“…The production cost of microbial lipids (US$5.5/kg) is currently higher than the cost of lipids obtained from oilseeds, such as rapeseed (US$1.1/kg), soybean (US$1.64/kg), palm (US$0.19/kg), jatropha (US$0.39/kg), and castor (US$0.14/kg) . Nevertheless, there are different factors, such as cheaper feedstocks, better fermentation processes, different culture modes, and strain development, which can be used to improve yields to make it technologically and economically feasible .…”

The use of lignocellulosic biomass biofuels is an attractive alternative because they do not put food safety at risk, they are a renewable source, and their use is limited. The use of microorganisms has now become more widespread to take advantage of the carbohydrates present in this raw material (cellulose and hemicellulose) and the products of its hydrolysis (glucose, xylose, arabinose, galactose, and mannose). The fatty acids obtained from oleaginous microorganisms are potential sources for the production of drop‐in biofuels. Rhodosporidium sp. is an oleaginous yeast that accumulates up to 70% of its biomass in the form of lipids and is highly adaptable to different types of substrates. This review discusses the different factors and challenges (genetic modification of strains, pretreatments, and inhibitor effects) in obtaining lipid from lignocellulosic biomass using Rhodosporidium sp. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Using various methods, such as the non-catalytic supercritical method [20,21], the biox process [22], microwave heating [23], membrane technology [24], reactive distillation [25], and ultrasonication [26], the transesterification process for biodiesel production can also be performed.…”

“…In the biox process, a co-solvent tetrahydrofuran (THF) is used to accelerate the reaction by solubilizing methanol. Methanol (337.7 K) and THF (339 K) have similar boiling points, resulting in the removal of excess solvents in one step after the completion of the reactions [22]. Using this process, a conversion of oil feedstock with a high amount of FFA (to 10%) in biodiesel is possible in a two-step, single phase, continuous process at atmospheric pressures and a near-ambient operating temperature of 303.15 K [31].…”

Biodiesel Production Using Solid Acid Catalysts Based on Metal Oxides

et al. 2020

The development of solid acid catalysts, especially based on metal oxides and different magnetic nanoparticles, gained much awareness recently as a result of the development of different nano-based materials. Solid acid catalysts based on metal oxides are promising for the (trans)esterification reactions of different oils and waste materials for biodiesel production. This review gives a brief overview of recent developments in various solid acid catalysts based on different metal oxides, such as zirconia, zinc, titanium, iron, tungsten, and magnetic materials, where the catalysts are optimized for various reaction parameters, such as the amount of catalyst, molar ratio of oil to alcohol, reaction time, and temperature. Furthermore, yields and conversions for biodiesel production are compared. Such metal-oxide-based solid acid catalysts provide more sustainable, green, and easy-separation synthesis routes with high catalytic activity and reusability than traditionally used catalysts.

“…The cost of biodiesel is widely regarded as a principal barrier in the development of the sustainable energy process. It has been reported that the feedstock cost is the major factor contributing to the final biodiesel cost and this cost represents approximately 70-95% of the total cost of biodiesel production [46][47][48]. Therefore, several efforts have been devoted to explore and select an ideal feedstock for economically viable biodiesel production.…”

“…However, the use of non-edible oils for biodiesel production cannot be the ultimate solution for a sustainable energy process as large plantation land areas would be required for large-scale non-edible oils production. This may disturb the entire animal and plant ecosystems [45,47]. Therefore, it is important to search for cost effective biodiesel feedstock such as waste cooking oil, which is cheap and easily available all over the world.…”

Currently, the fossil fuel sources are the major contributors to the world's energy mix. However, these conventional energy sources are depleting very fast due to their finite nature and extensive uses. An addition to their finite nature, environmental problems related to their uses are getting progressively worse and worse, initiating challenging debates for scientific communities. Biodiesel, a renewable fuel, has shown promising prospects due to its strong socioeconomic benefits and motivations in most of the countries of the world. Bifunctional heterogeneous catalysts are strongly recommended for biodiesel production from different feedstocks to simplify the process. This review highlights the challenges and opportunities associated with the heterogeneous catalysts and some recommendations to design an efficient bifunctional heterogeneous catalyst for economical biodiesel production from waste cooking oil.
