Introduction

It is an eco-friendly, sludge free liming process resulting in improved quality of leather. The process involves liming the well-soaked raw hides and skins wherein, unlike the conventional process, no lime sludge is formed in the lime bath, thereby reducing the load of beam house effluent. The unique feature of the process is to carry out liming, avoiding completely the use of lime.
