Abstract

Biodiesel is one of the renewable energy sources, non-fossil. The chosen feedstock should ideally be low-cost. Using waste cooking oil can reduce synthetic biodiesel's price by up to 70%. However, biodiesel has the advantage of lower heating value and higher density, causing increased fuel consumption and NOx emissions. Biodiesel has physicochemical properties such as a more significant cetane number than fossil diesel, a high flash point, and the absence of sulfur. This study identifies the potential availability of WCO as biodiesel and summarizes recent studies on the physiochemical properties of WCO biodiesel. This study also aims to clarify the use of WCO biodiesel on engine performance and exhaust emission characteristics (H.C., CO, CO2, NOx) when this biodiesel is used. Engine type and biodiesel ratio were identified for all articles. This study also discusses the effect of adding nanoparticles on engine performance and exhaust emissions in WCO biodiesel. This study also clarifies material compatibility (corrosion, wear, and friction). The corrosion rate in various types of materials and corrosion testing methods. Finally, this paper presents the opportunity for WCO biodiesel to be very feasible to reduce fossil diesel use.

Abstract

Waste cooking oil (WCO) represents an abundant yet underutilised feedstock for biodiesel production, constrained primarily by challenges related to catalyst performance and recyclability. Conventional homogeneous catalysts, such as sodium hydroxide (NaOH) and potassium hydroxide (KOH), often suffer from deactivation after several reuse cycles due to leaching and sensitivity to impurities. In contrast, heterogeneous catalysts, including calcium oxide (CaO) and biomass-derived materials, offer promising, reusable, and environmentally benign alternatives for WCO-based biodiesel synthesis. This study presents a comprehensive bibliometric and literature review examining global research trends in biodiesel production from WCO using heterogeneous catalysts. As environmental concerns and fossil fuel depletion intensify, biodiesel has gained increasing attention as a sustainable and renewable energy substitute. A total of 974 publications indexed in the Scopus database between 2006 and June 2024 were systematically analysed to identify key research trends, influential authors, geographical distribution, and thematic clusters. Data retrieved from the Scopus database were exported in RIS format and subsequently processed using VOSviewer for bibliometric visualisation. Keyword analysis revealed dominant clusters around “WCO biodiesel” and “heterogeneous catalysts”, encompassing research topics such as transesterification, oxidation stability, performance optimisation, and corrosion behaviour. The bibliometric mapping highlights strong interconnections among research themes, particularly those associated with catalysts, transesterification mechanisms, engine performance, and emission reduction. The literature review further evaluates various types of heterogeneous catalysts including CaO, biochar, and metal- and biomass-based catalysts focusing on their synthesis routes, physicochemical properties, and optimal operating conditions. Research productivity on WCO biodiesel peaked during 2020”“2021 but declined after 2022, suggesting research saturation or shifting interest toward emerging renewable technologies. Co-country analysis identified India and Malaysia as leading contributors, while Tabatabaei et al. and Bae et al. were the most prolific authors. This study offers a holistic overview of research progress and future directions, providing valuable insights for advancing cleaner, more efficient, and sustainable biodiesel production technologies.

Abstract

Jatropha Curcas stands out as a promising plant-based feedstock, offering a non-edible oil that holds great potential as an alternative fuel to traditional diesel. Notably, Jatropha oil boasts favourable fuel properties, including a higher oil content compared to other alternatives. This attribute makes it an attractive candidate for biodiesel production. Importantly, as a non-edible oilseed feedstock, Jatropha Curcas helps mitigate concerns related to food prices and the ongoing food versus fuel debate, offering a sustainable solution to the growing energy demands. Furthermore, the plant exhibits impressive yields, with the potential to produce up to 40% oil weight per seed. This high yield not only enhances the economic viability of Jatropha-based biodiesel but also underscores its efficiency as a feedstock. The discussion extends beyond mere fuel properties, encompassing a comprehensive comparative review that delves into engine performance and emission characteristics associated with Jatropha Curcas. The novelty of this paper lies in its exploration of the crude oil aspects of Jatropha curcas, shedding light on an essential facet often overlooked. By presenting a thorough analysis of fuel properties, engine performance, and emission characteristics, the paper contributes valuable insights to the discourse on sustainable energy solutions. Moreover, it goes beyond technical aspects and provides perspectives on the current economic status, offering a holistic view of the potential impact of Jatropha Curcas in the broader context of renewable energy and economic development.

Abstract

This study investigates the optimisation and characterisation of a biolubricant produced from a castor–maggot oil mixture via two-stage transesterification. Response surface methodology using a Box–Behnken design was employed to optimise the oil volume ratio, catalyst concentration, and reaction time. The optimum conditions were a castor oil–maggot oil ratio of 50% (v/v), a catalyst concentration of 1% (w/w), and a reaction time of 2 h, resulting in a biolubricant yield of 71.43%. Ethylene vinyl acetate and ethyl-cellulose were added to enhance stability and performance. The biolubricant exhibited a viscosity index of 101.88, kinematic viscosity at 40°C of 54.57 cSt, and a flash point of 235°C, complying with ISO VG 68 and SNI 7069.9:2016 standards. These performance characteristics demonstrate favourable viscosity–temperature behaviour, adequate thermal safety, and suitability for industrial lubrication systems. The integration of mixed vegetable–insect oil feedstocks with Response Surface Methodology (RSM)–Box–Behnken optimisation, together with the incorporation of performance-enhancing additives, resulted in a biodegradable, non-toxic, and environmentally friendly biolubricant that meets standard requirements and shows strong potential as a sustainable alternative to petroleum-based lubricants for mechanical applications.
