Abstract

The usage of Municipal Solid Waste Incineration Fly Ash (MSWI FA) for ex-situ carbon mineralization has received increasing attention to address the challenge from carbon neutrality and sustainability. Recent studies have focused on aqueous reactions for the stabilization and carbon sequestration of MSWI FA, while there lacks an optimized strategy for the various mineralization techniques proposed in literature. This review presents the first comprehensive summary of recent advancements in ex-situ carbon stabilization using MSWI FA with aqueous reactions, based on an analysis of 1284 publications pre-filtered by Large Language Models (LLM) and manually screened. Focusing on carbon capture capacity of MSWI FA, this review proposes a unified formula to estimate the theoretical maximum carbon uptake, and provides the first in-depth comparative analysis of carbon sequestration efficiency for various carbonation techniques, together with evaluations on the environmental impacts through their heavy metal stabilization efficiency. Furthermore, this review examines the global landscape of carbon capture and identifies MSWI FA carbonation as a highly promising short-term solution due to its cost-effectiveness and carbon uptake potential.

城市生活垃圾焚烧飞灰先进的非原位碳稳定技术综述

利用城市生活垃圾焚烧飞灰（MSWI FA）进行非原位碳矿化，以解决碳中和和可持续性的挑战，已受到越来越多的关注。最近的研究主要集中在水反应中稳定和固碳的MSWI FA，而文献中提出的各种矿化技术缺乏优化策略。本文基于对1284篇经大型语言模型（LLM）预过滤和人工筛选的论文的分析，首次全面总结了利用MSWI FA进行水反应的非原位碳稳定研究的最新进展。本文以MSWI FA的碳捕获能力为研究重点，提出了统一的理论最大碳吸收量估算公式，并首次对各种碳化技术的固碳效率进行了深入的比较分析，并通过其重金属稳定效率对环境影响进行了评价。此外，本综述考察了碳捕获的全球格局，并确定由于其成本效益和碳吸收潜力，MSWI FA碳化是一种非常有前途的短期解决方案。

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
