Chrome-based product in a hydrolized proteic compound and process for the making thereof, comprising a step of solubilizing the protein-Chrome complex contained in tanning residues like e.g. the shavings and the trimmings, produced from tannage hide shaving and trimming steps, the fleshing, the limed pieces and the splittings, produced from pretanning processes, and the shaving sludges, allowing to effectively carry Chrome in the tanning processes and to recycle the Chrome contained in the wastes from tanning processes, directly making a product reusable in the latter.
