As certified by internationally recognized laboratories, LG leathers meet Metal Free standards*, and hence does not contain heavy metals of concern, specifically: chrome, aluminium, Iron, titanium and zirconium nor the organic compound of concern Glutaraldehyde.
This is obtained by a specific tanning and re-tanning process and by a carefully engineered class of finishes.
* Recognized standards impose that such leathers must contain less than 1000 parts per million of the total sum of heavy metals.
LG Tanning and re-tanning process is primarily* based on natural products obtained from vegetable renewable resources like: chestnut trees, gallnuts, hemp plants and so on. Plants are harvested following FSC or PEFC standards of sustainability.
Moreover, wastes from finished or semifinished leathers are recycled as organic fertilizer in facilities close to the tannery (see picture below). Notably, unlike traditional veg. leathers, LG articles satisfy the highest standard tests required by top shoes and handbags brands.
* Over 80% of the total tanning substances.
