“…When the molar ratio of methanol to oil surpassed 9 : 1, glycerol separation became more difficult, leading to lowering of methyl esters yield from 97.6% to 94.5% which agrees with Amish et al [32] and Encinar et al [33]. According to Takase et al [34][35][36][37], excess amounts of methanol in a transesterification reaction leads to dilution of the oil. is phenomenon might have occurred in this study.…”

In this study, catalytic transesterification of Shea butter oil with methanol to biodiesel was carried out. The clay particle was first sieved with a 250 ml sieve and then calcined at 800μC for 8 hours in a furnace. The calcined clay was then modified with 5% each of Zn(NO3)2 and SnCl2 separately for 3 h at 60°C using incipient wetness impregnation method. The slurry compositions were then dried at 120°C overnight in an oven. The modified clay catalysts were subsequently calcined for 3 hours at 600°C. The clay that had been modified with SnO2 and ZnO was assigned SD and ZD, respectively, whereas the clay that had not been doped (control) was assigned as AC. The catalysts were characterized using X-ray Diffractometer (XRD), Brunauer Emmett Teller (BET) surface area, and Scanning Electron Microscopy (SEM). Biodiesel was then produced from each of the catalysts under varying conditions of methanol to oil molar ratio, catalyst concentration, reaction temperature, and reaction time. When compared the performances of the catalysts (activated clay modified with SnO2, ZnO, and the control), activated clay modified with SnO2 resulted in an optimal conversion yield of 99.8% under 8 : 1 methanol to oil molar ratio, 1% catalyst concentration, 60°C of reaction time in 60 minutes. The catalytic performance was affected by the basicity and surface area of the catalysts. The biodiesel produced was comparable to American and European Union standards.

“…• Government energy policies aim to increase biofuel use from 10% to 20% by 2030, break down barriers, and support a competitive market for Ghana to become a biofuel exporter. (Jumbe et al, 2009;Seglah et al, 2022;Takase et al, 2021a;Yang et al, 2014) various underutilized plant resources and agricultural wastes in biodiesel production has been overlooked, particularly in the SSA context. This oversight results in missed opportunities to improve competitiveness and sustainability by lowering production costs.…”

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

“…Transesterification process involves three consecutive reversible reactions namely, triglycerides are first converted to diglycerides, and the diglycerides are then converted to monoglycerides and glycerol backbone. Catalyst is usually used to enhance the conversion [ 54 , 55 ]. Different catalysts are used for transesterification reactions.…”

Moringa oleifera grows well in different parts of Africa, including Ghana, and throughout the world as it can tolerate moderate cold and severe drought. Dubbed as the “Miracle Tree,” Moringa has a number of nutritional, pharmaceutical, and cosmetic applications. It is also used as a cure for diabetes and various forms of cancer. Another promising use of this plant is the production of biodiesel. However, such application demands vast cultivation areas and this can lead to competition with the cultivation of crops for food, forestry, and environmental protection. Furthermore, it requires suitable cultivation schedules that favor the growth of pods containing oil-rich seeds. The present work investigates the availability of land for Moringa cultivation in Ghana to increase the energy production from the plant. The study reports on an overview of the soil, water, and climatic conditions that favor Moringa oleifera cultivation and oil production, the conversion of Moringa oleifera oil to biodiesel, and the performance of Moringa oleifera biodiesel versus mineral diesel as well as the commercial enhancement of the Moringa product.
