Wet White Tanning
Our tanneries use a process called ‘wet white tanning’ for all their eco-leathers. This method of tanning is a safer, more environmentally friendly which is free of harmful chemicals, like chromium, heavy metals, formaldehyde, short-chain chlorinated paraffin, volatile organic compounds or alkyl phenol ethoxylates. To verify this, the leather is tested by SGS, an independent inspection agency.
The tanning process of eco-leathers is comprised of a combination of synthetic tanning agents and natural vegetable extracts. It’s so clean that leftover leather can be recycled and used as fertilizer, unlike chromium-tanned leather. The name of this tanning process derives from the fact that, after the process, hides look white instead of blue like the chrome-hides do.
As the eco-friendly leathers aren’t treated with heavy chemicals, they can only be preserved for 6 weeks, so it can’t be held in stock for as long as other leathers. This is one of the reasons why the production is more difficult to manage and also why the production-time of our bags is so long, the process of just tanning the leather can take up to 8 weeks!
