    摘要: The invention relates to a method for producing leather pellets, to a method for producing compound granules from leather pellets and a polymer material, and to the use of such compound granules for producing molded parts or films. Said 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 as another intermediate product. Said compound granules can be used to produce molded parts by means of injection molding or films by means of calendering.

    摘要: Lederabfälle werden zuerst in Streifen oder Stücke zerschnitten oder zerquetscht. Das Zerreißen der Lederstücke oder -streifen kann in schnell rotierenden Trommeln mit Messersätzen erfolgen. Schließlich werden die Einzelfasern vom Feinmaterial abgetrennt. Die so hergestellte Ledergrundmasse besitzt ähnliche Eigenschaften wie Leder. Zusätzlich kann sie aber je nach Anwendungszweck mit weiteren Eigenschaften versehen werden. Durch die Verwendung von Abfallmaterial ist die hergestellte Ledergrundmasse billig.

    摘要: The present invention regards a process for making a solid product (18) starting from hides. The process comprises a step of arranging a sheet-like element (1) in hides, a cutting step, in which the sheet-like element (1) is cut into a plurality of cut-outs (2), a step of wetting the cut-outs (2) with water, and a mixing step, in which the cut-outs (2) are mixed with a glue (9) comprising natural resins, in order to obtain a mixed product (10). In addition, the process comprises a pressing step, in which the mixed product (10) is pressed in order to obtain a pressed semifinished product (13), and a solidification step, in which the glue (9) of the pressed semifinished product (13) solidifies in order to obtain a solid product (18) with low environmental impact and adapted to be employed in many different applications, as in the clothing field, construction field and furniture/interior design field, etc.
