Using readily available biomass, it is possible to produce fatty acid methyl esters (FAME) at a low cost. This study focused on the transesterification process of waste frying vegetable oil to generate FAME (biodiesel) using a cost‐effective heterogeneous nano‐catalyst synthesized from waste cow teeth (CT). The cow teeth nano‐catalyst (CTNC) was synthesized via a three‐step method of calcination, hydration‐dehydration, and re‐calcination. The synthesized CTNC samples were characterized. The Box–Behnken design of response surface methodology (RSM) was used to obtain the optimal operating conditions that maximize the FAME yield (Y 1 ) and the effects of the transesterification process conditions on FAME production. The results revealed that CTNC is of microporous structure with higher crystallinity. It consists of hydroxyapatite, beta‐tricalcium phosphate, and calcium oxide, having a mean particle size of 43.96 nm, a specific surface area of 124.77 m 2 /g, and a pore volume of 0.303 cm 3 /g. The process conditions that significantly influenced the EWFVOME yield were the CTNC loading, reaction time, and MTOR. A maximum of 98.70% (Y 1 ) was obtained at the optimum transesterification process variables of reaction time (2 h), MTOR (12:1), and CTNC loading (3.75 wt%). The biodiesel fuel properties were found to be within the acceptable values of ASTM D6751 and EN 14214 fuel standards.

The transesterification of biodiesel using heterogeneous catalysts has recently caught interest because of its potential to overcome the limitations of homogeneous catalysts. Amongst the heterogeneous catalysts, CaO is well known for its superiority in the transesterification process due to its effectiveness, low cost, and low solubility in methanol. The paper covers the analysis of the transesterification process variables to identify the optimum condition of the process. The effect of process variables, which are catalyst concentration, methanol to oil molar ratio, and reaction temperature, and the interaction between variables on the yield of biodiesel from the esterification of palm oil using CaO catalyst was studied. Response Surface Methodology based on a three-variable central composite design was executed to optimize the process variables. It was found that the concentration of the catalysts is the primary variable affecting the reaction, the molar ratio of methanol to oil is the secondary and the temperature is the ternary. While the interaction between the two variables is not significant in the production of the biodiesel yield. The optimum yield of biodiesel of 98.56% was obtained at a catalyst concentration of 9.63 wt%, methanol to oil ratio of 15.30:1, and reaction temperature of 64.40 °C.

“…Throughout the world, eggshells of chicken, duck, and snails are discarded as waste and their improper disposal leads to environmental pollution that results in various health hazards. Hence, the use of waste eggshells for the generation of nano-CaO as a heterogeneous nano-catalyst is an eco-friendly step [14]. Likewise, edible oil is processed in various food processing units especially in the kitchen and restaurants for frying purposes.…”

This study presents a green process to synthesize biodiesel using biosynthesized nano-catalyst and a novel methodology for analyzing the impact of influencing factors -methanol/oil ratio, the concentration of nano-catalyst, temperature, and time of reactions-on the yield of biodiesel obtained by heterogeneous nano-catalyst-based transesterification reaction. Nano-calcium oxide (nano-CaO) was obtained as a heterogeneous nano-catalyst using waste eggshells. Waste cooking oil was treated with methanol and nano-catalyst at varying methanol: oil ratios (4 -14:1), nano-catalyst concentration (0.5 -2 %), time of reaction (3 -4.5 hrs), and temperature (50 -65 • C). The superiority and effectiveness of the proposed transesterification indices were accomplished making use of Deluca and Termini fuzzy entropy weighted indexes to obtain optimal reaction conditions with 95.49 % biodiesel yield.
