“…It was also discovered that the waste crab shell catalyst exhibited similar performance to laboratory-grade CaO with a yield of 91.00%, providing an alternative, cost-effective catalyst source for biodiesel production. This aligns with the findings of another study conducted by Karkal et al (2023), where they utilized portunus sanguinolentus crab shells to create a heterogeneous base catalyst for the transesterification of marine fishmeal plant oil. In their study, they achieved a remarkable maximum biodiesel yield of 88.56% under specific conditions, including a 1:9 (mol/mol) oil to methanol molar ratio, a 3.00% concentration of calcined crab shell catalyst (Figure 1), a reaction temperature of 60 °C, and a reaction time of 60 minutes.…”

“…Furthermore, the investigations conducted on the biodiesel produced from waste crab shells in their study confirmed its feasibility based on its physicochemical characteristics. Notably Karkal et al (2023) also reported on the catalyst's reusability, demonstrating its favorable potential for reuse for up to four cycles, with only a minor 10.00% reduction in catalytic activity. This highlights the catalyst's significance in promoting sustainable biodiesel production.…”

The utilization of renewable biomass resources for biofuel production has gained widespread popularity as an effective means of converting waste into a valuable resource. This study investigated the optimization of biodiesel production from coconut oil (CO) using a bifunctional catalyst derived from crab shell and coconut shell. The catalyst underwent characterization through Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction, and Brunauer-Emmett-Teller. The acid precursor for the bio-based bifunctional catalyst was created from carbonized and sulfurized coconut shell, while the base precursor was obtained from calcined and KOH-treated crab shell. The experimental design was optimized using Box-Behnken design for the simultaneous esterification and transesterification of CO. Response surface methodology was employed to model and optimize the process. Under the determined ideal conditions, which included a methanol to oil ratio of 16.75:1, a 1.00% catalyst loading, a temperature of 58.19 °C, and a reaction time of 78.76 minutes, a CO methyl ester yield of 85.73% was achieved under experimental conditions. This yield closely aligned with the predicted range of 85.84% as per the model. The resulting methyl ester (biodiesel) obtained under these optimized conditions exhibited physicochemical properties well within the requirements specified by ASTM D6751 set by the International Organization of Standardization.

“…Biodiesel, composed of fatty acid methyl esters (FAMEs), possesses a multitude of advantages in contrast to conventional diesel fuel. For one, it reduces GHGs emissions and has a lower carbon footprint . It also produces lower levels of toxic pollutants, such as sulfur oxides, benzene, carbon monoxide, carbon dioxide (CO 2 ), nitrogen oxides, and particulate matter …”

A new sustainable solid carbon catalyst has been developed for biodiesel synthesis using pyrolytic coconut shell ash (CSA). The CSA support was loaded with various amounts of potassium carbonate (K2CO3), and response surface methodology with a central composite design was used to optimize the transesterification process. The best-performing catalyst was the 30 wt % K2CO3/CSA catalyst. The optimal conditions included a catalyst loading of 3.27 wt %, methanol:oil molar ratio of 9.98:1, reaction time of 74 min, and temperature of 65 °C, resulting in an obtained biodiesel yield of 97.14%. This catalyst was reusable for up to four cycles, but a reduction in the biodiesel yield was observed due to potassium ion leaching during the recovery process. A techno-economic analysis to assess the financial viability of the project revealed a net present value of 5.16 million USD for a project lifetime of 20 years, a payback period time of 2.49 years, and an internal rate of return of 44.2%. An environmental assessment to evaluate the impact of global warming potential from the production of biodiesel revealed a lower level of carbon dioxide emission (1401.86 ton/y) than in the conventional process (1784.6 ton/y).
