A method for treating an animal substrate comprising:
- agitating a moistened animal substrate with an aqueous treatment formulation and a solid particulate material in a sealed apparatus, wherein the treatment formulation comprises at least one treatment agent selected from the group consisting of tanning agents, re-tanning agents and tannery process agents, wherein the solid particulate material has an average particle diameter of from 1 mm to 500 mm and/or a length of from 1 mm to 500 mm, and wherein the animal substrate is hide, skin, or leather, and wherein the particles are re-used at least once in a subsequent method for treating an animal substrate comprising agitating the moistened animal substrate with said treatment formulation and said solid particulate material in a sealed apparatus.
