| Summary: | In this paper, aspects regarding lubricants, their classification, their influence on the
environment and their areas of use are presented. Lubrication represents an important process
for various equipment and machines with moving parts. The correct choice of lubricant can
lead to increased energy efficiency and at the same time decrease the rate of wear of various
moving elements. We must take into account the fact that the choice of the lubricant requires
special attention because at the moment a large part of the lubricants used are those based on
mineral oils, which leads to damage to the environment, human health and high costs.
According to the above, we can turn our interest to biodegradable lubricants (based on
vegetable oils and animal fats), because they represent renewable and easily biodegradable
resources
