Abstract:
The project aims to investigate the potential of using Hermetiaillucens (L.) commonly called as Black Soldier fly larvae (BSFL) to upcycle organic fraction of municipal solid waste (OFMSW) into lipids, protein, and chitin. BSFL have a naturally diverse diet and can decompose biological material and rather low-value waste streams into highly concentrated protein meal and lipids, which are already used worldwide as animal feed. ENORM Biofactory and Aalborg University have been granted permission by the Danish Ministry for Food, Agriculture and Fisheries to conduct controlled trials using biowaste, which is currently not legal as feed in the European Union. Larvae cannot survive in substrates with a water surface on top. To prevent the larvae from drowning, the OFMSW is mixed in varying ratios (0-50%) with proprietary ENORM-feed, consisting mainly of waste streams with a dry matter content of 32%. Continuous measures of larvae growth (body weight, both wet and dry) and substrate humidity were measured during the trial. At the end of the trial, larvae size, survival, substrate composition and dry matter, lipid profile obtained from larvae and chitin content from larvae frass was determined. Samples of larvae and frass were analyzed at Aalborg University for lipidcomposition. The results of this study will provide valuable insights to BSFL composition when fed on OFMSW.
