Zeology

Zeology, the new standard in leather tanning

Towards a sustainable leather value chain

Meet Zeology: the new standard in leather tanning. It is chrome-free, heavy metal-free, aldehyde-free and easy to implement. Yet, it offers unrivalled leather performance. 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.

Zeology by Nera

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.

What are the main benefits of Zeology?

Zeology was developed as a sustainable alternative to existing tanning agents. It is chrome-free, heavy metal-free and aldehyde-free. Therefore, the main benefit is for the environment: less pollution, less discharge of chemicals in waste and waste water, no use of chromium or glutardialdehyde (GDA) and improved biodegradability of tanned material.

Specific benefits for tanneries include:

  • Consistent and predictable results (within and across batches)
  • Only minor changes in the tanning process are required (easy to implement)
  • Zeology allows lime split and full substance tanning
  • Enables production of chrome-free white splits
  • Zeo White shavings have good biodegradability
  • Grain tightness, and hence small bellies

Specific benefits for OEMs/brands include:

  • Sustainability benefits: less polution and no risk of chrome VI formation
  • Image/sales benefits: meeting customer demand for responsibly sourced materials for their intermediates/end products
  • Design benefits: the opportunity to use whiter, brighter, lightfast and heat-resistant leather
