Vegetable tanning 

High graded marine leathers requires a careful selection of the skins we work with our agri-food partners. ICTYOS selects the most beautiful skins, initially destined for destruction. These marine leathers do not increase fishing and help to use sartly the existing resources.

•Tanning without chromium salt

Tanning is the central step in the production of leather. This step consists of transforming raw skin into a rot-proof material, leather. It is possible thanks to tannins. The latter can be based on vegetable, organic or mineral components.

The sector has developed a so-called "mineral" tanning process where tannins are replaced by chromium (or aluminium) salts, which reduces the tanning time to only a few days. Today 85% of all tanned skins in the world are tanned with chromium.

ICTYOS refuses to use metallic molecules during the tanning process., using as much renewable ressources as possible, such as vegetable extracts.

A various range of natural extracts can ben used to transform skins into leathers :

chestnut tree

Use of renewable resources

Plant tannins are molecules found in most plants (bark, fruit, leaves, roots,...). In nature, tannins are used to protect plants against pests or fungi. Each tannin is unique and has particular chemical properties and therefore different effects on leather.

It is possible to use resources that have no impact on deforestation by focusing on leaves, roots, or even fruits.

Biodegradable effluents

Vegetable tanning is slower and more water consuming than chrome tanning. However, new technologies allows to recycle almost all the water used .


At the end of the tanning process, the baths used for tanning must be treated. In the case of a vegetable tanning the resulting sludge is full of water and tannins, substances that are perfectly biodegradable.

Vegetable tanned leather uses natural and renewable ressources . 

The valorization of fish skins

•50,000 tonnes of fish wastes are produced each year in France. The main generators are the catering and food industry. A large part is thrown directly into the garbage, while only a small part is recycled.  Cuir Marin de France is convinced of the potential of these resources and is committed to enhancing these leather skins in an eco-circularity approach. This activity makes it possible to reduce the generation of waste from these two industries accordingly.

•Substitutes for chrome leather, plastics and furs
The leathers we develop are perfect substitutes for conventional leathers or materials, sometimes polluting or unethical. Each square metre of marine leather used avoids the use of controversial materials.

Made in France production

•Traceability of the origin of the skins
We pay particular attention to the origin of the skins we process. In the interest of transparency, we select all our skin suppliers in France.
In addition, it is essential to ensure that biodiversity is not indirectly affected by selecting only fish skins reared under exemplary conditions and in relation to animal welfare.

•Quality requirements for the luxury industry
France is an European leader in leather production after Italy. For decades, the know-how of French tanneries has been tailored to meet the expectations and needs of the world's leading luxury houses. Our marine leathers have been developed at the Leather Technical Centre in Lyon.
