The aim of the present work is to generate at laboratory scale a biomaterial developed by in-vitro technology with similar characteristics to genuine leather. The generation of an in-vitro tissue from bovine fibroblasts is carried out using a scaffold to generate a three-dimensional extra-cellular matrix (3D ECM). The development of a biopelt is by an in-vitro production at lab scale in a bioreactor with specific culturing conditions.1 New methodologies to stabilize the biomaterial generated were investigated. In particular, the biomaterial was stabilized by immersion in solutions of vegetable tannins and cross-linking agents in an aqueous-solvent medium.

This paper aims to evaluate the physical, chemical and biological processes associated with the deterioration of leather tanned with inorganic salts. The samples of leather were exposed during eight months to outdoor weathering, and then their properties were evaluated. The results indicate that biodegration starts with dehydration, a partial scission of the protein chain of the collagen, detanning and a loss of oils due to volatilization and/or decomposition.

The aim of the present work is to generate by in vitro technology at laboratory scale a biomaterial with similar characteristics to genuine leather. The generation of an in vitro tissue from bovine fibroblasts is carried out on the basis of a scaffold to generate a three-dimensional extra-cellular matrix (3D ECM). Finally, the scaffolds have to be suitable for biomaterial production at lab scale using a bioreactor with specific culturing conditions. In a further step, new methodologies to stabilize the new biomaterial were investigated. The biomaterial generation involves the elimination of the heavy water consumption steps in conventional leather manufacture. Since this biopelt doesn't need to be subjected to the beamhouse steps previous to stabilization, a reduction of 50-60% in water consumption is achieved. Consequently, pollution in wastewaters is minimized. In view of the nature of this work and the necessary explanatory work, some of the detail has been placed in appendices at the end of the paper.
