An overview of pumice stone and eco stone in denim washing industry in case of sustainability

Abstract

In denim washing industry pumice stone is a very popular material in enzyme or jumping process. Pumice stone is less costly and that's the only reason behind it's higher application. But pumice stone creates more sludge in ETP & requires more water in process which is not sustainable. Also for usage of pumice stone there is a higher possibility of damage issue in case of very light wash. In this study Eco Stone were used instead of Pumice stone to observe it's all kinds of outcome against Pumice stone with its sustainability. Because Eco stone require less water and create less sludge as its corrosion is lesser than Pumice stone. And for its smooth surface the possibility of physical damage of garments is lower.
