Summary: Energy security and energy trade are crucial for global economic and social development. The robustness of the international oil trade network (iOTN) is vital for the global economy. Using machine learning optimization algorithm, game theory, and utility theory, we developed a decision-making model for oil trade that considers the benefits and costs of economies involved. We reconstructed and analyzed the iOTN to verify the model's effectiveness. Policy simulations based on game theory and agent-based model were conducted to understand the impact of external shocks and trade friction costs on oil trade. The study found that export-oriented economies are more vulnerable and the effects of trade friction costs are asymmetrical with significant differences between international organizations.

Summary: Freshwater is crucial for human well-being and sustainable development, but its unequal distribution leads to shortages. By discussing the limitations of existing freshwater transfer methods, it is suggested that international freshwater trade is necessary to alleviate scarcity. However, establishing a global freshwater market faces several challenges.

Summary: This paper investigates the implications of a country's dependence on renewable energy consumption in total energy use for international trade. The findings suggest that renewable energy use reduces the competitiveness of trade, leading to a decrease in exports and an increase in imports. However, there is heterogeneity in these effects between OECD and non-OECD countries.

Summary: This article aims to assess the consequences of policies to reduce the environmental impact of agricultural trade. It found that some of these policies could cause instability in the short/medium run and have permanent adverse effects on competitor countries. The study suggests that instability could be reduced by providing information to improve price forecasting and adverse effects could be prevented through coordinated sustainable policies among competitor countries.

Summary: Sugarcane has become an important renewable raw material that can potentially reduce greenhouse gas emissions and decrease the dependence on fossil fuels. Brazilian government policies have created favorable conditions for the establishment of the first sugarcane biorefinery, which aims to produce biofuels, sugar, and bioelectricity in a sustainable and cost-effective manner. The development of 2G and 3G technologies further expands the potential of sugarcane for producing value-added biochemicals and reducing emissions through integrated systems with a non-waste vision and circular bioeconomy.

Summary: Stock market price prediction is crucial for investment and consumption planning, especially in the context of the COVID-19 pandemic. A two-phase framework is proposed to forecast oil, coal, and natural gas prices in India, both pre-and post-COVID-19. Empirical results suggest that the Autoregressive Integrated Moving Average method is suitable for predicting the prices of these energy resources. Furthermore, the predictive precision is higher in the pre-COVID-19 period compared to the post-COVID-19 stage, and prices are forecasted to increase until 2025.

Summary: A consolidation process involving the addition of surfactant and cell immobilization was used to improve ethanol production from food waste. Results showed that the optimum glucose concentration for ethanol fermentation was 200 g/L. By adding 0.5% Tween 80, ethanol production was significantly improved. In a cell-immobilized system using wheat straw as a carrier, high ethanol production was achieved. Calculations also showed that food waste was a suitable substrate for ethanol production.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.

Summary: This paper studies the thermal stability and decomposition of cork materials with and without silica aerogel filler. The results show that the decomposition is inhibited and the pyrolysis is significantly reduced with the addition of silica aerogel. This finding suggests that silica aerogel-infused cork may be a promising raw material for biofuel production with reduced environmental pollution.
