Latest Patents
One of Erickson's latest patents is a method of producing a metal nutrient for animal feed. This invention involves creating a leather hydrolysate metal proteinate, which serves as a metal nutrient for animal diets. The process includes heating chrome tanned leather scrap in an aqueous solution with an alkali material, resulting in a water-soluble, low molecular weight protein hydrolysate. The hydrolysate is then oxidized to eliminate any undesirable organic residues from the tanning process, and a metal salt is mixed in to create a metal proteinate that can be used in animal or aquaculture diets.
Another significant patent is the method and apparatus for treating chrome leather waste. This invention provides an improved approach to recover chromium compounds from leather scrap while producing a protein hydrolysate. The leather scrap is mixed with an alkali metal solution in a reaction vessel, where it undergoes hydrolysis. The resulting hydrolyzed mixture contains suspended chromium particles, which can be separated and reused in the tanning process. This innovative method not only recycles valuable materials but also enhances the efficiency of leather waste treatment.
