Geladen, which is advancing a pair of filter technologies that could transform dairy processing, launched last month.

According to a release from the Wisconsin Alumni Research Foundation, Geladen Founder Mark Etzel, a University of Wisconsin professor, created a negatively charged filter useful for concentrating proteins from milk and cheese whey at a faster rate than existing filters.

“My plan now is to sublicense this technology to a filter manufacturer who would handle manufacturing, sales, advertising and customer support,” Etzel said in a statement. “I would supply the IP, technical support, consulting services, inventor involvement, limited experimental data, product prototype and handle all dealings with WARF.”

Etzel also is working on a filter that can separate one protein from another. He is a former WARF Accelerator alumnus.
