الملخص

The aim of this research was to enhance the Sudanese leather process usinglocal tanning agent, to apply the ideas of cleaner technology in Sudan, toreduce environmental pollution generated by chromium and to produce anew type of leather with a specific identity that can compete easily in theinternational market.After the process of tannage, almost 25% by weight of input raw materialare wasted. The occurrence of such a large amount of waste presentseconomic and mainly ecologic problem for this industry; thus substantialglobal effort is given to development of improved technologies for thedisposal of chromium tanned waste. (Acacia nilotica) Garad used with amineral chromium and aluminum to limit the consumption of undesirablechromium.In the experimental work 24 pieces pickled cattle hides were processed ineight trials, in each trial three pieces pickled cattle hides were treated in pilotdrum with speed of 8 rpm. Four trials were treated with 30% garad astannage and different percentages chromium of (1,2,3,4%) as retannage,other four trials were treated with 30% garad as tannage and differentpercentages aluminium of (1, 2, 3, 4%) as retannage.The leather produced was analysed for physical testing, including thickness,tensile strength, percentage elongation at break, load at grain crack, load atgrain burst and shrinkage temperature. And chemical analysis includingmoisture content, ash content, fat and chrome contents. The results werecompared with the standard specification and found to be satisfactory.
