Vegetable tannage is an eco-friendly method compared with environmental polluting chromium based method of tanning that is commonly used in commercial tanning and which prevents the collagen fibrous protein in animal skins from putrefaction and produces hydrothermal stable product commonly known as leather. Thus study was conducted to improve the tanning efficiency of locally available tanning in the Sudan 'Garad', applying blending method, physico chemical properties of 'Garad', bark and leaves of 'Neem' and 'Karkady' bark was determined, hide powder method was used in determining the tannins content whereas the analysis t-test and Anova were used to compare the mean values of the physico-chemical properties of vegetable tanning materials, the physico-chemical properties results of 'Neem' bark, crushed 'Garad' and pure powder were found to be acceptable and utilized as raw materials for commercial manufactory purpose, screening results of 'Karkady' calyxes and bark show that they contain oxalate organic salts 0.5% which were used to chelate the iron from the tanning liquor the results showed high efficiency, whereas used 5% dry leaves powder of 'Neem' at 60°C eliminated the mould growth for one month and also dropped the viscosity to opposite level and subsequently the liquor of improved indigenous tanning material was produced by blending 80% Acacia nilotica pods with 20% azadirachta indica barks' and then in spray-drying, various physico chemical properties were studied and compared with those of conventional indigenous and myrobalan tanning materials.
