The invention relates to specific chrome tanning agents and also to their use for the tanning of hides and skins, and to the leather and pelts obtainable as a result. It further provides a new process wherein the protein-masked chrome tanning agents of the invention are obtained from materials containing chromium and collagen, more particularly from leather production wastes such as leather shavings, for example. This enables recycling of chromium-containing leather production wastes, thereby permitting a significant reduction in the amount of such wastes, a fact which leads to considerable economic, environmental and logistical advantages.
