Abstract: The present invention provides a system for tanning leather comprising from at least two tanning compositions to be used in sequence. First composition consists of zeolite having a Si to Al ratio from 0.7 to 2.5, treated with concentrated aliphatic monocarboxylic acid, the concentration of said monocarboxylic acid being more than 84% by weight, resulting in a zeolite structure which remains intact after said treatment; acidic metal salt; and a complexing agent. This first composition is in a form of a powdery solid having moisture content less than 25 %. The second composition consists of the mere zeolite treated with concentrated aliphatic monocarboxylic acid. Moreover, a method for tanning leather using said system is provided subjecting the hide to be treated to a beam house treatment followed by a modified pickling stage using a solution having a baume value less than 5 and pH from 3 to 6.
