The rapidly increasing generation of municipal solid waste (MSW) threatens the environmental integrity and well-being of humans at a global level. Incineration is regarded as a technically sound technology for the management of MSW. However, the effective management of the municipal solid waste incineration (MSWI) ashes remains a challenge. This article presents the global dynamics of MSWI ashes research from 1994 to 2018 based on a bibliometric analysis of 1810 publications (research articles and conference proceedings) extracted from the Web of Science database, followed by a comprehensive summary on the research developments in the field. The results indicate the rapid growth of annual publications on MSWI ashes research, with China observed as the most productive country within the study period. Waste Management, Journal of Hazardous Materials, Chemosphere and Waste Management & Research, which accounted for 35.42% of documents on MSWI research, are the most prominent journals in the field. The most critical thematic areas on this topic are MSWI ashes characterisation, dioxin emissions from fly ash, valorisation of bottom ash and heavy metal removal. The evolution of MSWI ashes treatment technologies is also discussed, together with the challenges and future research directions. This is the first bibliometric analysis on global MSWI ashes research based on a sufficiently large dataset, which could provide new insights for researchers to initiate further research with leading institutions/authors and ultimately advance this research field.
城市固体废物（MSW）的快速增长在全球范围内威胁着环境的完整性和人类的福祉。焚烧被认为是管理 MSW 的一项技术成熟的技术。然而，城市固体废物焚烧（MSWI）灰的有效管理仍然是一个挑战。本文基于对从 Web of Science 数据库中提取的 1810 篇出版物（研究文章和会议录）进行的文献计量分析，介绍了 1994 年至 2018 年全球 MSWI 灰分研究的动态，并对该领域的研究进展进行了全面总结。结果表明，MSWI 灰分研究的年出版物数量迅速增长，中国是研究期间最具生产力的国家。《废物管理》、《危险物质杂志》、《化境》和《废物管理与研究》占 MSWI 研究文献的 35.42%，是该领域最突出的期刊。该主题最关键的专题领域是 MSWI 灰分特性、飞灰中二恶英排放、底灰增值和重金属去除。还讨论了 MSWI 灰分处理技术的演变，以及挑战和未来的研究方向。这是基于足够大数据集对全球 MSWI 灰分研究进行的首次文献计量分析，可为研究人员提供新的见解，以便与领先机构/作者一起开展进一步的研究，并最终推动该研究领域的发展。
