During the last few decades new materials and technologies have being studied and applied in order to reduce the ecological impact of leather production. Severe restrictions imposed by the pollution control authorities on the disposal of chromium, total dissolved solids and chlorides in tannery effluents have forced the tanners and researchers to look for eco-benign pickling and tanning processes. In this study, we would focus on the novel process development of pickling with the presence of oxazolidine based product. Investigations indicated that oxazolidine is a potential material to replace neutral salts in pickling and, realize high chrome exhaustion in the subsequential chrome tanning.
