“…The most considered barrier to the addition of insects in animal diets is general acceptance. The food preference of consumers is not only based on palatability, nutritional content, and environmental gain, but it is also affected by emotional and cultural factors such as experience, cultural associations, and adaptations [78]. BSFL as protein is achieving fast recognition as a high-value protein component in the diets of animals, especially pets and aquaculture [79].…”

The increasing global population poses a problem in achieving food security. Poultry is one of the major animal protein sources for humans and the main difficulty of the poultry industry is seeking a suitable protein alternative to be integrated into poultry feed. Black soldier fly larvae (BSF) (Hermetia illucens) are one of the edible insects that are a great solution to this problem since they have various advantages, which include bioconversion of different organic wastes and the absence of competition for human resources. Several studies have already examined the effects of the addition of BSF larvae in the poultry diet, and most suggested that it is a promising alternative protein source that can replace soy or fish meal. The BSF larvae can also be used in different species of poultry, such as ducks, turkeys, and quails. However, there are several barriers to using BSF larvae as a feed ingredient in poultry feed, such as safety, price, and consumer acceptance. Despite these obstacles, BSF larvae production is still a promising industry due to the numerous benefits it brings.

“…The process would generate BSFL to be used as animal feed and the residue to be used as a soil conditioner and plant nutrient. Walter et al [43] demonstrates that utilises food manufacturing waste as a feedstock for BSFL production, as shown in Figure 3. This approach is tested using food waste data collected from 38 UK-based food manufacturers, as shown in the Supplementary Materials.…”

Processes that utilise low-value wastes and convert them to high-value food ingredients systemically add value across commercial operations. Current common disposal options include use as animal feed, anaerobic digestion, composting, incineration, and the worst-case options of landfill and wastewater disposal. The pressure is acute with food manufacturers needing to align with the UN Sustainable Development Goals and reach targets of zero waste to landfill. This research identifies black soldier fly larvae as a bioreactor that converts most food waste into high-value feed materials. Production of larvae and the regulatory framework for their use as animal feed is being assessed in several nations. The requirement to understand the availability of feedstocks for larvae production and the capability to establish feedstock supply chains was tested in this study using geographical information system and life cycle assessment methodologies, providing new research insights for resource utilisation in a circular economy.

“…Compared to traditional livestock, it requires less land and water, yet achieves higher reproduction and conversion rates while generating lower greenhouse gas emissions (van Huis and Oonincx, 2017). Furthermore, it could play a pivotal role in promoting a circular economy by transforming organic waste (e.g., food wastes and manure) into valuable protein and fat, thereby minimizing resource consumption and establishing an efficient loop within the food and feed production system (Cadinu et al, 2020; Walter et al, 2020). Among the vast range of edible insects (Jongema, 2017), species such as the black soldier fly (BSF; Hermetia illucens , Linnaeus 1758), the yellow mealworm (YMW; Tenebrio molitor ; Linnaeus, 1758), and Jamaican field cricket (JFC; Gryllus assimilis ; Fabricius, 1775) have become popular among insect farmers in Western countries (Wilkie, 2018).…”

Frass fertilizers from mass-reared insects: species variation, heat treatment effects, and implications for soil application

Insect farming has gained popularity as a resource-efficient and eco-friendly method of managing organic wastes by converting them into high-quality protein, fat, and frass. Insect frass is a powerful organic fertilizer, enriching the soil with essential plant nutrients and enhancing plant defense mechanisms through chitin stimulation. Given the importance of frass commercialization for many insect farmers and the use of increasingly diverse organic wastes as insect feedstock, the need for legal guidelines to enable clean production practices has emerged. The recent introduction of a legal definition for frass and heat treatment requirements by the EU commission marks a significant step towards standardizing its quality. However, frass composition is influenced by numerous factors, and little is known about the processes shaping its nutritional profiles and contributing to its maturation. Here, we analyzed the physicochemical, plant-nutritional, and microbiological properties of black soldier fly, yellow mealworm, and Jamaican field cricket frass from mass-rearing operations and assessed the impact of hygienizing heat treatment. Frass properties varied significantly across insect species, revealing concentrations of plant available nutrients reaching as high as 7000 μg NH4+, 150 μg NO2-NO3--N, and 20 mg P per g of total solids. Heat treatment affected microbial activity by reducing basal respiration and microbial biomass carbon, but also reducing viable counts of pathogenicE. coliandSalmonella sp.In terms of microbiome composition, alpha diversity showed no significant differences between fresh and heat-treated frass samples within each insect species, but significant distinctions were observed across the three insect species. The soil application of frass reactivated and boosted soil microbial activity, suggesting no long-term detrimental effects on microorganisms. These results further highlight the potential of insect frass as nutrient rich organic fertilizer, with promising benefits for soil health and nutrient cycling.
