“…However, there is a large variation in nitrogen contents of excrements within the species as well, and horse manure does not necessarily contain less nitrogen compared to other domestic animals (Moreno-Caselles et al, 2002). Horse manure also has a considerably higher fibre content compared to manures produced by pigs and cattle (Mönch-Tegeder, Lemmer, & Oechsner, 2014), which may have contributed to its poor quality as food for the black soldier fly larvae. Identifying the reasons for the observed lack of suitability require further investigations.…”

Black soldier fly is a common and widely distributed saprophagous species that has an excellent potential for being used for biological conversion of organic wastes on an industrial scale. The main goal of the reported study was expanding the list of wastes suitable for utilization by this species. We compared larval growth on cull potatoes, horse manure and cafeteria food waste in 100‐L bins in a greenhouse. We also conducted laboratory experiments to investigate whether black soldier fly larvae are affected by the presence of moxidectin, a common endectocide used to treat an array of domestic animals and readily excreted in faeces, in their food substrates. Feeding on potatoes resulted in slower growth, and the final size of potato‐fed larvae was smaller compared to the larvae fed on cafeteria waste. Nevertheless, potatoes supported substantial biomass accumulation, and could be a valuable option for rearing fly larvae for commercial feed production. Larvae feeding on horse manure gained very little weight and eventually failed to pupate. Moxidectin had a strong negative effect on larval survivorship; however, ca. 30% of larvae reared in the substrate containing a realistic field concentration of moxidectin still survived to adulthood. Our findings confirm that using black soldier fly larvae is a promising technology for recycling organic wastes, including those of plant origin.

“…In this trial, the treatment time was set to 15 s and the filling of the cross flow grinder finished when the current draw reached 65% of the maximum. This setup was chosen according to Mönch-Tegeder et al (2014b) who achieved the best pretreatment efficiency in his trials. The substrate was supplied to the digester every 120 min.…”

“…In this research, we anticipated that the overall performance of AD could be improved if the hydrolyzing and fermenting process of HM and FW were conducted before methanogenesis within the same anaerobic digester. On the other hand, the transfer and digestion of large fibrous particles in manures are liable to cause technological issues like choking of pumps and pipes 18, 19 . For this reason, only liquid manures are commonly used in practical AD plants while the utilization of most of solid manures or other residues with fibrous materials is limited in conventional AD digesters.…”

A novel compact three-stage anaerobic digester (HM3) was developed to combine the advantages of high solids anaerobic digestion (AD) and wet AD for co-digestion of food waste and horse manure. By having three separate chambers in the three-stage anaerobic digester, three different functional zones were created for high-solids hydrolysis, acidogenesis and wet methanogenesis. The results showed that the functionalized partitioning in HM3 significantly accelerated the solubilization of solid organic matters and the formation of volatile fatty acids, resulting in an increase of 11~23% in methane yield. VS reduction in the HM3 presents the highest rate of 71% compared to the controls. Pyrosequencing analysis indicated that different microbial communities in terms of hydrolyzing bacteria, acidogenic bacteria and methanogenic archaea were selectively enriched in the three separate chambers of the HM3. Moreover, the abundance of the methanogenic archaea was increased by 0.8~1.28 times compared to controls.
