Summary The present research develops an innovative nutrient recovery strategy for capturing of un‐utilised nutrients from agri‐food byproducts using a combination of solid state fermentation ( SSF ) and insect rearing. SSF of borage and flaxseed meals were performed using GRAS organisms to release indigenous nutrients and to produce additional nutrients. Proximate analysis of the SSF ‐meals showed increases in both lipid and protein contents. Black soldier fly larvae ( BSFL ) were then grown on these SSF ‐meals for 12 day. The meals fermented singularly with Lactobacillus plantarum or Aspergillus niger displayed up to 30% enhancement in BSFL biomass, and dual fermentation with L. plantarum and Aspergillus oryzae resulted in an additional 10% enhancement. These examinations showed SFL use over‐90% of proteins and lipids in SSF ‐meals. The results indicate that fermentation of these low‐value meals can boost the efficacy of larval growth and the recovery of nutrients from agricultural byproducts as larval biomass.
