摘要：In modern agricultural biogas plants, the biowaste are increasingly used for biogas production.Food waste are also widely used in larvae breeding.This is important because, based on biowaste, its proper management and green energy production is possible.This study aims to determine the biogas and methane efficiency of Hermetia illucens larvae that were fed using food waste.In the research on biogas and methane efficiency, Hermetia illucens larvae were used.The total solids (TS) of the substrate equals 30.35%, and volatile solids (VS) content was 92.31% of TS.The larvae were fed only by plant origin food waste.The obtained substrates were homogeneous.The experiment was carried out under mesophilic anaerobic digestion conditions – 39°C in the 21-chamber biofermentor set in the Institute of Biosystems Engineering in Poznań University of Life Sciences.The anaerobic digestion process in the batch reactor ran correctly.Fermentation inhibition was not detected.Biogas efficiency for larvae amounted to 198.75 m3∙Mg-1 fresh mass (FM).On the other hand, methane efficiency, amounted to 127.73 m3∙Mg-1, at methane concentration of 64.27%.Based on the research, it was found that the larvae feeding food waste can be used directly as anaerobic digestion in the bioconversion process.
