Biolubricants are a viable alternative to synthetic lubricants because they are produced from organic materials such as plant oils, waste oils and by-products. Renewable biolubricants are the subject of research because of their biodegradability, eco-friendliness, and favorable socioeconomic consequences to counteract imitations of synthetic lubricants. Biolubricants have thus emerged as an ideal substitute for mineral oil-based lubricants, as significant economic and environmental acceptability has been received over the last few decades and it has been estimated that there would be a further steady growth in its demand over the next few decades. Furthermore, biolubricants’ high-quality lubricating properties, high load carrying ability, long service life, and fast biodegradability have expanded the recent interest. These lubricants can be derived from different sources of vegetable oils, non-edible oils, waste cooking oils (WCO) and microbe-derived oils. Among all these sources, the use of WCOs and microbe-derived oils have received immense interest and provide superior quality biolubricants.
This outstanding new volume covers the prospects and processing of feedstocks for biolubricants, extraction techniques, new advancements in the field of bio-based lubricants, epoxide lubricants, hydrogenated lubricants, microbial-based biolubricants, nano-biolubricants, polyester-based biolubricants, lubricants from waste oils and waste materials, its economic and environmental acceptability and biorefinery approaches. The book will be helpful to industry professionals and engineers of all types, students, and other stakeholders working in the field of lubricant, chemical engineering, mechanical engineering and material science, tribological sectors and biorefinery industries. It will also be of great interest to new start-up companies working in the area of processing feedstocks for biolubricant production and end use application, biorefineries, valorization of biolubricant waste, and in the recycling industries.
