The use of nano calcium oxide as a catalyst in biodiesel production has gained attention due to its high catalytic activity, low cost, and environmental friendliness. It efficiently converts triglycerides to fatty acids and methyl esters. In the present study, nano CaO was prepared by precipitation and characterized by various techniques. The results showed that the nano CaO has high purity, nanoscale crystal size, good thermal stability, and high specific surface area. Biodiesel was produced by transesterification from waste cooking oil, methanol, and the nano catalyst. Response surface methodology was applied to predict the optimum parameters for the production of the biodiesel based on its yield. The produced biodiesel was characterized by FTIR spectroscopy and GC‐MS and evaluated according to ASTM D6571.

“…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.

“…31 In addition, the formation of abundant glycerin suggested the hydrolysis of the triglycerides in the oil. 32,33 In comparison, the decreases in the production of the nitrogen-containing organics indicated that lard was not conducive to the removal of nitrogen from cabbage (Table 1). Apparently, for the HTC of rice, the addition of lard and rapeseed oil produced more macromolecular fatty acids, which inhibited the production of pentanoic acid, 4-oxo-and promoted the production of small-molecule acids like acetic acid.…”

The fatty esters in cooking oil may not be inert organics. Their potential involvement in hydrothermal carbonization (HTC) of food waste was investigated in this study. Cooked cabbage (vegetable) and rice (staple food) were selected as the feedstock and their HTC in the presence of (vegetable oil) and lard (animal fat) was conducted at 260 °C for 10 h. The results indicated that presence of the cooking oil increased the hydrochar yield (i.e., 71.5% increase for HTC of rice with lard) originating from the reactions between the oil-derived fatty acids and the food-derived alcohols, amines, etc. This significantly increased both the carbon and hydrogen contents and simultaneously reduced the oxygen content of the hydrochar. The additional aliphatics from the cooking oil formed on hydrochar remarkably reduced the thermal stability of the hydrochar, but increased the volatility and led to improved combustion performance through lowering the activation energy for combustion.
