Solid waste increase is inevitable globally due to anthropogenic activities. This adds burden to waste management systems in developing countries including Zimbabwe. Currently, life cycle assessment (LCA) model is used to achieve sustainability and circular economy (CE) in solid waste management. Therefore, the main goal of this paper was to unearth LCA model applicability in solid waste management in Zimbabwe. Data sources were retrieved from databases like Scopus, ScienceDirect and Springer, although government documents were also used. In Zimbabwe, organic and inorganic solid waste is generated from various sources, namely industries, institutions and households. Solid waste management in Zimbabwe is based on traditional linear approach where waste is collected and disposed through landfilling, burning, incineration, burying, open pits or illegally. Most disposal approaches occupy base of waste management pyramid, hence posing detrimental impacts to human health, terrestrial, aquatic and atmospheric ecosystems. Management approaches are far from Agenda 21, Sustainable Development Goals (SDGs), Zimbabwe Vision 2030 and National Development Strategy 1 demands. Literature revealed that LCA model can be utilised to achieve sustainable solid waste management in countries like Zimbabwe. LCA model is essential in management of solid waste in Zimbabwe, since it assists decision makers in selecting management approaches with less environmental health impacts. Moreover, LCA enables application of waste material reuse, recycle, repairing and recovery, thus narrowing the gap to achieve CE and economic growth in Zimbabwe. Owing to LCA model implementation of waste management legislation and policies which support energy recovery and circular economy became easier in Zimbabwe.
由于人为活动，全球固体废物增加是不可避免的。这给包括津巴布韦在内的发展中国家的废物管理系统增加了负担。目前，生命周期评估（LCA）模型用于实现固体废物管理的可持续性和循环经济（CE）。因此，本文的主要目标是挖掘LCA模型在津巴布韦固体废物管理中的适用性。数据来源从Scopus、ScienceDirect和Springer等数据库检索，不过也使用了政府文件。在津巴布韦，有机和无机固体废物来自各种来源，即工业、机构和家庭。津巴布韦的固体废物管理基于传统的线性方法，即通过填埋、焚烧、露天坑或非法方式收集和处置废物。大多数处置方法占据了废物管理金字塔的底部，因此对人类健康、陆地、水生和大气生态系统造成有害影响。管理方法远未达到《21世纪议程》、可持续发展目标（SDGs）、《津巴布韦2030年愿景》和《国家发展战略1》的要求。文献表明，LCA模型可用于在津巴布韦等国家实现可持续的固体废物管理。LCA模型在津巴布韦的固体废物管理中至关重要，因为它有助于决策者选择对环境健康影响较小的管理方法。此外，LCA能够应用废物材料的再利用、回收、修复和回收，从而缩小差距，在津巴布韦实现循环经济和经济增长。由于LCA模型的实施，在津巴布韦支持能源回收和循环经济的废物管理立法和政策变得更加容易。
