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 thatbiodegration 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.
