Biodiesel production from the black soldier fly larvae grown on food waste and its fuel property characterization as a potential transportation fuel

Abstract

Insects have a great potential to be used as feedstocks for biodiesel production due to their intrinsic high lipid contents. In particular, biodiesel production from black soldier fly larvae (BSFL) is promising because of its advantages in engineering aspects such as a rapid proliferation, more lipid storage due to long-development time in larva stage, self-separation from organic waste. In this study, biodiesel was synthesized through (trans)esterification of BSFL grown on food waste to achieve both biofuel production from organic waste materials. In addition, all fuel properties of the biodiesel were examined to evaluate its feasibility as a potential transportation fuel in Korea. The highest yield of biodiesel obtained in this study was 86.51%. All the parameters of biodiesel produced from BSFL satisfied the Korea fuel standard (KS M 2965) except oxidation stability. The quality criterion of oxidation stability met the fuel standard with an addition of small quantity of <i>tert</i>-butylhydroquinone.
