Tannery 4.0 will help tanners’ circular economy credentials, Lanxess says
Leather chemicals manufacturer Lanxess has begun using the name Tannery 4.0 to describe the programme it launched in 2017 to allow tanners to make (on the tannery floor) Lanxess’s X-Biomer retanning agents using trimmings and shavings and plant-based biomass.

In speaking about the idea at the 2018 Freiberg Leather Days in mid-June, Dr Dietrich Tegtmeyer, vice-president with responsibility for leather industry relations at Lanxess, said Tannery 4.0 will help leather manufacturers that take it up reinforce their circular economy credentials.

The company has been making X-Biomer agents since 2014, using shavings from tanners, shipping them to Lanxess premises and then transporting the products back to tanneries for use in retanning. Producing them on the tannery floor instead will save the cost and environmental impact of shipping and packaging.

He told the audience: “There is going to be a lot of emphasis on the the circular economy in the next 20 years and leather has a great chance to make an impact. As this idea shows, we can recycle everything, including protein by-products, in an environmentally responsible way.”

Lanxess developed Tannery 4.0 in partnership with Leverkusen-based research group Invite and tanner Heller-Leder.
