Summary: This study provides a systematic analysis on material flow and environmental impacts of a food waste bioconversion plant using black soldier fly larvae, identifying significant emissions of methane, nitrous oxide, and ammonia, as well as quantifying their impacts on global warming potential, acidification, terrestrial and marine eutrophication, and particulate matter. Post-composting emissions, energy consumption, and fertilizer substitution ratio are identified as major contributors to these impacts, with mineral fertilizer and protein feed substitution ratio and energy consumption being identified as the most influential parameters. Control of the post-composting process is crucial in reducing environmental load caused by nitrogen-related emissions.

Summary: This study investigated the effects of six different pyrethroid and organophosphate insecticides on the performance of black soldier fly larvae. The results suggest that even exposure to concentrations complying with legal limits can cause significant reductions in yield. Exposure to multiple substances at lower concentrations resulted in negative additive and synergistic effects. It is recommended that rearing companies implement lower contractual thresholds, and that policymakers consider adjusting legally allowed maximum residue levels in insect feed.

Summary: Phosphorous resources are finite, and sewage sludge recyclates (SSR) can be a potential source of minerals in animal nutrition. Black soldier fly larvae (BSFL) can convert low-grade biomass into valuable proteins and lipids, and accumulate minerals in their body. The study found that feeding BSFL with SSR-containing substrates can modify and increase their mineral content, especially calcium and phosphorous.

Summary: Supercritical defatting process was used to extract oil from H. illucens larvae, and the effect of moisture content on oil recovery and composition was analyzed. Results showed that moisture content had no negative impact on oil recovery efficiency, which was mainly determined by the initial oil content. The extracted oil was rich in saturated fatty acids, especially lauric acid, and contained minor lipids such as squalene and phytosterols.

Summary: The commercialization of using black soldier fly larvae (BSFL) as animal feed is limited due to unclear legislative requirements. This paper discusses the legislative landscape in different regions regarding the use of BSFL as feed. The European Union, Australia, Canada, and the USA specifically allow the trade and manufacture of BSFL as feed under specific conditions, while countries with a tradition of entomophagy are currently drafting regulatory frameworks.

Summary: The drying temperature and time of insects affect their crude lipid yield, with higher moisture loss leading to higher lipid yield. Freezing and oven drying larvae results in a high amount of free fatty acids. The Hermetia illucens prepupae contain predominantly saturated fatty acids, followed by monounsaturated fatty acids and polyunsaturated fatty acids, with a substantial amount of lauric acid. The optimal crude lipid yield and moisture loss temperature have been determined.

Summary: Research on Zoophytophagous predators, particularly the mirid Nesidiocoris tenuis, has shown that behavioral observations and mechanical studies are crucial in understanding their feeding activities and damage potential on tomato plants. The study revealed that fifth-instar nymphs of N. tenuis exhibit a higher frequency of probing and spend more time feeding on tomato plants, particularly on cell-rupturing events, compared to adults. These findings suggest that targeting the feeding behavior of fifth-instar nymphs may lead to effective control strategies for minimizing damage caused by N. tenuis on tomato crops.

Summary: This study investigated the competition between housefly larvae and microorganisms for easily digestible carbohydrates, such as starch. The results showed that the highest wet yield and heaviest larvae were observed in sterilized chicken excreta with added starch. Moreover, substrates with added fructo-oligosaccharides had minimal yields and larval weights. The study also found differences in substrate temperature profiles and larval size distributions.

Summary: Due to the growing demand for food, the use of co-products from the food and biofuel industry in livestock feed is expected to increase. However, these co-products, which are fiber-rich, can negatively affect pellet manufacturing, leading to reduced pellet quality and increased energy costs. This study aimed to investigate the impact of including fibrous co-products in feed on their thermomechanical properties and subsequent effects on pellet manufacturing.

Summary: In-home pet food testing provides directly applicable data to the pet population. This study investigated key requirements for an in-home canine food digestibility protocol, using 60 dogs of different breeds and ages. The results showed that one day of faecal collection yielded reliable digestibility values for all nutrients, and the minimal required sample size ranged from 9 to 43 dogs depending on the accepted margin of error.

Summary: In-home cat food digestibility testing has the potential to provide representative data, but there are currently no standardized protocols available. This study investigated key factors affecting variation in cat food digestibility, including adaptation period, fecal collection, and sample size. The findings suggest that a minimum of 2 adaptation days and 3 fecal collection days are needed for future in-home digestibility tests.

Summary: The aim of this study was to compare the digestion and physiological effects of isomaltulose with other saccharides in dogs. The results showed that isomaltulose had a slower digestion and lower blood glucose response compared to sucrose. However, sucrose had a higher blood glucose response, suggesting the presence of an adaptive response. Therefore, further research on the digestion physiology of saccharides in dogs is warranted.

Summary: Shear cell technology is a promising method for meat analogue production. This study investigated the effect of shearing and sterilization on the amino acids and oxidation markers in soy protein- and pea protein-based meat analogues. The results showed that processing led to modified amino acids and more pronounced oxidation in the pea-based analogue. Despite extensive thermal treatment, the impact on protein quality in plant-based products was comparable or less than that in animal-based pet food.

Summary: Overweight and obesity are common in pet cat populations worldwide. Understanding how properties of food affect appetite is crucial. This study used a model of operant conditioning to assess the effects of protein, fiber, and meat preparation on cat appetite. The findings suggest that dietary protein and fiber levels, as well as meat grinding and cooking, influence cat appetite.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
