Resources from agricultural crops and industrial livestock are renewable.
Livestock farming is functional to the production of leather, as it is made from leather discarded from slaughter plants as a by-product.
The tanning of hides is one of the oldest forms of recycling, using as raw material a material unusable for food purposes (waste), and then intended for disposal, transforming it into a product with high added value.
Raw hides and skins, as waste material from the animal husbandry industry, are included in the leather production cycle. This application makes it possible to reduce global pollution by avoiding the incineration of hides and. The possible destruction of animal hides would contribute to the production of greenhouse gases. Thus, the tanning production process is a sustainable industrial activity.
