Abstract
The use of lime and sodium sulfide in leather making creates a lot of environmental concern. However, there is no commercial beam house process that could totally eliminate the use of lime and sodium sulfide. In this invention, a novel bio-chemical process has been standardized employing specific enzymes and non-toxic chemical that could totally eliminate the use of lime and sodium sulfide in leather processing. It has been found that the extent of hair removal and opening up of fiber bundles is comparable to that of the conventional limed leathers. Performance of the leathers is shown to be on par with conventionally leathers. The process also enjoys reduction in chemical oxygen demand and total solids load compared to conventional process.
