“…The major processing conditions that affect the yield of transformation and have been recognized by many studies include the methanol/oil molar ratio, amount of catalyst, reaction temperature, and reaction time [67][68][69][70][71]. The methanol's boiling point restricted the reaction temperature.…”

This study focuses on the optimization of biodiesel synthesis using non-edible hempseed oil as the feedstock. The Response Surface method was used to find the best methanol:oil molar ratio, catalyst concentration, reaction temperature, and reaction duration for the transesterification process. The center composite design experimental design was used to make the design. A total of 30 cycles were conducted to adjust the four parameters at five different levels in order to optimize the biodiesel production process. It was found that the best conditions for transesterification of hempseed oil were a KOH catalyst concentration of 0.80 wt%, a molar ratio of 7.41:1, a reaction time of 62.83 minutes, and a reaction temperature of 61.92 °C. Under these optimized reaction conditions, the predicted biodiesel yield was 95.57%, while the experimental yield was 95.24%. The biodiesel produced using the optimized parameters was analyzed for its properties, and the findings demonstrated that it met the requirements of EN14214, a standard for biodiesel quality. The optimization of the biodiesel synthesis process using non-edible hempseed oil contributes to the exploration of alternative and sustainable feedstocks for biodiesel production. The values of the produced biodiesel within the standard range demonstrate its suitability for commercial applications and strengthen the potential of hemp seed oil as a suitable raw material for biodiesel production.

“…Saturated fats are stored in neutral lipid bodies while unsaturated fats are connected with polar lipids in membranes maintaining membrane fluidity under fluctuating cultivation conditions [ 37 , 38 ]. The overall lipid fraction can represent up to 20–50% of the dry biomass, depending on the microalgal species and cultivation conditions such as nutrient availability, salinity, light intensity, and growth phase [ 39 ]. During nutrient depletion, the neutral lipid, and polysaccharide content can increase at the expense of proteins [ 40 ].…”

Over the years, microalgae have been a source of useful compounds mainly used as food and dietary supplements. Recently, microalgae have been used as a source of metabolites that can participate in the synthesis of several nanoparticles through inexpensive and environmentally friendly routes alternative to chemical synthesis. Notably, the occurrence of global health threats focused attention on the microalgae application in the medicinal field. In this review, we report the influence of secondary metabolites from marine and freshwater microalgae and cyanobacteria on the synthesis of nanoparticles that were applied as therapeutics. In addition, the use of isolated compounds on the surface of nanoparticles to combat diseases has also been addressed. Although studies have proven the beneficial effect of high-value bioproducts on microalgae and their potential in medicine, there is still room for understanding their exact role in the human body and translating lab-based research into clinical trials.

“…[118] Esterification reactions normally occur at high temperatures, anywhere from 60 to 80 degrees Celsius, and can be finished in a few hours. [119,120] Both the quantity and quality of biodiesel produced are sensitive to the reaction circumstances, which include factors like the catalyst type and concentration, the alcohol-to-oil ratio, and the reaction temperature. [121,122] Esterification is less common than transesterification, which is a crucial distinction to make.…”

Biodiesel produced from different edible and non‐edible feedstocks is a viable alternative option for fueling a combustion engine. However, the widespread use of edible sources for biodiesel production may lead to food versus fuel controversy. Oil from non‐edible feedstock is best possible solution for problems that inhibits biodiesel production on commercial scale. This study presents the potential of different non‐edible feedstock for biodiesel production. Several aspects such as extraction technologies used for extracting oil from non‐edible sources and biodiesel production pathways from non‐edible feedstocks are discussed. The quality of biodiesel should be assured before its commercialization by different physical and chemical characterization techniques are used. In particular, the emission comparison of biodiesel derived from the different non‐edible feedstocks is discussed. Based on this study, the non‐edible feedstocks have the potential to produce biodiesel but still it has a long way to go. This is due to non‐edible feedstock is in the R&D phase and needs more research to eliminate additional treatment steps compared to edible feedstock for economic aspects. Furthermore, there has been a trade off in emission properties of biodiesels produced from non‐edible feedstocks which must be removed or evaluated for pilot scale investigations before commercialization.
