This article presents a systematic review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method associated with a bibliometric analysis on global perspective of technological advances in waste-to-energy (WTE). OpenRefine and VOSviewer software supported the bibliometric analysis. It was possible to establish the scientific gap through the correlation among interactions observed on co-authored countries’ analyses, cited sources of co-citation, cited authors of co-citation, and keyword of the co-occurrence author. A total of 10 papers were included for meta-analysis and categorized into 8 fields: author(s), title, published year, research areas, energy conversion technologies, wastes used for energy production, WTE products, key findings. Considering the end use of the products, the systematic literature review confirmed a limitation of research focusing on the opportunities for a cleaner transport sector. When analysing the author’s keywords, the most cited were ‘municipal solid waste’, ‘incineration’, ‘waste management’, ‘gasification’, ‘anaerobic digestion’, ‘combustion’, ‘waste-to-energy’, ‘landfill gas’, and ‘sustainability’, noting that the studies were directed at economic and sustainable development, as well as circular economy, aiming to mitigate adverse environmental impacts. As can be seen from the systematic review associated with the bibliometric analysis presented, the waste to energy technology is an important innovation way or route that finds numerous applications in the transport and energetic sector. It was evidenced that the WTE research efforts are mainly focused on the conversion of waste for end use electricity generation. The main role of WTE technologies in the circular economy is the energy recovery from biomass and non-recyclable waste, and also it was presented as a viable alternative to the decarbonization of transport and energy sectors.

本文使用系统评价和元分析的首选报告项目 (PRISMA) 方法对文献进行了系统回顾，该方法与废物转化能源 (WTE) 技术进步的全球视角相关的文献计量分析。OpenRefine 和 VOSviewer 软件支持文献计量分析。通过在共同作者国家的分析中观察到的相互作用、共同引用的引用来源、共同引用的引用作者和共同作者的关键词之间的相关性，可以建立科学差距。共纳入 10 篇论文进行元分析，分为 8 个领域：作者、标题、发表年份、研究领域、能源转换技术、用于能源生产的废物、WTE 产品、关键发现。考虑到产品的最终用途，系统的文献综述证实了关注更清洁运输部门机会的研究的局限性。在分析作者的关键词时，引用最多的是“城市固体废物”、“焚烧”、“废物管理”、“气化”、“厌氧消化”、“燃烧”、“垃圾发电”、“垃圾填埋气”和“可持续性”，指出这些研究针对经济和可持续发展以及循环经济，旨在减轻不利的环境影响。从与文献计量分析相关的系统评价可以看出，废物转化为能源技术是一种重要的创新方式或途径，在运输和能源领域有许多应用。有证据表明，WTE 研究工作主要集中在废物转化为最终用途发电。WTE 技术在循环经济中的主要作用是从生物质和不可回收废物中回收能源，并且它被认为是交通和能源部门脱碳的可行替代方案。
