Scroll down to read more

Around 70% of all the wastewater generated in traditional leather production starts in the beamhouse. Proviera® - Probiotics for Leather™ improve the wastewater of traditional beamhouse processes provably and significantly. Scaling up your current beamhouse technology with Proviera® - Probiotics for Leather™ is the clever and simple way to make your wet-end beamhouse systems more sustainable.

Probiotics, tanners’ pro environmental biochemistry

Proviera® - Probiotics for Leather™ leather biochemicals can cut water requirements, cut chemical requirements, waste and time. Derived from a controlled fermentation of probiotic cultures and natural raw ingredients, Proviera® - Probiotics for Leather™ are made in a natural process that means all products in the range are 100% biodegradable and hazard-free, with clear benefits for our industry, customers and the environment.

Natural biochemicals to improve your beamhouse performance

Proviera’s sustainable beamhouse chemicals use a powerful blend of probiotic-derived biochemicals. With this unique formulation, tanners can produce high-quality leather while reducing their former environmental impact significantly. In addition, Proviera® - Probiotics for Leather™ is flexible, which means it can be applied at a wide range of pH values and temperatures. It can also be stored for a long time.

Probiotic leather applications

Proviera® solutions - ProSoak™, ProSpread™,ProDegreaze™ and ProDegreze™ Plus - can be used on any type of hide and skins for soaking, liming, deliming, degreasing and other process steps. We can help you select the solutions that match your needs. The key advantages of Proviera® - Probiotics for Leather™ include:

Naturally: the probiotic leather advantage

Every tanner knows that processing hides generates lots of wastewater and solid residues. This means that tanners must manage excesses of non-leather materials to avoid pollution and trouble with statutory provisions. There are three ways to do this: reducing chemical use through optimal dosing and exhaustion of processing agents, reusing chemical auxiliaries wherever possible and recycling solid residues for use in other industries.

Biotechnology in the form of probiotics help tanners to implement these strategies by reducing needed chemicals, improving performance of auxiliaries and adding value to by-products. Additionally, technology based on probiotics creates other sustainable benefits. These include a natural fermentation process, renewable raw materials, 100% biodegradable and safe biochemicals and a lower carbon footprint. Probiotic leather also tends to be better quality.

Proviera® - Probiotics for Leather™ is produced by Proviera Biotech and licensed by Stahl.

Clean labeled products with NSF product registration

Hide by-products from the leather production process are typically used for other purposes. For example, the lime fleshing and lime splits of the hides often become a raw material for collagen and gelatin producers in the food industry. Collagen and gelatin are foodstuffs that end up in the food we eat can hardly be replaced. Auxiliaries used in the beamhouse for soaking and liming should therefore be as much as possible clean and therefore clean labeled, so the raw materials are safer to use for the food and beverage industry.

Stahl´s Proviera® - Probiotics for Leather™ are NSF registered and support such endeavors.

The NSF registration of the Proviera® range ProSoak™, ProSpread™ and ProDegreaze™ assist consequently food and beverage processors meet certain certifications that require them to show their products are clean labeled. It supports the efforts of the Global Food Safety Initiative (GFSI) and the Hazard Analysis and Critical Control Point (HACCP).
