Summary: This paper provides a systematic summary of the occurrence of plastics, microplastics, and nanoplastics in landfill leachate and their interaction with other pollutants. It discusses the potential risks posed by microplastics in leachate, as well as the different technologies used for leachate treatment. The paper also highlights the limitations and challenges of existing microplastic removal techniques and calls for the development of new technologies to address this issue. This study serves as a scientific basis for further research on the fate of microplastics in landfill and leachate.

Summary: The study evaluates the efficacy of four different garbage enzymes prepared from fruit peels (pineapple, banana, orange, and lemon) in removing soluble chemical oxygen demand (sCOD) from landfill leachate at two temperatures (room temperature and higher temperature). The results showed that orange (10%) and lemon (15%) garbage enzymes had the highest sCOD reduction at room temperature. The study demonstrated that the garbage enzyme could increase the bioavailability of organics in leachate.

Summary: This study describes the collection and characterization of landfill leachate from different climatic zones in Sri Lanka. Membrane bioreactors (MBRs) with different configurations were used to treat the leachate, and the optimal operating conditions for the treatment were determined. The study highlights the capabilities of MBR in treating landfill leachate.

Summary: About 80-90 tons of municipal solid waste (MSW) in Mojokerto City, Indonesia, is disposed of into Randegan landfill daily. The research aims to determine the presence of microplastics (MPs) in the leachate of the landfill, its characteristics, and the removal efficiency of the leachate treatment plant (LTP). The average MP abundance in the raw leachate was 9.00 +/- 0.85 particles/L, with fiber shape dominating (64.44 %). The LTP achieved a MP removal efficiency of 75.6 %, but residual fiber-shaped MPs were still present in the effluent.

Summary: This study investigated the performance of TiO2 nanoparticles combined with aged waste reactors for treating landfill leachate. The optimal conditions for TiO2 synthesis were determined, and the removal rates for COD and color were explored under various conditions. The combination of TiO2 nanoparticles and aged waste reactors showed high removal efficiencies for NH4+-N and COD in leachate, with the potential for photocatalytic/biological combined treatment of landfill leachate.

Summary: This study evaluated the association between changes in physical-chemical parameters of leachate in on-site treatment systems and changes in PFAS concentrations. The results showed that RO systems significantly reduced both physical-chemical parameters and PFAS concentrations. Correlations were observed between changes in parameters and pH, alkalinity, ammonia, and metals.

Summary: This systematic review examines the current research on soil contaminants, specifically leachate from solid waste landfills, and emphasizes biological remediation. The study analyzes data on pollutant treatment by microorganisms and their results worldwide. Factors such as soil type, pollutant type, bacterial type, and study locations were considered. The review provides reliable global data on soil contamination, particularly by leachate from municipal landfills, and highlights the importance of considering various factors when selecting a viable remediation strategy.

Summary: In this study, Fe2O3 nanoparticles isolated from iron ore were used as adsorbents to effectively remove COD, color, and NH3-N from landfill leachate. The Langmuir isotherm model was found to be the most effective for adsorption, and the pseudo-second-order kinetic model fitted well with the elimination process. Thermodynamic analysis indicated that the removal of pollutants from landfill leachate using Fe2O3 nanoparticles occurred spontaneously and endothermically.

Summary: The emission of leachate from landfills is considered one of the main pollutants affecting ground and water environment. A comprehensive assessment showed that pollutants in leachate from the analyzed landfills remained at levels unsuitable for discharge to water or soil. The presence of substances harmful to aquatic environment may hinder the treatment process.

Summary: The SAARB demonstrated stable removal of organic matter and nitrogen from different landfill leachates, with microbial communities changing significantly after treatment. Microbial abundance and diversity were most affected by the content of refractory organics in the leachate, with Proteobacteria being the dominant microorganism. This study highlights the potential for optimization and application of SAARB in leachate treatment.

Summary: The disposal of pharmaceuticals and plastic waste produces contaminants of emerging concern (CECs) in landfill leachate. This study found that CECs, including pharmaceuticals and plasticizers, can persist in leachate many years after landfill closure. The transport of these compounds with landfill leachate is expected to continue as long as leachate is generated in the landfill.
