Bioconversion by Hermetia illucens larvae is a novel technology for organic waste treatment and valorization. However, since the possible uses of products from this process are in agriculture and livestock, the bioconversion must guarantee the mineral quality of both the Hermetia illucens larvae frass and larval biomass. Therefore, this study aimed to assess the mineral content changes for both the larval biomass and larvae frass of Hermetia illucens after the manure bioconversion to determine their suitability as animal feed and organic fertilizer, respectively. Hermetia illucens larvae were put into a plastic box containing fresh cattle manure, and the control treatment with the same conditions without larvae was established. After the first pre-pupae were detected, frass and larvae were collected, and their mineral content was analyzed. At the end of the experiment, the larvae showed increases in some micro and macronutrients, especially calcium and manganese, increasing up to 2.6 and 22.6 times the initial concentration, respectively. The toxic elements concentration was increased in larval biomass, but these levels met the international legislation for animal feed. As a result, the mineral content in larval biomass revealed that Hermetia illucens could be potentially used as animal feed, which could be comparable with fish meal, and is probably better than soybean meal. However, the larvae frass could only be used as organic fertilizer in a Canadian context, with further treatment for decreasing the chromium content being necessary.

“…For example, when employing non-catalytic transesterification to extract BSF larval lipids, Jung et al (2022) obtained 94.1 wt% biodiesel, and the fuel characteristics of BSF larvae were in line with Korea and EU biodiesel fuel specifications. Through Hermetia illucens larvae, Matos et al (2021) found that methane emissions from the bioconversion of animal dung were 86% lower than those from controls. Fig.…”

Black soldier fly (BSF) studies have attracted increasing scientific attention because of their role in determining sustainability. However, there exists rare quantitative analyses of the scientific literature on research of BSF, especially for visual analyzing from the systematical and bibliometric perspective has not been reported. Therefore, the investigation on the temporal development, scientific collaboration, research hotspots and frontiers in terms of BSF over the last 28 years (1994-2021) is executed for the first time. Combined with the Web of Science Core Collection database, this study collected 914 literatures from 1994 to 2021 that were conducted co-occurrence, co-citation and cluster analysis via CiteSpace software. The main findings are as follows: Firstly, research on BSF has advanced rapidly during the recent five years and Italy, USA and China were the three core force leaders countries with the high publications, centrality and cooperation degrees. In addition, Huazhong Agr Univ showed the core force ranked the third in the world of BSF research, which had high publications and strong cooperation with international institutions. Furthermore, in terms of keyword co-occurrence, time-zone and burst analysis delineated biological characteristics, application and management of BSF larvae were the main research themes. And early studies concentrated on BSF development and breeding, and current hotspots include exploiting BSF larvae as animal feed and recycling organic wastes. Additionally, based on co-cited references cluster analysis, it was concluded that the bioconversion and animal feed using the BSF larvae will still be the focus research fields in the near future, and the technical improvement on the efficiency of bioconversion, integrating the healthy, safety and eco-friendly that future studies should focus on, supporting policy making that indicate the prospective research field on BSF and it’s applications.

“…In the meantime, the remaining slurry and residue solid are returned to agriculture as fertilizer. Not only the anaerobic fermentation but also the black soldier y (Hermetia illucens) larvae (BSFL) are utilized to digest cattle dung in some studies [6] [7] . After the cattle dung is treated by BSFL, the larvae can be apply in protein generation [8] , and the residue matters are collectively referred to as the frass.…”

Taiwan generates 4,800 tons of cow dung daily, necessitating the development of a novel circular utilization process to increase the recycling value of cow dung. The black soldier fly larvae (BSFL) treatment can digest the cow dung, and the frass (larvae drops) is the residue fibers in cow dung The study aims to assess the feasibility of utilizing the frass in pulp and papermaking by analyzing frass chemical composition, appearance, fiber morphology, and estimating its suitability for soda pulping, with the goal of developing value-added circular utilization process for frass. The chemical composition of the frass shows the high content of holocellulose, α-cellulose and the lower content of ash, which indicates the potential of pulping application. The fiber structure and mesoporous pores of the crude fibers in frass are beneficial for the pulping reaction. The fiber morphology of the frass is similar to non-wood fibers (pulping raw materials), which indicates the feasibility of fiber application. After the soda pulping experiment, pulping the frass with 7% NaOH for 75 minutes results in efficient fiber disintegration with a lesser degradation, which is the highest accepts ratio in the study. The NaOH cause the better disintegration of fibers and the better formation structure of the handsheet. The frass pulp blended with TOCC can enhance the ring crush index and bulk of handsheet. In the meantime, the mixed pulp (frass-TOCC) can achieve the ring crush index and bulk standards required for cardboard, without the chemical additives. To sum up, the fiber-like frass from BSFL treatment of cattle dung can be utilized in pulp and papermaking to enhance circular utilization value.
