From concept to practice: manufacturing of bio-lubricants from renewable resources

The annual global oil market is about 40 million tons, including vegetable oil-based lubricants, and modified esters currently account for only about 10–15%. Half of these lubricants are getting into the atmosphere, water, and soil. That is why environmentally friendly lubricants present a rapidly expanding branch of industrial lubricants, which will become increasingly important over the next century. The aim of this work is to make a comparative analysis of fats. Animal fats and fish oil which are inappropriate for food industry were selected for the investigation purposes. The base and ferment hydrolysis were made in order to separate free fatty acids from selected fats. The produced esters, animal fats, and fish oil were studied by evaluation of their physicochemical properties. As a result, octyl esters which were produced from animal fats and fish oil are ascribed to 22, fish fats to 32, and animal fats to 46 classes.
