Abstract

This paper is aimed to apply enzyme extracted from Aloe vera plant in leather degreasing process. During a decade enormous progresses has been taken place in degreasing process. Shift from chemical-driven processes to enzyme assisted processes by the industries is an attempt to reduce or eliminate pollution loads in effluents. Enzymes are of immense use in the leather industry, the enzymes mainly used in soaking, dehairing, bating and degreasing stages of leather processing were described. Enzymes derived from plant seem to be a good alternative in today’s leather industries more specifically in degreasing. This is due to the facts that plant extract enzyme easy to extract and very effective in different process conditions. The present investigation aims at make use of two enzyme lipase and protease for the removal of fat present in the leather. Moreover, enzymatic process to reduce the consumption of chemicals and reduce the pollution loads. An extensive trial works have been conducted to assess the effectiveness of the enzymes application in degreasing process by employing standard test methods. During the process of liming, enzymes such as alkali protease and alkali lipase were used alone and in combinations in changing amounts, then optimum degreasing was conducted. Each experiment was processed till the end of tanning and to what extend the used enzymes were effective for degreasing was investigated. Results have strongly revealed that the best degreasing can be achieved with the use of 0.3% lipase enzyme. The alkali lipase and combination of alkali protease and lipase were found good in degreasing
