Method for producing leather pellets and compound granules, and use thereof
Abstract:
A method for producing leather pellets, and a method for producing compound granules from leather pellets and a polymer material, for use in molded parts or films. The leather pellets are produced through the following steps: Shavings, crust leather remnants and finished leather waste are obtained as waste products in leather production and finished leather processing; the shavings, crust leather remnants and finished leather waste are milled into ground leather stock comprising leather fibers; the ground stock is pressed into leather pellets; and the leather pellets are dried to a residual moisture content of no more than 30% by weight. The leather pellets can be mixed with a polymer material at a ratio of 10-95% by weight and bonded to one another and shaped forming compound granules. The compound granules can be used to produce molded parts by injection molding or films by calendering.
