Lubricants are essential in engineering, however more sustainable formulations are needed to avoid adverse effects on the ecosystem. Bio-based lubricant formulations present a promising solution. Biolubricants: Science and technology is a comprehensive, interdisciplinary and timely review of this important subject. Initial chapters address the principles of lubrication, before systematically reviewing fossil and bio-based feedstock resources for biodegradable lubricants. Further chapters describe catalytic, (bio) chemical functionalisation processes for transformation of feedstocks into commercial products, product development, relevant legislation, life cycle assessment, major product groups and specific performance criteria in all major applications. Final chapters consider markets for biolubricants, issues to consider when selecting and using a lubricant, lubricant disposal and future trends. With its distinguished authors, Biolubricants: Science and technology is a comprehensive reference for an industrial audience of oil formulators and lubrication engineers, as well as researchers and academics with an interest in the subject. It provides an essential overview of scientific and technological developments enabling the cost-effective improvement of biolubricants, something that is crucial for the green future of the lubricant industry.

A Comprehensive Review of Developing Environmentally Friendly Lubricants A push from environmentally savvy consumers along with recent changes in governmental regulations have paved the way for a marketplace of products with high levels of environmental performance. Fueled by the growing demand for biobased lubricants, Environmentally Friendly and Biobased Lubricants highlights the development of environmentally friendly additives that are compatible with environmental regulations and describes the approaches being used in this emerging area. Derived from research topics shared over the years at various technical sessions of the Society of Tribologists and Lubrication Engineers (STLE) Annual Meetings, the book includes a critical assessment of gaps and weaknesses in the field of environmentally friendly fluids and biobased lubricants. Each chapter is written by authors selected from the environmentally friendly fluids and biobased lubricants sessions of STLE and also incorporates input from prominent researchers invited to take part in the book. Expert contributors discuss the control, production, usage, and disposal of lubricants; factor in related policies, laws, and regulations around the world; and include case studies demonstrating the uses and values of commercially viable biobased lubricants. The book is divided into five sections that cover advanced environmentally friendly base oils and feedstocks, biobased hydraulic lubricants and biodegradability, chemically/enzymatically modified environmentally friendly base oils, vegetable oil–based environmentally friendly fluids, and additives for environmentally friendly fluids.

Graphical abstract: Highlights: Lipase extract from C. rugosa was found very useful to produce biolubricants from soybean oil. The free lipase cannot be used at medium scale. The immobilization in Accurel enabled the reaction maintaining the good properties of the enzyme. The immobilized lipase could be reused several reaction cycles. Abstract: Three commercial lipases, Lipomod 34MDP (free lipase from Candida rugosa ), Lipozyme RM IM (immobilized lipase from Rhizomucor miehei ) and Novozym 435 (immobilized lipase B from Candida antarctica ) were evaluated as catalysts in the production of biolubricant base oils. This was accomplished via the esterification of free fatty acids obtained from soybean-oil hydrolysis and different polyols (neopentyl glycol, NPG; trimethylolpropane, TMP; and pentaerythritol, PE). Reactions carried out with free C. rugosa lipase showed the highest conversions for the three polyols (97% for NPG, 100% for TMP and 55% for PE) after 24h, while Novozym 435 and Lipozyme RM IM resulted, respectively, in 65% and 92% for NPG, 15% and 39% for TMP and 1% and 0% for PE. Then, Accurel MP1000 (a microporous polypropylene support, PP) was used to immobilize the C. rugosa lipase; enzyme loading used was 0.3mg/g. The zymography analysis showed that the protein band of 60KDa present in the C. rugosa lipase extract was the main protein responsible for the extract activity in the biolubricant synthesis and it was successfully immobilized onto the support. The immobilized lipase (34MDP-PP) showed conversions of 99% for NPG and 92% for TMP, after 24h of reaction, maintaining the results obtained with the free enzyme. The 34MDP-PP could be reused for six consecutive reaction cycles without a reduction in the final conversion, using NPG and TMP as substrates. Using Lipozyme RM IM, the conversion decreased from 92 to 56% after six consecutive reactions. The soybean esters of NPG and TMP showed good viscosity indexes, higher than 200.

This book is an excellent guide to biobased and biodegradable polymeric materials. It summarizes current knowledge on polymer degradation mechanisms and provides insight into recent, state of the art syntheses of (bio)degradable polymers. The book captures the shift that is currently observed in polymer industries, which takes the industry from a strict petroleum-based business to an industry that starts to incorporate biobased raw materials and seeks actively to manufacture materials that are environmentally benign. The book describes various aspects of current polymer research with special emphasis on natural polymers, syntheses and modifications of polyesters and characterization technologies that allow to elucidate degradation mechanisms. The understanding of polymer degradation is not limited anymore to hydrolytic processes, this book captures new approaches to the degradation of plastic materials ranging from photodegradation to the regulation of genes of polymer-degrading microorganisms. A profound part of the book is dedicated to poly(lactic acid) a polymer that is now produced in large scale from renewable resources, the modification, copolymerization, application and engineering of this material is discussed in detail and a comprehensive review is provided.

Used lubricating oil is a valuable resource. However, it must be re-refined mainly due to the accumulation of physical and chemical contaminants in the oil during service. Refining Used Lubricating Oils describes the properties of used lubricating oils and presents ways these materials can be re-refined and converted into useful lubricants as well as other products. It provides an up-to-date review of most of the processes for used lubricating oil refining that have been proposed or implemented in different parts of the world, and addresses feasibility and criteria for selecting a particular process. The book begins with an overview of lubricating oil manufacturing, both petroleum-based and synthetic-based. It reviews the types and properties of lubricating oils and discusses the characteristics and potential of used lubricating oils. The authors describe the basic steps of used oil treatment including dehydration, distillation or solvent extraction, and finishing. They explore the combustion of used oil for use as fuel, covering chemistry and equipment, fuel oil properties, and combustion emissions. The book considers alternative processing options such as refinery processing and re-refining. It also reviews the major refining processes that have been suggested over the years for used oil. These include acid/clay, simple distillation, combinations of distillation and hydrogenation, solvent extraction, filtration, and coking processes. The book addresses economic, life cycle assessment, and other criteria for evaluating the attractiveness of an oil recycling project, examining various costs and presenting an economic evaluation method using an Excel spreadsheet that can be downloaded from the publisher’s website. The book concludes with a chapter offering insights on how to choose the most suitable process technology.
