Abstract：
The rapid urbanization witnessed in developing countries in Asia and Africa has led to a substantial increase in municipal solid waste (MSW) generation. However, the corresponding disposal strategies, along with constraints in land resources and finances, compounded by unorganized public behaviour, have resulted in ineffective policy implementation and monitoring. This lack of systematic and targeted orientation, combined with blind mapping, has led to inefficient development in many areas. This review examines the key challenges of MSW management in developing countries in Asia and Africa from 2013 to 2023, drawing insights from 170 academic papers. Rather than solely focusing on recycling, the study proposes waste sorting at the source, optimization of landfill practices, thermal treatment measures, and strategies to capitalize on the value of waste as more pertinent solutions aligned with local realities. Barriers to optimizing management systems arise from socio-economic factors, infrastructural limitations, and cultural considerations. The review emphasizes the importance of integrating the study area into the circular economy framework, with a focus on enhancing citizen participation in solid waste reduction and promoting recycling initiatives, along with seeking economic assistance from international organizations.
摘要：
亚洲和非洲发展中国家的快速城市化导致城市固体废物(MSW)产生大幅增加。然而,相应的处置策略，加上土地资源和财政的限制，加上无组织的公共行为，导致政策执行和监督不力。这种缺乏系统性和针对性,结合盲映射，导致许多领域的发展效率低下。这篇综述探讨了2012年至2022年亚洲和非洲发展中国家城市生活垃圾管理的主要挑战，并从171篇学术论文中汲取了见解。而不是仅仅专注于回收利用，这项研究建议从源头进行废物分类，优化填埋做法，热处理措施,以及利用废物价值的战略，将其作为与当地现实相一致的更相关的解决方案。优化管理体制的障碍来自社会经济因素，基础设施限制，和文化考虑。研究强调了将研究区纳入循环经济框架的重要性,重点是加强公民对减少固体废物的参与和促进回收倡议，同时寻求国际组织的经济援助。
