' (117 chars) description => protected'Use of black soldier fly (<em>Hermetia illucens</em> (L.), Diptera: Stratiom
         yidae) larvae (BSFL) is among the solutions being explored to shift the valu
         e chain in organic waste management by producing valuable products. Although
          BSFL consume a range of substrates, nutrient-imbalanced materials with high
          hemicellulose and lignin content, e.g. manure and banana peel, yield low co
         nversion into larval biomass. This study explored pre-treatment methods to i
         mprove the nutrient composition and digestibility of banana peel to achieve
         higher substrate conversion into BSFL biomass. The pre-treatment methods eva
         luated were microbial, chemical (non-protein nitrogen), heat-based, and comb
         inations of these. All pre-treatments tested except heating resulted in more
          efficient BSFL conversion in terms of final larvae weight. The low BSFL res
         ponses in pre-treatments were caused by the observed high amounts of tannins
          and phenolic compounds mainly from the heating pre-treatment. Waste to biom
         ass conversion ratio correlated negatively with substrate volatile solids (V
         
         
         ganisms to achieve maximum degradation of the substrates, facilitating larva
         
         
         L treatment, measured as protein produced per kg incoming material.

' (113 chars) description => protected'Global population growth has led to an urgent need for more efficient food p
         roduction systems. Moreover, as income levels increase, dietary preferences
         are shifting to more animal-based products. However, current feed protein so
         urces deplete wild fish populations and contribute to rainforest deforestati
         on. Capturing the resources in organic waste could help alleviate environmen
         tal impacts of food production. The larvae of the black soldier fly (<em>Her
         metia illucens</em>) are ferocious feeders on decomposing organic material a
         nd could be used as protein source in animal feed. This study evaluated deve
         lopment of black soldier fly larvae on eight urban organic waste fractions a
         nd two control substrates. Principal component analysis was conducted to ide
         ntify substrate properties that contributed to treatment efficiency and larv
         al development. The main treatment factors found to be affected by substrate
          were waste-to-biomass conversion ratio, larval development time and final p
         repupal weight. The substrate properties with the greatest impact on biomass
          conversion ratio and larval development time were content of total volatile
          solids and protein content, while only total volatile solids content affect
         ed final prepupal weight. It was concluded that black soldier fly larvae are
          versatile in their feedstock preferences and can be used to treat a variety
          of organic waste streams, provided that the total volatile solids and nitro
         gen content are sufficiently high to support larval development. Abattoir wa
         ste, food waste, human faeces and a mixture of abattoir waste e fruits &amp;
          vegetables are waste streams that are highly suitable for fly larvae treatm
         ent.
