Summary: With the increasing plastic waste and decreasing fossil energy, pyrolysis has emerged as a promising technology for converting plastic waste into fuels and chemicals. This review discusses the properties of common plastics, the pyrolysis mechanism, and the product distribution. Catalysts, such as zeolites, base catalysts, and clays, have shown advantages over thermal cracking. Upgrading and further utilization of the liquid fuels and non-condensable gas co-product are necessary before commercial application. The review emphasizes the importance of techno-economic assessment and aims to inspire research efforts in creating a circular economy.

Summary: In this study, the hydro-thermal and mass transport characteristics of a non-homogeneous micropolar mixture were numerically analyzed. The results showed that the micropolarity and electrically conducting properties of the nanofluid play a significant role in enhancing its motion. Furthermore, it was observed that the thermophoresis diffusive mechanism can be further enhanced by the presence of an internal heat source in the convective heating process.

Summary: This paper contributes to the literature by examining the effects of scale and technique on renewable energy consumption, taking into account foreign direct investment (FDI) and financial development. The empirical results show a positive correlation between financial development and renewable energy consumption, as well as a positive correlation between FDI and renewable energy demand. Composition effects have a negative impact on renewable energy consumption. Long-term estimation results indicate a U-shaped relationship between renewable energy-FDI and renewable energy-financial development associations.

Summary: This paper presents a new framework for scheduling microgrids and distribution feeder reconfiguration, considering uncertainties from load demand, market price, and renewable power generation. The framework consists of a two-stage model, where the self-scheduling of microgrids is optimized in the first stage and the optimal configuration of the system is determined by the distribution system operator in the second stage. The results show that the deviation from optimal microgrid scheduling is significantly reduced when the system is reconfigured by the operator.
