at the Heller-Leder tannery in Germany. 

A medium sized tannery produces between one and two metric tonnes of shavings per day. With a modular production plant leased from Lanxess, the tannery would be able to produce a comparable volume of liquid X-Biomer for retanning. The process recycles shavings completely, without any residues or emissions.

Under the title of “Resource-efficient manufacturing of leather chemicals” (ReeL), the Leather business unit at Lanxess collaborated with the research institute INVITE from Leverkusen to develop a modular pilot facility.
Lanxess received the German Innovation Prize for Climate and Environment 2017 in the category “Environmentally friendly products and services” for this innovative technology.
