Use of 2,4-dihalo-6-substituted-1,3,5-triazines as condensing, cross-linking, tanning, grafting, curing agents for the production of amides, esters, thioesters, and stabilized collagen and leather, CMC (carboxymethyl cellulose), synthetic and natural polymers. The process enables to obtain non-toxic and totally free of heavy metals products characterized by Tg values between 80° C. and 100° C.

Use of probiotic technology to support tanners to reduce waste and increase the value of by-products reducing the need of synthetic chemicals, improving the quality of effluents and reducing the carbon footprint to the environment. 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 including viable probiotic microorganisms with properties very similar to traditional leather auxiliaries extensively needed during leather production, eliminating or reducing the need for use of toxic chemicals and compositions.

The present invention relates to the use of reactive colourless and metal-free protein cross-linking agents for the cross-linking (tanning) of protein-containing substrates, said agents are environmentally friendly and give an improved fixation yield, a long-term cross-linking (tanning) stability and good washing off properties. The present invention further relates to processes for the cross-linking (tanning) of protein-containing substrates thereby creating an environmentally friendly process which minimizes the use of chemicals and further improves the quality and efficiency of the tanning and dyeing process.
