Research team in Argentina excited about enzyme technology
23/03/2016
The group of specialists leading the investigation has trialled the use of these non-harmful enzymes partially in place of sodium sulfide. Researchers believe that this could lessen the amount of hydrogen sulfide released during unhairing and result in a smaller environmental footprint.
Enzymes have long been used in the unhairing of hides, primarily as a catalyst alongside sodium sulfide, but the team in Argentina is now targeting a 50% reduction in the use of sulphur. In the long-term it believes that the enzymes could replace sodium completely in the unhairing process in tanneries.
