Is it safe to use?

Zeolite is a microporous material, based on the most abundant raw materials in the earth’s crust. It is chrome-free, heavy-metal free and aldehyde-free. It is safe to use for end-consumers as well as for professional workers during the leather production process. Zeolite is used in many other products such as toothpaste, detergents and detoxing pills.

 

What are the environmental effects?

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 wastewater, no use of chromium or glutardialdehyde (GDA) and improved biodegradability of tanned material.

How is it different from existing tanning solutions?

Compared to traditional tanning agents, Zeology is game-changing:

  • Zeology is chrome-free, heavy metal-free and aldehyde-free
  • It has positive effects on the environment, including cleaner wastewater, no chrome in the waste streams
  • It has positive effects on the leather quality, e.g. tightness, flat grain, light colors, lightfastness, heat resistance and high physical properties
  • Economics need to be discussed face to face.

 

Why is it named Zeology?

Combining a keen interest in sustainability, and a thorough study of Zeolite, led to the invention of Zeolite-based tanning. Therefore, the sustainable tanning concept is named ‘Zeology’. It is a contraction of the words ‘Zeolite’ and ‘technology’, and also refers to a ‘subject of study or interest’ (just like psychology or theology). It suggests that it is a whole different ‘field of study’ in the leather industry, in which a lot of knowledge and experience is gathered.
