“…To varying degrees, application of HF to seedlings as a top-dressing increased shoot dry weight of seedlings in an organically-rich compost based growing medium, and two potting mixes based on garden soil, bark chips, and coir fibre. These results reinforce findings of other studies that similarly demonstrated increases in plant growth in response to application of BSFF-based fertilizers [8][9][10]12]. HF also produced similar increases in shoot growth to two other standard fertilizers, chicken manure pellets and a commercial organic fertilizer [9,13].…”

“…In our experimental system, highest shoot and root growth of test plants occurred when HF was applied at over 4 g, but less than 8 g, per pot, in the region of 1-2% soil volume. Other studies using lettuce and pak choi [10,12] have also reported stunting effects on plant growth when BSFF was applied at high volumes. However, these previous studies applied BSFF at rates in the region of 30-50% soil volume, far higher than the maximum rate of HF used in our study (8 g HF ≈ 2% total soil volume).…”

“…As a by-product, the BSF frass (BSFF) consists of a mixture of leftover feed material, insect skins and faeces, and microorganisms [7,8]. In recent years, there have been a number of studies exploring the potential of frass as a fertilizer, and several reports of how BSFF can have positive effects on plant growth, yield, soil structure and the soil microbiome [8][9][10][11][12][13]. BSFF may also provide additional benefits such as increasing soil organic matter and supplying micronutrients such as copper and zinc, that are essential for plant growth and development [8,13].…”

“…For example, variability in the effects of BSFF on plant performance can occur due to differences in the larval diet [11] and variation in climatic conditions [14]. Other studies have indicated there may be an "optimum" soil concentration of BSFF, and that once this concentration is exceeded plant growth may be inhibited [10,12]. This variability indicates that the results obtained from different sources of BSFF, and results obtained under different environmental conditions, may not be directly transferrable to new products or different growing situations.…”

The mass farming of the black soldier fly (BSF; Hermetia illucens L.), to produce insect-based feed for livestock and fish, results in considerable amounts of insect frass, which contains substantial amounts of organic matter and bioavailable nutrients. Insect frass has shown good potential as a soil amendment and organic fertilizer. This study examined the effects of HexaFrass™ on the growth of common vegetables and herbs under glasshouse conditions. In an organically-rich potting mix, HexaFrass™ increased shoot dry weight by an average of 25%, although this effect was variable among test plants. In other trials, application of HexaFrass™ caused an increase in plant growth similar to that obtained by applying chicken manure and a commercial organic fertilizer. Increases in shoot and root dry weight showed quadratic relationships with HexaFrass™ dose, indicating that application of excessive quantities could lead to plant inhibition. Shoot:root dry matter ratio tended to increase with HexaFrass™ dose suggesting there was no specific stimulation or enhancement of root growth. Overall, these results provide further evidence of the potential of insect frass as an effective organic fertilizer for vegetables and herbs.

Black soldier fly larva (BSFL) or also known as Hermetia illucens is a type of insect that has been studied for its potential to bio convert waste into a form of protein and lipid. As the bio-conversion process of food wastage into profitable sources is robust, environmentally friendly without the need for their end-product to be managed, it is a very promising sustainable method that should be explored more. A small-scale experiment was conducted to gain firsthand experience of the BSF rearing process. A portable BSFL production system was designed, developed, and tested in this study. As an addition to the experience, an experiment on the effect of different types of diet on the development of the larvae to prepupae was conducted and several characteristics of the harvested BSFL also was recorded and compared. Results show that the system can support the rearing of BSF and the different diet consumption affected the larvae size and weight. In conclusion, the system could be employed for the small scale BSFL production that not just helping in taking care of the Malaysian food waste but they will also serve as an awareness-raising measure for circular economic solutions.
