الملخص

This study aims to explore local resources as an entry point for the shift toward alternative energy use, by producing biofuel (biodiesel) using simple and low-cost processing techniques. The experiment was conducted on three different species of algae: Ulva, Cystoseira, and Jania, collected from the coast of the Gulf of Sirte.

The study focused on evaluating the effect of different drying techniques on the efficiency of extracting raw materials and oils from the algae, using three methods: electrical dryer drying, sun drying, and oven drying. Experimental results showed that electrical dryer drying yielded the highest oil extraction rates for the three species, with the red alga Jania recording the highest amount of oil extracted, at 53.0 ml per 10 g of algae dried using this method.

The analyses indicated that samples dried using a electrical dryer achieved the best oil extraction efficiency, followed by oven drying. Sun drying, however, was the least efficient, with a clear variation observed in the quantities of oils and raw materials extracted during processing. These results demonstrate the direct impact of the drying method on the efficiency of extracting organic oils from different algae species. Statistical analyses confirm the validity of these differences, underscoring the importance of choosing the appropriate method in bioprocessing to obtain the best yield from bio-oils.

These results are consistent with several previous studies, which are important for addressing challenges related to biodiesel production efficiency. They also contribute to enhancing the ability to assess local energy resources and support the drive to improve bioprocessing technologies. This project serves as a solid scientific foundation for developing future biodiesel products based on locally available natural resources.
