Abstract:
The potential application of bio‐based ester oils for use as lubricants in metal working has been investigated for sustainable production processes in the future. When waste edible and animal fats came into focus as starting materials, it was already proven, that ester oils produced from plant fats performed very well as cooling lubricants. Waste fats were first characterized by analyzing and monitoring samples for one complete year. Inorganic and organic contaminations were found to be low and without seasonal variations. Fatty acid methyl esters (FAME) were produced by transesterification of the waste fats and they were separated into fractions with saturated FAME or unsaturated FAME by fractional crystallisation (winterisation). Further transesterification with 2‐ethylhexanol led to products that could be successfully tested as lubricants. The development of an extraction process aimed at the recycling of oil containing grinding mud by enabling the recirculation of lubricating oil and reutilization of oil‐free metal chips.
