The Tanning

Is the most important step in production, and regardless of its quality, it is what defines the final Biodegradability of the skin.

Vegetable Tanning
Vegetable Tanning

Process performed with vegetable substances, such as the bark of some trees.

This process has been around for over 5,000 years and has been, for many centuries, the main method of tanning.

The tannin content, which exists in the bark of these trees, is the substance that linked to collagen, allows the isolation of natural fibers against fungi and bacteria that are responsible for the skin degradation.

Chromium Tanning
Chromium Tanning

This tanning uses mineral tannins (chromium salts) and since it was discovered in 1858, has become the most common way of tanning a leather, especially because it is a much faster process than vegetable tanning.

The leathers resulting from this tanning and at this stage, are usually called Wet-Blue.

Wet-White Tanning
Wet-White Tanning

It is a synthetic tanning, which uses synthetic agents produced artificially, so they have no counterpart in nature. Examples of these are formaldehyde, glutaraldehyde, phenols and acrylates. This tanning method is not employed as an isolated process, but mainly as part of a tannery process combined with chromium or vegetable.
