Summary: This study investigates the feasibility of water injection technology in reducing knock tendency of GDI engines through numerical simulation methods. It is found that using LPNA water injector arrangement can effectively reduce knock intensity. Additionally, the results show that when the water injection pressure is 5 bar, the engine experiences minimum knock intensity, highest cycle work, and lowest emissions.

Summary: A comparative life cycle assessment is performed to evaluate the environmental sustainability of methanol production processes. The study finds that thermochemical CO2 hydrogenation (TC) and electrochemical CO2 reduction (EC) pathways have higher impact scores in global warming, terrestrial ecotoxicity, human non-carcinogenic toxicity, and fossil resource scarcity. The integration of recycling streams in the process flows is highlighted as an effective way to reduce environmental burden. Renewable electricity sources can significantly decrease the impact potentials of TC and EC pathways. The study underscores the importance of developing emerging technology for sustainable fuel production and provides insights into the future direction of methanol production from CO2.

Summary: Around half a million tonnes of spent nuclear fuel will be in storage by 2050. Continuing storage is not sustainable, and disposal or recycling is necessary. International studies have evaluated the advantages and disadvantages of these options in terms of economic, environmental, and societal impacts. Economic assessments show that the costs of managing spent fuels have a relatively minor impact on the overall cost of the nuclear fuel cycle.

Summary: The study conducted a comprehensive exergetic analysis of hydrogen fuel utilization in medium-scale aircraft turboprop engines and compared it with jet fuel utilization. Results showed that hydrogen fuel reduced fuel mass stream rate and pollutant emissions, while increasing overall system fuel exergy rate. However, the sustainability performance and environmental effects of the system decreased with hydrogen fuel usage.

Summary: This study analyzes the EU demand for PET packaging and quantifies the potential environmental and societal savings through changing waste management and consumption patterns. The results show that implementing more efficient waste management systems and a robust secondary material market can lead to significant reductions in CO2 emissions and PM2.5 emissions, while also avoiding high societal costs. Limiting the growth of PET consumption can also improve waste management efficiency and save on emissions and societal costs.

Summary: Hydrogen fuel cells are becoming increasingly important for electric vertical take-off and landing aircraft, offering potential solutions to the challenges faced by batteries. While previous studies have explored their feasibility for urban air mobility, there is still a need for a comprehensive assessment of their environmental impact. This study adopts a model-based life cycle engineering approach to quantify the environmental impacts of a fuel cell system designed for three different ranges. The findings reveal that, in the best-case scenario, 70g CO2-eq. per passenger-kilometer can be achieved. The environmental impacts are primarily attributed to the fuel cell stack in cases of green hydrogen production, while non-renewable hydrogen production pathways result in hydrogen having the highest impact contributions. Although systems designed for longer ranges may increase attractiveness in the future, better environmental performance is observed in systems with shorter design ranges.

Summary: This study compares the energy consumption and Greenhouse Gas (GHG) emissions of advanced asphalt pavement constructions using self-healing, steel slag recycling, and warm mix technology. Results show that warm mix asphalt pavement is the most environmentally friendly overall, but the environmental burdens generated in materials extraction stage are significant. Factors such as recycled materials applications, transport distance managements, and located climate conditions have a striking impact on the environmental effects of asphalt pavement construction.

Summary: Due to the environmental damage caused by ship pollutants, regulations are being strengthened to reduce air pollution and new technologies are being developed for the use of eco-friendly fuels. Liquefied petroleum gas (LPG) is an attractive fuel option that can bridge the transition to zero-carbon ships. This study quantitatively analyzed the fuel consumption costs and air pollutant reductions by using LPG fuel in South Korean registered ships, finding significant reductions in both areas. Promoting the use of LPG, particularly for fishing vessels, is necessary through government policies and price subsidies.

Summary: This study critically reviews Life Cycle Assessment (LCA) studies on lightweight materials for automotive chassis and body-in-white components, identifying A/HSS and Al as the most preferable materials. Primary and secondary mass reductions, recycling rates, and driven distances are crucial hotspots. The study recommends future research to provide clearer data, consider other impact categories, and use consequential LCA to assess market uptake.

Summary: The use of bioprocesses in industrial production offers resource- and energy-efficient processes with renewable, nonfossil feedstocks. However, the environmental benefits of early-stage bioprocess development need to be demonstrated using standardized methods such as life cycle assessment (LCA). This article discusses selected LCA studies of early-stage bioprocesses, highlighting their potential and contribution to estimating environmental impacts and decision support. Recommendations are provided for addressing challenges in conducting LCAs of early-stage bioprocesses and opportunities are identified for future applicability, such as establishing dedicated bioprocess databases for the use of LCAs as standard tools among bioprocess engineers.
