“…Whole insects and meal could satisfy the demands of the food processing industry, while protein bars would increase the demand of those consumers who engage in sports regularly or follow balanced diets, ensuring a diversification of available proteins at markets due to their origin and to their environmental impact. In fact, despite recent studies highlighting that the environmental impact of insects bred for feed use is not low (Bosh et al, 2019;Smetana et al, 2019), the use of different rearing substrates, from a circular economy point of view (Le Féon et al, 2019), could make this production environmentally sustainable.…”

In recent years, there has been a growing interest in the novel food market due to the growing demand for protein-rich food and the diversification of the protein sources currently used. The edible insect and insect based-food sector has recently experienced an increase in the quantities produced and traded. This increase has occurred thanks to awareness-raising actions and the development of European regulations. The limited development of this sector does not permit in-depth market and business analyses, since it is still in formation, which means that it is still a relatively unexplored field of study, especially on the European scene. The objective of this study is to carry out a preliminary investigation of the consistency, typology and product assortment of the companies located in the European Union and which are focused on the production and marketing of insect-based products. The survey was performed through the investigation of the E-commerce catalogues and Internet websites of the companies. The study also focuses on the main insect species used, the origin of the raw material used and the prices of products currently available on the European market. The results show that companies are mainly located in the northern European countries and that the most used distribution channels are the E-commerce websites, compared to physical retail outlets. Most companies also buy their raw material from third party companies, even non-European ones, and then process or only resell the product. The products which sold the most were whole insects or insect meal, mainly based on Tenebrio molitor or Acheta domesticus. Prices showed a high variability, in particular related to the species used and how it is packaged.

“…A life cycle assessment study indicated that insect proteins present lower environmental impacts than fishmeal over most of the impact criteria [11]. Although, such beneficial features are strongly conditioned by the type of agricultural co-products and waste-streams used as nutritional substrates to grow the insects [12,13]. Given these promising features of IM, several types of insects, such as locusts, grasshoppers, termites, yellow mealworms, Asiatic rhinoceros beetles, superworms, domesticated silkworms, common houseflies, common mosquitoes, and black soldier flies have been evaluated for inclusion in aquafeeds [2].…”

Insects are emerging as a sustainable alternative to fishmeal and fish oil in aquafeeds. This study assessed the effect of graded incorporation levels of defatted yellow mealworm (Tenebrio molitor) protein meal on juvenile rainbow trout (Oncorhynchus mykiss) growth performance, body composition, and apparent nutrient digestibility. The trial comprised five dietary treatments: control diet with 25% fishmeal, and four experimental diets with yellow mealworm protein meal at 5%, 7.5%, 15%, or 25%, which corresponded to a fishmeal replacement of 20%, 30%, 60%, or 100%, respectively. After 90 days, the graded incorporation of insect protein meal led to a significant stepwise increase in final body weight, and a significant improvement of specific growth rate, feed conversion ratio, and protein efficiency ratio compared to the control treatment. Regardless of the incorporation level, the insect protein meal had no effects on fish whole-body composition and apparent digestibility coefficients of dry matter, protein, fat, phosphorus, and energy. Protein, phosphorus, and energy retention significantly increased in fish fed the diets with an insect protein meal. In conclusion, the yellow mealworm protein meal could effectively replace 100% of fishmeal in the diet of juvenile rainbow trout with positive effects on its overall zootechnical performance.

“…Neither types of cricket species that are the subject of this study (G. bimaculatus nor G. sigillatus) are native to the UK: they are commonly found in the tropics and sub-tropics (Eades et al 2018;Roskov et al 2018). The farm has found that they thrive best at a temperature of approximately 30°C.…”

Purpose Rearing crickets in the UK for the live pet food market is already a well-established industry. However, there is interest in also producing food for human consumption. This paper presents a life cycle assessment (LCA) of a current live pet food business. Using results from this LCA, the papers explores how current business practices could be improved to reduce environmental impacts, and discusses the potential benefits of a hybrid live pet food/human consumption business model. Methods An attributional, cradle-to-farm-gate life cycle assessment was conducted on rearing crickets for the live pet food market, with data collected on-site at a case study business. Results are reported in multiple impact categories from the ILCD 2011 Midpoint+ method. Comparison is made to the only other similar study: an LCA of rearing crickets in Thailand for human consumption (Halloran et al. J Clean Prod 156:83-94, 2017). The sources of the different environmental impacts between the two studies are explored and inefficiencies in the live pet food rearing process identified. Subsequently, scenarios are used to explore how the inefficiencies may be mitigated, and environmental impact of the live pet food production process reduced through adoption of a hybrid live pet food/human food production model. Results and discussions The environmental impact was found to be larger across all impact categories than the only known comparable study, which is for rearing crickets in Thailand for human consumption (Halloran et al. J Clean Prod 156:83-94, 2017). Some of this difference is due to the heating required for rearing crickets in a climate such as the UK, and some is due to the requirements of the live pet food market being much more demanding on resources than the human food model. The current study identifies improvements in practices that would make this contrast less stark, such as optimizing feeding practices, and the benefits of moving to a hybrid live pet food/human consumption business model. Conclusions This is the first LCA of crickets reared in the UK. The results highlight inefficiencies in the rearing process that are now being addressed by the case study business. The study also shows the potential co-benefits of a hybrid business model, in which crickets for human consumption are produced alongside crickets for the live pet food market.
