Abstract (en)
[origin: WO2018025210A1] Use of olive mill waste waters (OMW) in at least one step of the leather tanning process in the tanning industry is described. Preferably, said olive mill waste waters are used as bactericides, tanning agents, or tanning adjuvant agent and/or antioxidant agents to prevent the formation of chromium (VI) during the retanning step. Advantageously, a tanning composition comprising said olive mill waste waters (OMW) and suitable additives is described.
