The present invention describes a fully bio-degradable probiotic composition and its method of use as leather tanning auxiliary to offer a green technology to reduce waste and increase the value of by-products reducing the need of synthetic chemicals and improving the quality of effluents. Probiotics or beneficial microorganisms are used to obtain biochemicals through a controlled fermentation of natural ingredients. The result of the process is a consortium of metabolites used in conjunction with probiotic bacteria wherein product has properties very similar to traditional leather auxiliaries extensively used during the leather making process, such as wetting, dispersing, degreasing and solubilizing agents. Therefore, they have clear applications not only in the beam house operations, but also in wet-end and finishing. |
