Summary: Product service systems (PSS) are gaining attention for their potential in achieving a circular economy, yet there is a lack of effective evaluation methods. This study combines life cycle assessment (LCA) and a consumer survey to quantify the environmental consequences of PSS, using the example of digital camera rental services in Japan. Results showed that the rental scenario increased greenhouse gas emissions but also reduced abiotic depletion potential compared to conventional purchase. The study highlights the importance of carefully designing PSS to mitigate unintended consequences.

Summary: The EU energy sector is expected to transition to renewable sources, and a prospective assessment framework has been designed to evaluate the environmental impact of a new biowaste-based energy technology. The framework includes a dynamic input-output model to simulate the implementation of the technology over time and calculates the total impacts on various environmental factors. The simulation shows that the technology can significantly reduce carbon emissions and bring changes to the economy structure. The factors affecting the model output, uncertainties, and assumptions are discussed to assess the framework's scope and limitations for decision-making.

Summary: Rice is a crucial crop in terms of human consumption, and assessing the sustainability of its production process is of great importance. This research investigates the recent literature on Life Cycle Assessment (LCA) of rice primary production to determine the extent to which Life Cycle Thinking (LCT) and sustainability have been applied in the rice sector, as well as identify research gaps. The study reveals limited consideration of multiple functional units, methodological differences leading to result variability, and inadequate focus on socio-economic aspects.

Summary: This paper investigates how the environmental impact of clinker production might change in the future using a consequential ex-ante life cycle assessment. Results suggest that the environmental impact could be reduced by a factor of five with the introduction of carbon capture and electrification of kilns. The sensitivity of clinker production's environmental impact to evolutions in the electricity sector is also highlighted.

Summary: Water use in buildings constitutes a significant portion of global freshwater consumption, but research on the life cycle impacts of water use has been neglected. This study quantified the environmental impacts of operational water use in a multi-family residential building through a life cycle assessment. The results showed higher impacts in the water-stressed country of Qatar compared to Miami, primarily due to the energy-intensive thermal desalination process. This initial LCA analysis is valuable for establishing sustainable water use policies in specific regions and benefiting the overall building environment.

Summary: The study focuses on the environmental impacts of sea lice issues in Norwegian salmon farming, examining different treatment methods, the footprint of cleaner fish value chains, and the contribution of biological lice treatments to the salmon footprint. The research found that wrasse fishing has lower impacts compared to farmed lumpfish and wrasse, but ecosystem impacts and cleaner fish delousing efficiencies need further investigation for a comprehensive comparison. Overall, biological lice treatments are found to have a low contribution to the environmental footprint of salmon production, suggesting that it could be a viable option for sustainable salmon treatment, contingent on confirming treatment efficiency, accounting for ecosystem impacts, and addressing cleaner fish welfare issues.

Summary: This study proposes a novel method for constructing consequential life cycle inventory (LCI) databases based on the heuristic approach by Bo Weidema. The method is tested on the future electricity sector using projections from two integrated assessment models (IMAGE and REMIND). Results show that the choice of modeling technique in each step has a significant impact on the results, especially the selection of the time interval. Additionally, there is a noticeable difference between the projections of the two models. The relevance and goals of alternative techniques for each step are discussed to guide users in forming their own heuristic method.

Summary: PLA is a compostable bio-based plastic suitable for food packaging, with potential for increased organic waste management. Although PLA production has higher impacts compared to petrochemical plastics, diverting PLA-packaged food waste to organic recycling can improve the overall environmental performance. Future diversion of organic waste streams to insect feed could lead to the best environmental outcomes.

Summary: The aquaculture sector is essential in global fish production to meet the increasing demand for high-quality food, but alternative sources to fishmeal are needed due to sustainability concerns. Rapeseed proteins have been recognized as valuable substitutes for fishmeal in aqua feeds, with a balanced amino acid composition and cost-effective cultivation. Further research is needed to fully understand the benefits and effectiveness of rapeseed proteins in aqua feeds.

Summary: Sustainable aqua feeds are essential for the future development of the aquaculture sector, especially considering limited mineral supply from animal-based sources. This study evaluated the effects of chromium DL-methionine supplementation in the nutrition of African catfish. The results showed that supplementation with 0.2 mg Cr kg(-1) and 0.4 mg Cr kg(-1) significantly increased the specific growth rate of the fish, suggesting that organic chromium supplementation is a viable and safe way to improve the growth performance of African catfish.

In this study, the use of carbohydrate and lipid in fish diets was investigated under various thermal regimes. The results showed that diets with carbohydrate as the main energy substrate had higher specific dynamic action values at temperatures around the optimum, indicating the nutritional value of carbohydrates, especially at lower temperatures.

Summary: Ozone produced oxidants (OPO) are secondary oxidants formed during the disinfection process in recirculating aquaculture systems. This study investigates the impact of OPO on juvenile tilapia and finds that adverse effects are observed at a concentration as low as 0.05 mg/L, with severe impact recorded at 0.1 mg/L chlorine equivalents. Therefore, it is important to keep OPO concentrations below 0.05 mg/L chlorine equivalents to avoid adverse effects on animal welfare.

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.
