Latest Patents

Uhren's latest patents include a "Method of producing a metal nutrient for an animal feed" and a "Method and apparatus for treating chrome leather waste." The first patent describes a process where chrome tanned leather scrap and shavings are heated in an aqueous solution with an alkali material. This process produces a water-soluble, low molecular weight protein hydrolysate and insoluble chromium compounds, which are then separated. The hydrolysate is oxidized to remove any objectionable trace organic residuals, and a di- or tri-valent water-soluble metal salt is mixed with it to create a metal proteinate suitable for animal or aquaculture diets. The second patent outlines an improved method and apparatus for treating chromium-containing leather scrap. This method recovers chromium compounds and produces a protein hydrolysate through a series of mixing and hydrolyzing processes.
