ABSTRACT
Lubricating oils are used in domestic and industrial processes to increase the life of machinery. They also make the provision of energy easier and at lower cost. Growing consumption of different lubricant types that are mostly mineral-based or synthetic leads to accidental but unavoidable inflow of considerable quantities of non-biodegradable lubricants into the environment. The increase in ecological concern inspires research in the lubricant industry into raw materials from renewable sources.
