摘要： A system and method for a chromium recovery process for recovering chromium from byproducts resulting from a tannery process. A system and process for solubilizing chromium contained in the oil byproduct into the remaining water content within the oil and extracting the water from the oil with the chromium sufficiently solubilized in the water such that the chromium content in the oil is sufficiently reduced below hazardous levels.

摘要： Chromium containing protein materials are treated by processes which include the steps of: combining the material to be treated with sufficient water to effect the solubilization of the gelable protein recovered therefrom, and an alkali additive. The mixture is thereafter held at a temperature of from about 60.degree. C. to about 85.degree. C. for a period of time of from about 0.5 hour to about 8 hours. The mixture is then filtered to remove the aqueous phase, which contains solubilized gelable protein. Subsequently, water is again added to the resultant chrome-containing proteinaceous cake and at least one enzyme is utilized to hydrolyze the remaining protein thus producing a product containing solubilized partially hydrolyzed protein and insoluble chromium. After separation, the chrome in the insoluble residue may be recycled into the pickling or tanning process, and the essentially chrome-free protein components may be used as ingredients in feeds, fertilizers, and cosmetics. The processes of the present invention are used to particular advantage to treat wastes from the leather tanning industry including blue stock, chrome shavings, chrome buffing dust, chrome cakes and chrome sludges.
摘要翻译：含铬蛋白质材料通过包括以下步骤的方法处理：将待处理的材料与足够的水组合以实现从其回收的可胶凝蛋白的溶解，以及碱添加剂。然后将混合物在约60℃至约85℃的温度下保持约0.5小时至约8小时的时间。然后过滤混合物以除去含有溶解的可胶凝蛋白的水相。随后，再向所得含铬蛋白质滤饼中加入水，并使用至少一种酶来水解剩余的蛋白质，从而产生含有溶解的部分水解蛋白质和不溶性铬的产物。分离后，不溶残留物中的铬可以再循环到酸洗或鞣制过程中，并且基本上不含铬的蛋白质组分可以用作饲料，肥料和化妆品中的成分。本发明的方法特别有利于处理皮革制革行业的废物，包括蓝色原料，铬屑，铬抛光粉，铬蛋糕和铬泥。

摘要： Chrome-tanned leather wastes in a form of shavings, trimmings and grindings is first mechanically treated by cutting. The cut leather material is washed in a leaching solution containing hydrogen peroxide and potassium carbonate and/or hydrogen carbonate and/or sodium carbonate and/or hydrogen carbonate. Washing takes place in stages, using a counter-flow method, at room temperature and with occasional stirring. The exhaused leaching solution is used to prepare chrome-tannig bath directly or after acidification using sulphuric acid. After washing, leather material is rinsed using rinsing water. Residues of chromium are removed from rinsing water by precipitation with ferrous sulphate, and the filtration sludges thus obtained can be added to the exhausted leaching solution and/or chrome-tanning bath. The washed leather material is dehydrated by pressing and wet collagen product is obtained.

摘要： Bei einem Verfahren zur Herstellung eines nicht klebrigen, verrottungsfesten Werkstoffes unter Verwendung von Lederabfällen, werden Lederabfälle zu einem Lederfasern enthaltenden Ledermahlgut mit einem vorgegebenen Korngrößenbereich zerkleinert. Dem Ledermahlgut werden kollagenhaltige, natürliche, zerkleinerte Abfallprodukte und erforderlichenfalls die Klebrigkeit und/oder die Verrottung verhindernde Mittel zugemischt. Die so erhaltene Mischung wird unter Druckeinwirkung und bei erhöhter Temperatur zu einer fließfähigen Masse umgeformt, in der die Fasern des Ledermahlgutes durch den unter der Druck- und Temperatureinwirkung aus dem in der Mischung enthaltenen Kollagen entstehenden Klebstoff gebunden sind. Die Masse wird sodann zu einem formbeständigen Werkstoff auf Umgebungstemperatur abgekühlt.
