What you need to know about Zeology

Zeology is easy to implement in the existing production process of your tannery. It does not require additional processes and uses similar shift programs. But, its mode of action is different to the tanning agents that we all have worked with for so many years. For example:

  • Vegetable and mineral tans dissolve in water, zeolite does not. And it should not.
  • Zeology needs a steady hand and only one acid: formic acid. No single acids and no blended acids.
  • Zeology has no basicity. The tanning properties of Zeology are not influenced by increasing or decreasing degrees of the tanning agent’s basicity.

The importance of Chrome Free tanning

The leather industry, brands and consumers ask for more sustainable materials. Chrome free tanning is the sustainable choice for tanning and the better choice, when it comes to the environment.

Not only is Zeology chrome free, it is also heavy metal free and aldehyde free. The use of Zeology instead of the traditional tanning agent has a significant positive impact on waste streams and on the biodegradability of leather. The best part: it does not compromise on leather performance and quality. Premium tanneries around the world have adopted Zeology in their tanning processes.
