After collection, raw hides are processed for preservation and then sold to tanneries. They buy raw materials according to the type of finished product they intend to produce: in this case we are talking about Italian vegetable leather. After a first phase of preparation, which includes hair removal and purification, comes the real tanning process: in this case are used tannins extracted from trees like chestnut, mimosa or quebracho. After tanning there is the final phase of greasing, almost all the times with natural products of animal origin. A drum dyeing is optional, with water based aniline dyes.
Since the seventies restrictive legislations concerning environmental matters have appeared. Concerning vegetable leather tanning these were almost redundant because, as we have seen so far, just natural products are used. We would like to remind that the animals are killed for food purposes, so we are talking of a production process which is almost entirely lacking any environmental impact. More than anything else it is a matter of optimising the resources. Tannins are in fact extracted from the cortex of the trees that are, therefore, not abated but looked after and safeguarded like a real resource.
The first benefit is the possibility to put in contact with our own body a natural product, non contaminating or noxious. Vegetable leather then is breathable and allows the body (for example the shoes) to eliminate water vapour and prevents the appearance of fungi. Vegetable leather style and elegance are unique. Vegetable leather does not grow old, matures and transforms both in colour and in brightness. Vegetable leather is not concerned about rain because, once dried, it won't show stains or halos. It is not concerned about scratches either because it is possible to make them all disappear with a simple wool cloth and elbow grease. Italian vegetable leather is a benefit both for the environment and people.
