Zeology, the sustainable tanning concept

What is Zeology?

Zeology is a truly sustainable alternative to existing tanning agents. It is zeolite-based and therefore chrome-free, heavy metal-free and aldehyde-free.

What makes Zeology unique, compared to both traditional tanning agents and other existing sustainable alternatives, is that it delivers both sustainability benefits and superior leather performance. Zeo White, the Zeology-tanned leather intermediate, is unsurpassed in characteristics such as grain tightness, physical leather properties, lightfastness and heat-resistance. In addition, its bright white color, enables white leather, and lighter and brighter colors than were ever possible before.

Zeo White

Zeo White is the Zeology-tanned leather intermediate. When you convert a pelt into Zeo White, using Zeology, it is unsurpassed in characteristics such as grain tightness, physical leather properties, lightfastness and heat-resistance. In addition, its bright white color, enables white leather, and lighter and brighter colors than were ever possible before.

How did the innovation come about?

Nera has worked on Zeology for the past few years, based on a patented technology. During this period, Nera has extensively tested the solution from lab to commercial scale, while investigating it from a scientific, environmental, application, leather and performance perspective.

Nera has worked with over 25 external partners on this innovation, including research institutions, external labs, suppliers, brands and experts. Most importantly, we have worked in close partnership with a number of leading tannery groups on the validation and scale-up of the Zeology process and leather.

What are the benefits?

Zeology is the new standard in tanning. It is chrome-free, heavy metal-free, aldehyde-free and easy to implement. Yet, it offers unrivalled leather performance! It offers the best of both worlds: the environmental benefits of a sustainable alternative to chrome and glutardialdehyde (GDA) tanning plus a reliable, consistent, superior quality of the tanned material.

Thanks to this combination, Zeology is a sustainable tanning concept that offers significant benefits for all: for the environment, for tanneries, for OEM’s and brands and, eventually, for the consumer. It is the new standard in tanning.
