TANNING EFFECT OF POMEGRANATE PEEL AND OLIVE LEAF TANNIN COMBINATION

Agro-industrial wastes possess highly-valuable bioactive compounds. Recently, they have been taken into account as an alternative source that can be used raw material for various industries. Such approach help to reduce both production cost and pollution load. In this study, the usability of pomegranate peels olive leaves, defined agricultural industrial residues, a combined tanning agent in leather industry was investigated. For purpose, first all leaves were extracted determining their tannin contents then process evaluation ability. Shrinkage temperature (76.5 °C) resulted from combination mechanical properties tanned revealed evaluated alternative, satisfying industry.
