The exponential generation of municipal solid waste (MSW) and landfill disposal without any treatment has increased the continuous generation of landfill leachate. Improper MSW and leachate management are contributing to environmental degradation and water and soil pollution, which must be treated. Numerous works have been conducted on leachate treatments for energy and resource recovery. This review presents a comprehensive study of leachate management in which different treatment methods are discussed to analyze the suitability of processes that can be employed to treat leachate efficiently. Further, the characteristics of leachate are examined as properties of leachate may be varied depending upon the region. Still, several challenges related to leachate management and its treatments are discussed in this study. An integrated system could be a better option for treating leachate because it contains large amounts of organic and inorganic compounds. Proper leachate management would help to recover energy and value-added products (metals).

Additives leached from tire particles (TPs) after entering the marine environment inevitably interact with marine life. Marine heatwaves (MHWs) would play a more destructive role than ocean warming during the interaction of pollutants and marine life. To evaluate the potential risks of TPs leachate under MHWs, the physiological and nutrient metabolic endpoints of microalgae were observed for 7 days while being exposed to TPs leachate at current or predicted concentrations under MHWs.

In the past, unsanitary landfills were a common method for municipal solid waste disposal in developing countries. Although many nations have closed these landfills, the environmental pollution risks and impacts persist. This study introduces a new multi-criteria risk assessment framework specifically designed for closed, unsanitary landfills.

Phosphate mines produce large quantities of waste rock. These waste rocks are mixed and managed on the surface as large unrestored piles, which makes them difficult to rehabilitate. They primarily comprise carbonates, clays, marls, and cherts (flints).

Plastic pollution in aquatic environments poses significant ecological risks, particularly through released leachates. While traditional or non-biodegradable plastics (non-BPs) are well-studied, biodegradable plastics (BPs) have emerged as alternatives that are designed to degrade more rapidly within the environment. However, research on the ecological risks of the leachates from aged BPs in aquatic environments is scarce.

The evolution of energy structure and the push for carbon neutrality have triggered an urgent call for lithium-ion batteries (LIBs). However, reclaiming end-of-life LIBs with high purity, high efficiency, and low environmental impact, particularly by eliminating chemical reagent usage and promoting a closed-loop carbon footprint, is challenging. Herein, we proposed a strategy that couples the carbon capture (CC) process with an electrochemically enhanced membrane distillation system (ECMD).
