A sustainable fashion 
Environmentally friendly materials

Vegetable tanning 

Ecological processes require 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 in any way increase fishing and make it possible to use existing resources intelligently.

•Tanning without chromium salt

Tanning is a 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 what are called tannins. The latter can be of vegetable, organic or mineral origin.

•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.

Depending on the result you want to obtain in terms of flexibility, resistance or even colour, it is possible to use extracts:

oak 
chestnut tree
mimosa
 quebracho   

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.

We use as much as possible local resources that do not come from tree bark, although tree bark is a waste from the wood industry. It is possible to use resources that have no impact on deforestation by focusing on leaves, roots, or even fruits.

Biodegradable production effluents

•Vegetable tanning is slower and more water consuming than chrome tanning. But compared to chrome tanning, it has a lower impact on the environment.

 

•At the end of the tanning process, the baths used for tanning must be treated and in the case of a vegetable tanning there are still sludge full of water and tannins, all natural substances that are perfectly biodegradable.

 

•In the case of chromium tanning, there are still sludges that may contain chromium salts, which are dangerous if they were to spread in the environment, so they must be chemically purified. Once dried, the remains cannot be recycled in the agricultural sector (unlike vegetable tanning residues) and must be stored in a class I landfill (for hazardous waste).


Vegetable tanned leather is environmentally friendly and hypoallergenic because it contains no allergens. 

The valorization of fish skins

•50,000 tonnes of fish waste 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 a 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.
