Several researchers have reported the prospects of biofuel commercialization in several countries across the globe. With over 400 million tons of biomass and 150 million tons of agro-waste produced annually in most developing countries, the prospect of biofuel commercialization looks promising. However, it is crucial to adopt a forward-thinking approach and anticipate potential challenges that may arise, building upon the lessons learned from current obstacles. This paper review addresses the current issues that have discouraged some developing countries against embracing biofuels as an economical tool to mitigate poverty. Also, future challenges that may scuttle biofuel commercialization in developing countries was discussed to provide a workable blueprint towards wealth creation. This review identified policies and political unwillingness as fundamental challenges that must be overcome in developing countries to attract investors. Other identified salient challenges include mono-economy, poor technical know-how, poor technology, government hypocrisy, lack of funds, sustainable biomass resources, inadequate farmland, poor policies, and weak infrastructure. It is recommended that conscious short- and long-term planning be implemented to actualize biofuel commercialization in developing

Internationally exploited lubricants are derived from coal and petroleum. Due to their high consumption and effects of their long-term pollution on the environment, it is imperative to use renewable and cheap feedstock for the synthesis of bio-based lubricants. This study presents the synthesis and optimization process of Ethylene Glycol (EG) based bio-lubricant from palm kernel oil. Palm Kernel Methyl Ester (PKME) was synthesized at a reaction time of 60 min, a molar ratio of oil: methanol 1:6, a temperature of 60 oC, and catalyst of 1 % wt/wt (in-situ transesterification) via reactive extraction. Box–Behnken design (BBD) in response surface methodology (RSM) was applied to this experimental layout. The effects of molar ratio, reaction time, and temperature on the synthesis of palm kernel biolubricant (PKBL) were evaluated. The PKBL structure was characterized by Fourier Transform Infra-Red (FT-IR) and Gas Chromatography-Mass Spectrophotometer (GC-MS) analysis, showing favorable lubricating properties. The PKME yielded 94.53 wt% based on the weight of the oil, while transesterification of the in situ derived PKME with EG yielded 93.08 wt% of the EG ester (Biolubricant). The maximum biolubricant recovery was 81.48 wt% obtained at a molar ratio of 3:1, time of 2.48 h, and temperature of 135 oC. The temperature and mole ratio were established to be the most significant terms. PKBL characteristics conformed to ISO VG criteria and had high potential for biolubricant feedstock.
