Energy applications

• Oils coming from insects for biofuels was considered (Berezina, 2017)
• Compared (algal, plant such as canola, palm, and insect…)
• “insect” source was much less time consuming
• 2–3 months of growth before being processing
• Comparing to the plant source
• Much less space consuming
• Comparing to the algal source
• Quality of the obtained biodiesel was studied (Zheng et al., 2013)
• Cetane number, the main intrinsic characteristic of the biofuel
• Compliant with the requirements of the European norm EN 14214
• Was 53 for Hermetia illucens
• 58 for Tenebrio molitor
• Much higher than what was observed for canola oil, 45
• Transesterification process to convert the triglycerides in the Tenebrio molitor oil
• Into biodiesel was effective using a conventional base catalyst and resulting in 96.98% (Fatty acid methyl esters (FAME) (Siow et al., 2021)
• Quality of fuel met the requirement of ASTM D6751 biodiesel specification.
• Tenebrio molitor oil
• Is feasible to be an alternative feedstock of third-generation biodiesel
• New technical routes are possible
• Oil extracted from Tenebrio molitor larvae was easily converted to biodiesel by a thermal non-catalytic reaction
• Achieving a 87.75% yield (Lee et al., 2022).
