As nearly 70% of the wastewater from leather production processes comes from beamhouse systems, Stah’s Proviera – Probiotics for Leather range of products replaces traditional leather chemicals with 100% natural products.

Stahl obtained the rights to distribute Proviera – Probiotics for Leather in February 2017. According to the Netherlands based global chemical specialist, the new sustainable range of products contains a powerful consortium of biochemicals derived from probiotics. Using this unique probiotic formulation, it enables tanners to produce high-quality leather, while significantly reducing the effluent load. In addition, Proviera – Probiotics for Leather offers flexibility in application as the product can be applied at a wide pH and temperature range, and have a long shelf-life.

Among the benefits, the most important include:

Reduced chemical usage, water usage, and waste.

Improved leather quality.

100% biodegradable.


Reduced odour levels inside and outside the tannery.
