cleantan®-Process: Resource-efficient tanning of leather without wastewater

The innovative leather tanning process developed by Fraunhofer UMSICHT, in comparison to conventional tanning, allows for a reduction of chromium-contaminated wastewater by more than 95 percent, a savings of more than half of the chromium tanning agent, and a 75 percent reduction of the tanning time. At the Oberhausen site, a tanning system on a pre-industrial scale has already been set up, in which up to 500 kilograms of hide can be tanned in a single step.

Impregnation: Plastic surfaces free of bacteria thanks to carbon dioxide

Fraunhofer UMSICHT combines the advantages of compounding and surface coating by impregnating plastics with supercritical carbon dioxide. Based on this manufacturing process, silver particles can be introduced in surfaces such as door handles close to the surface and with material efficiency stopping the multiplication of bacteria.

The right bio-based plastic for each application

Be it the entry into the manufacturing of bio-based plastics or the expansion of the product portfolio, Fraunhofer UMSICHT supports its customers from the planning of the recipe, via the process, all the way to the finished product made of bio-based plastics. The compounds and composites developed at the institute offer a specific, often even novel set of characteristics that corresponds to those of fossil-based polymer materials or exceeds them. All products can be processed on conventional machines and are cost-optimized with a concurrent eye on market opportunities as well as availability of resources.
