Résumé : |
Among the reuse and/or disposal possibilities for chromium tanned leather waste (CTLW), one in particular stands out: hydrolysis. This process not only allows chromium recovery, but also the extraction of its protein, as collagen hydrolysate or as gelatin. CTLW hydrolysis has been performed for decades. However, industrial application of this important alternative has not been widespread. Thus, this review presents how CTLW alkaline hydrolysis has been evolving over the years; how the process can be adjusted to increase protein extraction yield and to produce better quality products. Finally, it reviews in which areas its products have already been tested. Here, researchers may find practical process information that might allow them to focus on the most important current issue for CTLW hydrolysis: how to upgrade this process to an industrial scale. |
