摘要

Conventional leather processing generally involves a combination of single and multistep processes that employs as well as expels various biological,inorganic,and organic materials.It involves nearly 14-15 steps and discharges a huge amount of pollutants.This is primarily due to the factthat conventional leather processing employs a "do-undo" process logic.In this study,the conventional leather processing steps have been reversed to overcome the problems associated with the conventional method.The charges of the skin matrix and of the chemicals and pH profiles of the process have been judiciously used for reversing the process steps.This reversed process eventually avoids several acidification and basificationeutralization steps used in conventional leather processing.The developed process has been validated through various analyses such as chromium content,shrinkage temperature,softness measurements,scanning electron microscopy,and physical testing of the leathers.Further,the performance of the leathers is shown to be on par with conventionally processed leathers through bulk property evaluation.The process enjoys a significant reduction in COD and TS by 53 and 79%,respectively.Water consumption and discharge is reduced by 65 and 64%,respectively.Also,the process benefits from significant reduction in chemicals,time,power,and cost compared to the conventional process.
