“…The availability of the WCO is one of the key reasons it is garnering more interest in this field. Most importantly, the high cost of using virgin oils is recently also instigating such moves since WCOs are relatively very cheap 47,48 . Biolubricants that are produced from WCO based biodiesel have pronounced enhanced properties (ie, viscosity index, flash point, and pour point) compared with the ISO VG10 base oil standard, making it highly smart and a sustainable substitute to fossil fuel‐based lubricants 69…”

Summary The growing concern and limitations for existing lubricants have driven the need for biolubricants, extensively proposed as the most suitable and sustainable lubricating oils. Biolubricants are generally synthesized from various bio‐based sources, including vegetable oils, microbially derived oils, waste cooking oil, etc. They are promising commodities and advantageous to mineral‐based analogues due to their exceptional properties like their lubricity, biodegradability, reduced toxicity, and reduced volatility. Yet, their utilization as lubricants is constrained due to their relatively poor cold‐flow and thermo‐oxidative stability uncertainties even after being chemically modified. Hence, many chemical modification pathways have been reported to overcome this limitation, with the most exploited approaches being esterification and transesterification. This modification pathway enhanced the thermo‐oxidative stability and the cold‐flow properties of these bio‐based oils, increased the yield, and enhanced the quality of the lubricants. With this in mind, this paper reviews up‐to‐date works conducted in this area and critically report the advancement in esterification and transesterification production of biolubricants. The study further reviews the latest published literature, current updates, and future perspectives related to the synthesis of biolubricants. Also, the review highlights the significant factors that govern the entire reaction process, selection criteria of renewable feedstocks, and the tribological performance of biolubricants.

“…Epoxidation is also proved to be an effective way of plant oil modication, which can be carried out under gentle reaction conditions (<100 C and atmospheric pressure). [40][41][42][43] In this study, a new "epoxidation & combination" method of producing low-cost WCO-based wax was proposed for the rst time. In this approach, WCO was epoxidized to form E-WCO, and then combined with special modier, SA, to form cost-effective wax material that can replace the commercial SW (Fig.…”

“…The biolubricant produced is renewable, biodegradable and ecofriendly [ 25 ]. Bashiri et al has reported a similar study by chemically modifying sunflower waste cooking oil to prepare biolubricant as a potential feedstock over mineral oil for industrial application [ 26 ]. Madankar et al have given a green approach for preparing biolubricant with improved tribological properties from epoxidized canola oil using amberlite IR 120 as catalyst followed by ring-opening with different alcohols [ 27 ].…”

Developing eco-friendly formulations using waste cooking oil as renewable biomass is of great interest and commercial importance in the fuels and lubricant industry. This manuscript reports novel study on preparing a biolubricant formulations as WCO-1, WCO-2 and WCO-3 by blending the curcumin extracted soybean waste cooking oil in three different compositions viz 10%, 20%, 30% v/v with the mineral base oil N-150. Curcumin was extracted as a natural antioxidant in 0.5 wt% waste cooking oil to inhibit thermal oxidation. This study comprises a detailed analysis in terms of tribological, rheological and thermophysical characteristics such as viscosity, viscosity index, pour point and flash point parameters of the biolubricant by standard ASTM methods. Further, tribological and rheological analysis was done by the four-ball wear tester and Anton Paar, MCR-72, respectively. The thermophysical evaluation of WCO formulated biolubricant has shown excellent properties. The viscosity index of the formulated biolubricant increases with an increase in the concentration of waste cooking oil. In contrast, the pour point has also been depressing at lower temperature conditions. Thus, WCO based biolubricant was found to be more effective at extreme temperature conditions than the mineral base oil (N-150). Rheological studies have indicated the non-Newtonian behaviour of the biolubricant with an increase in shear rate. Whereas, tribological analysis demonstrates that wear scar diameter has significantly reduced from 0.685 to 0.573 mm, and the coefficient of friction decreased from 0.117 to 0.080 with respect to the mineral base oil. Thus, a straightforward green approach has been discovered by directly utilizing waste cooking oil for biolubricant formulation. Graphical abstract
