Vegetable tanning is an artisan tradition that the Tuscan tanneries have handed down from father to son for centuries, mixing antique recipes and state-of-the-art technology.
The vegetable tanning process is based on the use of tannin, active ingredient responsible for the transformation of the animal hide into a compact and resistant material durable through the years. This natural substance can be found in many different trees and vegetables, in variable concentration according to the different species. These natural tannin extracts make the vegetable-tanned leather unique and easily distinguishable.
Vegetable-tanned leather productive cycle is strictly monitored to ensure a low impact on the environment:
- No animal is killed for its skin. On the contrary, the hides used by our tanneries are the discarded by-products of the food industry
- Being tanned with natural tannins, a vegetable-tanned leather object can be easily disposed of at the end of its life, thanks to its chemical-biological characteristics.
- Our tanneries have made huge investments in depuration systems and waste recycling that make them work in full respect of man and the environment.
- Many of the substances used during the tanning process are recovered, recycled and reused in different fields e.g. agricultural fertilizer and construction field to make bricks.
- Vegetable-tanned leather, recognizable from its trademark, does not contain any toxic substance such as azo-dyes, nickel, PCP or chrome VI
