Generally, only 60-80% of the offering chrome is effectively utilized and chrome-contained leather shavings and effluent is discharge into the environment, which triggers to severe environmen- tal pollution. Hence, finding a sustainable solution to reduce chrome disposal is a prime challenge for global tanners and researchers. This review focuses the methodology of cleaner chrome tanning, that is, integrated chrome tanning process, high exhaustion agents or auxiliaries based on chemical materials are discussed in this review.
