Making Methyl Esters of Fatty Acids from Black Soldier Flying Flies through the Reaction in Situ Transesterification Using Controlled Destroyers

Introduction

The world is facing a significant challenge in finding alternative and sustainable sources of energy to reduce our reliance on fossil fuels. One promising solution is the production of biodiesel from organic waste, such as the larvae of the black soldier fly (BSF). In this study, we explored the process of making methyl esters of fatty acids, or biodiesel, from BSF larvae through the transesterification reaction in situ. The variables tested included the catalyst concentration, reaction time, the weight ratio of BSF larvae to methanol, and the speed of stirring using controlled destroyers.

The Transesterification Reaction

The transesterification reaction is a chemical process that involves the conversion of vegetable oils or animal fats into methyl esters of fatty acids, which are the main components of biodiesel. This process is accelerated by a catalyst, such as sodium hydroxide (NaOH), and involves the reaction of the oil with methanol. The reaction conditions used in this study were variations in the concentration of NaOH solution in methanol, which ranged from 0.5% to 12%. The reaction time tested ranged from 10 to 90 minutes, with the weight ratio of BSF larvae to methanol varying between 1:1 and 1:5. The stirring speed also varied between 3000 and 8000 rpm.

Measurement of Conversion and Functional Groups

The conversion of methyl ester fatty acids was measured using gas chromatography (GC), while changes in functional groups from oil to methyl esters of fatty acids were determined through the FT-IR spectrophotometry. The results showed that the highest conversion of methyl esters of fatty acids reached 93.8 ± 0.0% under the reaction conditions with a catalyst concentration of 7%, reaction time of 20 minutes, BSF ratio to methanol 1:2, and stirring speed of 3000 rpm.

Additional Analysis and Explanation

Making biodiesel from BSF larvae is a promising solution in the use of organic waste, because this larvae can convert organic matter into a sustainable source of energy. BSF larvae are rich in fat, which functions as the main raw material in biodiesel production. The transesterification process carried out in this study utilizes chemical reactions involving vegetable oils or animal fats and alcohol (methanol) which are accelerated by the catalyst (NaOH).

With variable control such as catalyst concentration and reaction time, this study has reached a very high conversion, which is 93.8%. This shows that the right reaction conditions greatly affect the efficiency of the process. This study also emphasizes the importance of the ratio between BSF larvae and methanol, where the 1:2 ratio is proven to provide optimal results.

Identification of Methyl Esters of Fatty Acid Methyl Esters

Identification of methyl esters of fatty acid methyl esters is carried out with FT-IR spectrophotometry, which shows a significant difference at the peak of -C-O-C- in the wave range of 1300-1000 cm-1. In oil, the peak of the strongest absorption is in the middle position, while in the methyl ester fatty acids from BSF larvae, the strongest peak appears in a further position, which indicates changes in the chemical structure during the transesterification process.

Conclusion

The results of this study provide evidence that the larvae of black soldier flies can be a valuable source for biodiesel production through an efficient process. With good parameter control, fat conversion into methyl esters of fatty acids can be optimized, giving hopes for the use of more sustainable biological resources in the energy industry. This not only opens opportunities for biodiesel production, but also provides additional benefits in managing organic waste.

Future Directions

This study has shown the potential of using BSF larvae as a source of biodiesel production. However, further research is needed to optimize the process and to scale up the production. Additionally, the economic viability of this process needs to be evaluated to determine its feasibility for commercial production.

Recommendations

Based on the results of this study, the following recommendations are made:

  • Further research is needed to optimize the process and to scale up the production.
  • The economic viability of this process needs to be evaluated to determine its feasibility for commercial production.
  • The use of BSF larvae as a source of biodiesel production should be encouraged and supported.

Limitations

This study has some limitations that need to be addressed in future research. These include:

  • The use of a single type of catalyst (NaOH) and the need to explore other catalysts that may be more efficient.
  • The limited range of reaction conditions tested and the need to explore a wider range of conditions.
  • The need to evaluate the economic viability of this process.

Conclusion

In conclusion, this study has shown the potential of using BSF larvae as a source of biodiesel production through the transesterification reaction in situ. With good parameter control, fat conversion into methyl esters of fatty acids can be optimized, giving hopes for the use of more sustainable biological resources in the energy industry. This not only opens opportunities for biodiesel production, but also provides additional benefits in managing organic waste.
