Comparisons among recycling technologies have identified current research trends, including a focus on pretreatment technologies for waste materials and the development of new organic chemistry or biological techniques that enable recycling with minimal energy consumption. Existing environmental and economic studies are also compared. The findings highlight differences in the environmental characteristics of various recycling methods, including their ability to recover plastic resins, carbon footprint, electricity consumption and gas emissions. The comparisons also reveal the challenges associated with these methods: mechanical recycling often encounters economic barriers due to contamination and inefficiencies in sorting and cleaning processes; thermolysis is constrained by high energy demands and operational costs, whereas chemical and biological recycling faces limitations related to scalability and material costs. Additionally, current challenges, emerging research areas and future directions in plastic recycling are discussed. For example, the role of innovative techniques, such as artificial intelligence, in refining recycling processes is emphasized. The importance of incorporating circular economy principles in the integrated sustainable analysis of recycling processes is also highlighted. The innovative contribution of this review is to address both technological developments and their environmental and economic implications. The focus is placed on literature from the past 10 years to ensure coverage of the most recent advancements. Overall, the insights of this review article aim to guide researchers, policymakers and industry stakeholders in improving sustainable management practices for plastic waste.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"734242X241310658"},"PeriodicalIF":3.7,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143012066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article provides a comprehensive review of global plastic waste management (PWM) strategies, focusing on advancements in processing technologies, policy frameworks and their practical applications. It highlights the role of the World Intellectual Property Organization (WIPO) and regulatory bodies across the United States, Canada, Europe, Britain, India, Japan, Australia and China in fostering sustainable PWM practices. The study evaluates key processing techniques, including pyrolysis, gasification, supercritical water conversion, plasma-assisted processes, mechanical reprocessing and landfilling, emphasizing their technological advancements, limitations and scalability. Supercritical water conversion (operating at >374°C and 22.1 MPa) and plasma-assisted processing (using ionized gas at >3000°C) are identified as advanced methods capable of converting plastics into simpler molecules or valuable by-products. However, these technologies face challenges such as high energy requirements, operational costs and limited scalability. Persistent issues, including microplastic pollution, environmental impacts and the chemical-intensive nature of certain processes, are critically analysed. Drawing on extensive reviews of patents, case studies and real-world implementations, the study also examines the reuse potential of plastic by-products in diverse industries and evaluates state-level PWM initiatives in India. This review provides actionable insights for policymakers, researchers and industry stakeholders, highlighting critical gaps and opportunities to enhance the sustainability and scalability of PWM systems. By addressing persistent challenges, it contributes to advancing a circular economy for plastics and sustainable waste management practices globally.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"734242X241308499"},"PeriodicalIF":3.7,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142955905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on literature, the history of thermal waste treatment over the last 150 years is investigated, from open burning to WtE with resource recovery and final sink function. The results show that in the past incineration solved the issues it was designed for but often created new and sometimes even worse problems: The introduction of incineration in the 19th century improved urban sanitation, decreased waste volume and prolonged operational life of landfills. But it also polluted the environment, triggering an unprecedented scientific and engineering effort of all stakeholders. Today, WtE is one of the best investigated and optimized technologies in waste management. It enables the recovery of energy as heat and electric power and facilitates the 'cleaning' of cycles by the destruction of hazardous organic substances. Recent developments in resource recovery from WtE residues allow to recycle metals and, in the case of sewage sludge, even phosphorus by thermal recycling. Combined with carbon capture and storage technology, WtE stands for a quantifiable contribution to greenhouse gas reduction. Today, WtE is indispensable to reach the goals of CE, namely recycling of energy and materials, supplying safe final sinks for persistent organic substances and minimizing the need for sinks for hazardous inorganic substances.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"26-38"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11690026/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139571470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though these countries' urban local bodies (ULBs) are moving up the waste management hierarchy, most waste is still openly dumped. One key reason for this choice is the non-accounting of (a) social costs associated with open dumping (OD) and (b) direct/indirect benefits of other options. The current study conducts a complete social cost-benefit analysis (SCBA) comparing OD to sanitary landfilling, composting, bio-methanation, incineration and gasification alternatives. The study finds that when only private costs/benefits are considered, a mix of OD and sanitary landfills is preferred; however, when external costs/benefits are factored in, the mix shifts towards alternatives like incineration and gasification. These learnings from the SCBA are then applied to Mumbai, which generates 9000 tonnes of waste daily. To determine the optimal mix for Mumbai ULB, a constrained optimization exercise is carried out considering the technical feasibility of the alternatives and the ULB's capital budget. The study finds that with the current practice of OD, the net present value (NPV) of the social costs over a 30-year horizon will be over US$ 6-9 billion. However, even if one-fifth of the ULB's capital budget is allocated towards other waste management alternatives, the mix would shift towards sophisticated technologies and the NPV of social costs would reduce to around half that amount.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"39-49"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139933125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This manuscript traces the paradigm shift from the foundational Basel Convention of 1989 to the significant sway of World Health Organization publications on contemporary debates. Utilizing a mixed approach strategy that blended qualitative and quantitative techniques, the research employed extensive literature review, co-citation and co-word analysis methodologies to ascertain the direction of contemporary trends in MWM. Within the scope of the research findings, current strategies reveal noticeable gaps, especially those that lack sound policy structures, comprehensive insights and effective operational frameworks. Co-citation evaluations spotlight predominant themes in academic references. Foremost among them are the socioeconomic factor, environmental significance, medical waste (MW) stabilization and sustainable society, sequenced by cluster magnitude. Co-word analysis unveils that, despite the long-standing presence of incineration plants, pyrolysis has, since 2016, prioritized environmental considerations. The recycling ethos peaked in 2014, but the sustainability paradigm burgeoned in 2020, with the 'circular economy' gaining momentum in 2021. Emerging trend analysis underscores the mounting significance of circular waste technologies and sustainability as indispensable solutions. Results demonstrate MW advancements and highlight emerging trends shaping the future of the field. The research concludes by accentuating the necessity of global collaborative efforts, integrating cutting-edge technologies and infusing sustainability and circularity tenets into societal frameworks to navigate MWM's intricate landscape. Future research trajectories, including wastewater governance, novel mobile waste disposal strategies and a cyclic waste classification paradigm, are proposed.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"3-15"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11697513/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139730543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recycling spent Cd-enriched adsorbents into efficient catalysts for advanced applications could address the environmental issues and attain the carbon neutral goal. Herein, a facile strategy is developed for the first time to reutilize the alkali lignin (AL)-derived biochar (ALB) absorbed with Cd into cadmium sulphide (CdS)/C composite for the efficient methylene blue (MB) removal. The ALB is initially treated with Cd-containing solution, then the recycling ALB samples with adsorbed Cd are converted to the final CdS/C composite using NaS2 as the sulphurizing reagent for vulcanization reaction. The optimal ALB400 demonstrates a high adsorption capacity of 576.0 mg g-1 for Cd removal. Then the converted CdS/C composite shows an efficient MB removal efficiency of 94%. The photodegradation mechanism is mainly attributed to carbon components in the CdS/C composite as electron acceptor promoting the separation of photoelectrons/holes and slowing down the abrasion of CdS particles. The enhanced charge transfer and contact between the carrier and the active site thus improves the removal performance and reusability. This work not only develops a method for removing Cd from wastewater effectively and achieving the waste resource utilization but also further offers a significant guidance to use other kinds of spent heavy metal removal adsorbents for the construction of low-cost and high value-added functional materials.","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"75-85"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139933123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The considered supply chain consists of the government, two manufacturers, a supplier, a waste depot, and a recycler. Under this structure, two substitutable products are made of the virgin and recyclable waste materials. The supplier provides the virgin materials for the first product. The waste depot collects the non-recycled waste, whereas the recycler recycles it and supplies the recycled waste for the second product. Also, the government supports the second product to provide an incentive for its members to collect and recycle more waste. Then, the game theory is applied to make decisions under the considered structure. Finally, the results are revealed and some managerial insights are provided.
