Stahl, an active proponent of responsible chemistry, has expanded its range of Proviera-Probiotics for leather solutions for sustainable leather processing in the beam-house. The new ProDegreaze Plus offers tanners improved degreasing performance combined with real sustainability benefits. Stahl is a leading company specialised in leather treatment.

ProDegreaze Plus complements the existing ProDegreaze probiotic solution in the Proviera-Probiotics for leather portfolio. Performance benefits of ProDegreaze Plus compared with ProDegreaze, which will continue to be available, include enhanced degreasing performance, enhanced cleaning, and enhanced levelling. ProDegreaze Plus does all this while maintaining the excellent biodegradability properties of classic ProDegreaze, Stahl said in a media statement.

ProDegreaze Plus can be used at any stage in the beam-house process: pre-soaking, main soaking, unhairing, liming, deliming, and degreasing. It can also be used with pelt, pickle, wet-blue, and wet-white systems, plus Stahl BeTan beam-house solutions, Stahl EasyWhite and EasyBlue tanning systems, Stahl Densodrin and Densotan waterproofing systems, and to create Stahlite lightweight leather. In every case, ProDegreaze Plus is highly effective at degreasing a hide. It combines the highly efficient fat distribution of the original ProDegreaze with stable emulsification action to disperse it in the float. It delivers a cleaner grain and brighter colours, while having an odourless effect on hides, skins, and tannery equipment. Hides that have been degreased with ProDegreaze Plus can be used for all types of leathers, Stahl said.

Stahl added Proviera-Probiotics for leather to the company’s leather chemicals portfolio in 2016, launching three products; ProSpread for removing organic material and enhancing dyestuff, ProSoak for hydrating hides and creating a more open structure, and ProDegreaze for removing fats and improving tear and tensile strength.

All Proviera-Probiotics for leather products use probiotic microorganisms to produce metabolites that behave as wetting, dispersing and degreasing agents in the leather process. These probiotic-derived metabolites can replace the traditional fossil fuel-based agents used in the leather process. Through this they contribute to a cleaner, safer process for workers and a lower environmental footprint, according to Stahl.

With no need to change existing tannery processes, Proviera-Probiotics for leather products can be used as replacements for surfactants and as auxiliaries with existing Stahl solutions. The range also forms part of the Stahl Neo portfolio of Zero Discharge of Hazardous Chemicals (ZDHC) MRSL solutions and complies with ZDHC MRSL 2.0. Proviera-Probiotics for Leather products are almost completely made with biomass raw materials in a low-emission fermentation process. This reduces greenhouse gas emissions and minimises their impact on global warming.
