Leather making is a very long process and consists of many different chemical and mechanical processes. The common raw materials of leather industries are skins or hides, chemicals and water. Fleshing is one of the processes in leather tanning which aims to remove the remaining meat and fat that is still attached to the skin or hide. The treatment of fleshing waste results 13.733, 8.073 and 8.5 for moisture content, ash content and pH respectively. These properties indicated that the high amount of water removed by drying and the removal of different salts and basic chemicals. The different yield of fat with minimum 6.46 and maximum value of 14.867 by different solvents indicate the requirement of optimization of process for fat extraction. Chemical property values 10.262, 165.527 and 249.33 respectively for acid value, iodine value and saponification value of fat compared to other sources (fish oil) shows that fleshing waste can be a source of leather fatliquor. In fatliquor characterization a high iodine number shows that the product is dry oil, has high penetration power. Similarly saponification value is also indicating high probability to be a source of fatliquor. Properties of sulfated fatliquor were characterized to compare with commercial fatliquor. The product was used in leather processing in post tanning process. Organoleptic properties done by visual examination of experienced chemists was similar in between experimental and control leather garments, this properties indicate the probability of producing fatliquor from lime fleshing waste. Collectively the results of the current study pointed out the efficiency of extracting fat from fleshing waste and converting it into fatliquor in achieving distinctive environmental and economic benefits. It is recommended that further optimization of the extraction process depending on the factors (temperature, solvent type and time) increase the quality of sulfated product.
