Introduction

This study explores the barriers and enablers influencing the adoption of circular economy principles within waste management systems, using a case study from Portugal. It highlights the complex interplay of regulatory frameworks, economic incentives, technological readiness, and public engagement in transitioning from linear to circular models. Understanding these factors is crucial for designing effective policies and strategies to promote sustainable waste practices [1].

This review provides an overview of recent advancements in membrane-based technologies for wastewater treatment and resource recovery. It discusses various membrane types, configurations, and applications, emphasizing their potential for efficient pollutant removal and the extraction of valuable resources like water and nutrients. The article addresses challenges such as fouling and energy consumption, pointing towards future research directions for optimizing these technologies [2].

This comprehensive review delves into the landscape of chemical recycling processes for plastic waste, crucial for transitioning to a circular economy. It examines various chemical methods like pyrolysis, gasification, and solvolysis, evaluating their effectiveness in depolymerizing plastics back into monomers or valuable fuels. The article highlights the advantages of chemical recycling over mechanical methods for mixed or contaminated plastic waste, while also discussing the technological hurdles and economic viability [3].

This review focuses on the application of advanced oxidation processes (AOPs) for the removal of emerging contaminants from landfill leachate. It details different AOPs, such as Fenton, photo-Fenton, ozonation, and photocatalysis, assessing their efficiency in degrading persistent organic pollutants and pharmaceuticals. The paper highlights the complex composition of leachate and the need for robust treatment technologies to mitigate environmental risks associated with these hazardous substances [4].

This comprehensive review explores current and future trends in waste-to-energy (WtE) technologies, essential for sustainable waste management. It covers various WtE approaches including incineration, gasification, pyrolysis, and anaerobic digestion, analyzing their operational principles, environmental impacts, and energy recovery potential. The article provides insights into optimizing these technologies for different waste streams and integrating them into broader energy systems to reduce landfill reliance and produce renewable energy [5].

This review provides an in-depth analysis of microplastics removal from wastewater, examining current technologies and future perspectives. It discusses the sources and impacts of microplastics, followed by a critical assessment of primary, secondary, and tertiary treatment methods, including coagulation-flocculation, membrane filtration, and biological processes. The paper emphasizes the need for advanced and integrated approaches to effectively mitigate microplastic pollution in aquatic environments [6].

This comprehensive review explores the challenges and opportunities in electronic waste (e-waste) management, a growing global concern. It covers the environmental and health impacts of improper e-waste disposal, current legislative frameworks, and various recycling technologies. The article highlights the potential for resource recovery from e-waste, stressing the importance of developing sustainable collection, dismantling, and processing systems to foster a circular economy for electronics [7].

This critical review evaluates bioreactor landfills as a sustainable approach for solid waste management. It discusses how these engineered systems enhance waste decomposition, accelerate stabilization, and facilitate landfill gas recovery, offering significant environmental and economic benefits compared to conventional landfills. The article also addresses operational challenges, design considerations, and performance monitoring crucial for the successful implementation of bioreactor technology [8].

This review explores the integration of circular economy principles into urban solid waste management, outlining both the challenges and opportunities. It examines strategies such as waste prevention, reuse, recycling, and resource recovery within an urban context, emphasizing their potential to reduce environmental impact and create economic value. The article highlights policy instruments, technological innovations, and stakeholder collaboration as key drivers for successful circularity in urban waste systems [9].

This review comprehensively discusses advanced treatment technologies for removing emerging contaminants (ECs) from industrial wastewater. It covers a range of physical, chemical, and biological methods, including membrane processes, advanced oxidation processes, and bioremediation, evaluating their efficacy and limitations for diverse industrial effluents. The article underscores the complexity of ECs and the necessity for innovative and combined approaches to ensure effective wastewater purification and environmental protection [10].

Conclusion

Current research emphasizes the critical need for sustainable waste management and the widespread adoption of circular economy principles. Studies identify key barriers and enablers, from regulatory frameworks to public engagement, that influence the successful transition from linear to circular models, particularly within urban waste systems. Innovation in waste prevention, reuse, recycling, and resource recovery is highlighted as essential for reducing environmental impact and creating economic value. A significant body of work focuses on advanced treatment technologies for various contaminants. Membrane-based systems are proving effective for wastewater treatment and resource recovery, adept at removing pollutants and recovering valuable nutrients. Advanced Oxidation Processes (AOPs) are instrumental in degrading emerging contaminants from landfill leachate and industrial effluents. Furthermore, comprehensive reviews detail methods for microplastics removal from wastewater, underscoring the need for integrated treatment approaches. Recycling specific waste streams is also a major theme, with chemical recycling offering a promising pathway for plastic waste valorization. Electronic waste management, a growing global challenge, is explored for its substantial resource recovery potential through optimized collection and processing. Lastly, waste-to-energy (WtE) technologies and bioreactor landfills are presented as sustainable alternatives, aiming to reduce landfill dependence, generate renewable energy, and enhance waste decomposition. These collective efforts underscore a concerted global drive toward innovative and integrated solutions for a more sustainable future.
