Road to innovation

Towards a sustainable leather value chain

Smit & Zoon has the ambition to create a more sustainable leather value chain together. Smit and Codyeco, two of Smit & Zoon’s subsidiaries, were already household names in Wet-end and Finishing. As Tanning is a crucial part of the leather value chain as well, Smit & Zoon is now providing tanning solutions, under our subsidiary Nera.

Nera stands for ‘NEw eRA’, as our tanning solutions mark the beginning of a new era: an era of truly sustainable leather manufacturing, throughout the entire leather value chain.

Introducing Zeology, the new standard in tanning

The first tanning solution Nera introduces, is Zeology. We have developed it as a responsible alternative to existing tanning agents. As a sustainable, zeolite-based tanning concept, Zeology has enormous potential to be a gamechanger for the leather industry. Therefore, the introduction of Zeology is another step towards a more sustainable leather value chain. Another drop to make a difference.

Best of both worlds

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, Nera is confident that this sustainable tanning concept offers significant benefits for all: for the environment, for tanneries, for OEM’s and brands and, eventually, for the consumer. Zeology truly is the new standard in tanning.
