Why we use Organic Tanned Leathers?
Two Major Types of Tanning
There are various tanning methods being used today. The oldest and most intricate process is vegetable tanning.
Newer, faster tanning methods make use of minerals like chromium sulfate (i.e. chrome tanning, chromexcel), which wasn’t invented until the mid-nineteenth century.
Vegetable Tanning and coloring
Vegetable tanning is the traditional method of tanning leather, its method dating back to approximately 5000 BCE. Like the name suggests, veg-tanning is an organic method relying on natural vegetable tannins from bark or other plant tissues.
Tannins from trees such as oak, chestnut, or mimosa are popular, but hundreds of tree types and other plants are known to have been used.
Coloring
We use vegetable dyeing with the automatic tinting machine, so that the entire surface of the hide is painted in the same color.
Chrome Tanning
It’s basically the same principle: to cross-link the collagen matrix to prevent putrefaction and hence decomposition. This is done by binding chrome salts to the collagen protein, forming cross-links between the two, thus creating stable structures of chromium-protein complexes. The method utilizes large rotating drums with chromium salt solutions “washing” the leather.
Chrome tanning is significantly faster than vegetable tanning and can be done in less than a day, and it generally produces a supple leather that keeps its finish but does not keep its form throughout its “life”. Life of Chrome tanned leather is significantly less than that of the vegetable tanned leather. The method of chrome tanning is responsible for about 80% of all leather production worldwide due to its properties and product efficiency, making it a low-cost way of preparing leather. The use of heavy metal minerals, however, is often more damaging to the

Environmental Impacts of Chrome Tanning
The environmental impacts of leather manufacturing can be measured by two key parameters:
1. How the leather is manufactured: from hide to finished leather
2. What inputs are used to manufacture it: chemical selection
These two parameters roughly determine how eco-friendly the leather manufacturing process is. The biggest downside to chrome tanning is purely the chemical used in this tanning process and the second major downside is the scale at which it’s practiced. Because of the fact that Tanning process takes significant amount of water which is now mixed with Chromium when released into the environment has as destructive impact as that of a drug manufacturing company releasing all their waste into the environment. Chrome has end-of-life issues too which are greater than other tanned like tree bark used in vegetable tanning.
