What are biodegradable lubricants?

This means the biochemical decomposition of organic chemical compounds accelerated by microorganisms. Microorganisms such as bacteria, fungi, protozoa, etc. bring about biological degradation through what is termed bio-oxidation. This occurs in several stages, producing CO2, water, protein cell material and multiplication of micro-organisms.
