Summary: This paper examines the sustainable exploration of building systems by combining ecological concepts and low-carbon designs for a comprehensive sustainability assessment. It utilizes the Life Cycle Assessment (LCA)-Emergy and Life Cycle Assessment (LCA)-Carbon emission methods to discuss various topics, such as contributing factors, sustainability index verification, sensitivity analysis, and potential improvement measures. The findings reveal that the building operation stage plays a crucial role in both emergy and carbon emissions, indicating the need for renewable energy and carbon sink improvement to enhance ecological sustainability and achieve low-carbon designs.

Summary: This study proposes a new water ecology emergy (WEE) analytic system to evaluate the health level of the water ecosystem. By quantifying the ecological-economic flow and converting it to emergy, a set of health diagnosis indicators is proposed and a comprehensive diagnosis method is applied. Using Luoyang as an example, the results show a decreasing trend in the health level of the system in the initial stage, followed by fluctuation and increase in the later stage, mainly due to the improvement in the ecological-environmental benefit ratio.

Summary: This study assesses the ecological sustainability of different fish farming systems (semi-natural, concrete, and galvanised ponds) in the Sistan region using emergy footprint accounting method. The findings suggest that semi-natural ponds have a higher ecological surplus but cause more adverse effects on non-renewable environmental resources compared to the other systems. Concrete and galvanised ponds have an ecological deficit and exert pressure on the surrounding ecosystem. Enhancing the efficient utilization of inputs in these ponds can improve their ecological safety and sustainability.

Summary: This study assessed the sustainability of FLOCponics, a system that combines biofloc-based aquaculture with hydroponics, and compared it to stand-alone biofloc and hydroponic cultures. The results suggest that FLOCponics uses low amounts of natural renewable resources, causes moderate environmental load, and is more efficient in terms of unit emergy values compared to hydroponics.

Summary: This study proposes an assessment method based on the emergy ecological footprint for marine ecological security evaluation. By measuring the emergy of the natural and economic elements of the marine ecosystem, an ecological security evaluation index is constructed. A dynamic evaluation is conducted based on long time series data to reveal the change trend of ecological security. Using the Guangxi marine ecosystem as a case study, the results show that the ecosystem has been in an ecologically secure state but has experienced deteriorating conditions since 2010. Targeted suggestions are put forward based on the findings.

Summary: With the rapid development of China's port logistics industry due to economic globalization, concerns over increasing energy consumption and pollution emissions have prompted the need for ecological analysis. This study applies the theory of emergy analysis to improve the traditional calculation method of ecological footprint, and constructs an emergy-ecological footprint (EEF) model specifically for port logistics. By studying the ecological situation of Shanghai port logistics from 2009 to 2018, it is found that the energy footprint and pollution footprint are the major components of the ecological footprint. Despite the positive impact of port water logistics on natural resource development and ecological carrying capacity, Shanghai's port logistics still faces an ecological deficit. The study provides strategies and suggestions to improve the ecological situation, focusing on regulations, port facilities, collection and distribution structure, and awareness promotion. The findings not only contribute to the development of Shanghai's green port logistics but also provide valuable insights for other green ports.

Summary: This study examines the concept of circularity in the poultry supply chain by analyzing nitrogen flows in France. It finds that the poultry sector's nitrogen use efficiency has increased over time, but self-sufficiency remains low and imports have risen significantly. A significant portion of nitrogen inputs end up being lost to the environment. The study suggests two pathways to increase circularity: improving efficiency at each step of the supply chain and changing feed rations to incorporate more biowaste streams.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
