Summary: The global demand for green energy has led to the popularity of electric vehicles and the need for lithium-ion batteries (LIBs). However, the current recycling methods for LIBs are either energy-intensive or highly complicated. As the market trend shifts towards cobalt-poor or cobalt-free chemistry, alternative non-destructive methods such as direct recycling and upcycling have gained interest.

Summary: China is the largest producer of aluminum in the world, resulting in the generation and storage of vast quantities of aluminum dross annually. However, due to a lack of developed technologies, most of this dross cannot be safely treated, leading to a waste of resources and serious environmental and ecological risks. This review briefly describes the distribution and proportions of bauxite deposits in China, the aluminum extraction process, and the hazardous solid waste that is generated. It also discusses comprehensive treatments for aluminum dross, including the recovery processes of hydrometallurgy and pyrometallurgy, and the reuse of aluminum, aluminum oxide, silicon dioxide, and chloride salts, providing a summarized comparison of their advantages and disadvantages. The review focuses on analyzing the relationship between existing processes and attempts to establish a comprehensive technology for treating aluminum dross, and suggests areas for future research that may provide new ideas for the closed-loop treatment of aluminum dross.

Summary: The objective of this review is to evaluate various aspects of aluminium dross, including its generation, classification, properties, applications, and recycling techniques. Aluminium dross, a by-product of the aluminium industry, is recycled through pyrometallurgy, hydrometallurgy, and hydrothermal processes to recover aluminium and generate valuable products. Pyrometallurgy, particularly through Rotary salt furnace and salt-free technologies, dominates the industrial scale recycling. On the laboratory research front, hydrometallurgy and hydrothermal processes show promise. These processes produce products such as zeolites, ion exchangers, molecular sieves, and layered double hydroxides, as well as gases like H2, CH4, and NH3. The advantages and disadvantages of each route determine their applicability. Investigation of each route is vital due to the abundance of modern technologies emphasizing aluminium dross recycling. This recycling also contributes to the preservation of natural resources and addresses the adverse effects of improper dross disposal on human health and the environment.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
