“…The utilization of metal‐organic frameworks as heterogeneous catalysts appears promising for biodiesel production (Garg et al, 2023). Solid metal oxide catalysts effectively catalyze triglyceride conversion into fatty acid methyl esters (Aziz et al, 2020; Tavizón‐Pozos et al, 2021), while zeolites show promising results in transesterification, particularly with various feedstocks like waste cooking oil and nonedible oils (Abukhadra et al, 2019; Gadin et al, 2023).…”

The world is currently dealing with an energy crisis, primarily due to heavy reliance on finite fossil fuels and the associated rise in energy demand. In response to this crisis, replacing heavy reliance on finite fossil fuels with biodiesel has gained attention as an alternative solution. Sub‐Saharan African (SSA) biodiesel studies have traditionally focused on improving transesterification but overlook socio‐economic, policy, and institutional impacts on production sustainability. To address this gap, this study comprehensively reviews the sustainability of transesterification‐based biodiesel production from nonedible feedstocks in SSA. The study's incorporation of socio‐economic factors, policy considerations, sustainability concerns, and institutional frameworks reveals the complex prospects and challenges facing biodiesel production in SSA. The findings reveal that sustainability challenges in SSA stem from a lack of an integrated approach, resulting in conflicting local and global policies. The study determines that neglecting socio‐economic factors, policy considerations, sustainability concerns, and institutional frameworks weakens regional biodiesel production sustainability. Evidence from the study emphasizes the role of an integrated approach in promoting biofuel production, establishing markets, and improving the livelihoods of the region's population. Furthermore, the review shows that transesterification can yield biodiesel with comparable physical properties to conventional diesel, making it a wide region's favored option.This article is categorized under: Human and Social Dimensions > Energy and Climate Justice Sustainable Energy > Bioenergy Sustainable Development > Goals

“…The use of zeolites in transesterification reactions has been widely studied as a support for alkaline metals, alkaline Earth metals, transition metals, or enzymes. [81][82][83] Even with that significant number of publications, SrO supported on natural zeolite (NZ) catalytic systems is particularly scarce. Mierczynski et al 84 tested MgO, CaO and SrO supported on a calcite-rich modernite natural zeolite calcined at 400°C in the transesterification of canola oil at The activity was significantly enhanced by supporting the AEMO on NZ.…”

SrO has attracted attention for its use as a heterogeneous catalyst in producing biodiesel from transesterification owing to its high alkaline character and low solubility in methanol. In studies conducted in this decade, reaction conditions such as the methanol–oil molar ratio, reaction time, catalyst loading and temperature have been optimized in these systems. Furthermore, several works have been carried out to improve the physicochemical properties and increase the leaching resistance of this material. Thus, the new trends in using SrO in transesterification reactions are that this oxide should be supported or combined with Al2O3, TiO2, ZrO2, or Fe2O3, CaO, metal–organic frameworks, zeolites or La2O3. It has been observed that strontium can form mixed crystalline phases with these oxides by increasing the (M2+O2−) pairs and Lewis basicity of the oxygens, resulting in increased basicity and catalytic activity. Moreover, the transition metal oxides may provide Lewis acidity. Hence, these strontium‐containing catalytic systems have demonstrated a bifunctionality that can perform esterification and transesterification reactions at the same time. In addition, the combination of these oxides decreases the leaching of the catalyst. Other materials such as metal–organic frameworks, zeolites, and La2O3 have been studied as SrO supports, showing that they can be used in oil transesterification reactions.

“…In the second step, transesterification of triglycerides with methanol was performed by thermal activation using solar radiation as a light source and NaoH. It was shown that the biodiesel obtained from this process has all the international requirements for application as a fuel [56].…”

There is a growing demand for use of alternative clean energy as against fossil fuel. In trying to meet these demands, researchers are investigating various approaches towards delivering affordable clean energy from the abundant biomass in our environment, including biodiesel. Esterification of oils is one of the advanced methods of oil technology, which changes the main structure of glycerides without causing chemical changes in the fatty acid that forms the structure of triglycerides. Biodiesel is an alternative fuel that is renewable and produces less harmful gases than fossil fuels. Among the sources of biodiesel are vegetable oils and animal fat. The use of free solar light sources is significant for producing clean energy and reducing the economic costs of photocatalysts. In the present work, these issues have been addressed and the work done has been reviewed. The focus of this research is to examine the studies conducted to investigate the efficiency of biofuel production from edible and non-edible oils using photocatalysts. Studies have shown the production of biodiesel with high efficiency. High efficiency for biodiesel production from this method shows the future use of this fuel.
