“…Nevertheless, when evaluating the cost of whole biodiesel process, the purification procedure is critical to purifying the purified biodiesel before usage in the diesel engines. Therefore, a future research may investigate the different types of wet washing, dry washing, membrane separation, and ion exchange for removing residual catalyst, residual methanol, and residual glycerol in biodiesel after the transesterification process [62] .…”

“…Biodiesel-fatty acid methyl ester (FAME)-is an alternative fuel produced from vegetable oils, animal fats, waste fats, and other fatty feedstocks with suitable characteristics and properties. Typical feedstocks for biodiesel production are rapeseed oil, soya oil, sunflower oil, palm oil, and oil obtained from microalgae [21]. Cattle/sheep/poultry tallow, animal oil, used cooking oil, fish oil, jatropha oil, and coke have also been used [22,23].…”

The supply of waste glycerol is rising steadily, partially due to the increased global production of biodiesel. Global biodiesel production totals about 47.1 billion liters and is a process that involves the co-production of waste glycerol, which accounts for over 12% of total esters produced. Waste glycerol is also generated during bioethanol production and is estimated to account for 10% of the total sugar consumed on average. Therefore, there is a real need to seek new technologies for reusing and neutralizing glycerol waste, as well as refining the existing ones. Biotechnological means of valorizing waste glycerol include converting it into gas biofuels via anaerobic fermentation processes. Glycerol-to-bioenergy conversion can be improved through the implementation of new technologies, the use of carefully selected or genetically modified microbial strains, the improvement of their metabolic efficiency, and the synthesis of new enzymes. The present study aimed to describe the mechanisms of microbial and anaerobic glycerol-to-biogas valorization processes (including methane, hydrogen, and biohythane) and assess their efficiency, as well as examine the progress of research and implementation work on the subject and present future avenues of research.

Second-generation biodiesel, which is produced from essential oil plants, has important advantages, including a high yield of biofuels and the potential to reduce greenhouse gas emissions. The goal of this research was to examine the profile of original and review articles on biodiesel production from essential oils using bibliometric analysis. The search strategy identified 186 relevant and available peer-reviewed publications from 1981 to 2023, which were downloaded from the Web of Science (WoS) database. The retrieved documents were analyzed using VOSviewer. China was the predominant country publishing those documents, followed by the United States, India, Australia, and France. The keyword cluster analysis indicated the presence of 10 main research topics: diesel, fuel, and engine performance; extraction of lipids from microalgae; biofuel production from essential oils; green chemistry; the pyrolysis process; bioethanol production from renewable raw materials; obtaining biodiesel from essential oils; essential oil extraction; obtaining biofuels; and supercritical fluid extraction for fuels. The top three authors were Rahman, S. M. A., Cantrell, C. L., and Zheljazkov, V.D. The results showed that study topics such as different biodiesel raw material sources, biodiesel conversion technology, and the performance and emission characteristics of second-generation biodiesel are gaining popularity, with the goal to achieve a sustainable and clean environment.
