From garbage to global warming: a bibliometric analysis of greenhouse gas emissions from municipal solid waste and its relationship with climate change

Municipal solid waste (MSW) management significantly impacts carbon footprint due to greenhouse gas emissions from open dumping and improper management. In this study, we have examined the current state of research on greenhouse gas emission from MSW and their impact on climate change and further analysed the published literature based on different bibliometric and network analysis indices. The result of this study indicates a steady increase in the number of scientific literature on this topic over the last 28 years. Among different countries, China has contributed the highest number of documents and received the highest number of citations. The Technical University of Denmark was the most productive among different institutions worldwide. Keyword clustering and network analysis have identified several emerging topics, such as modelling approach to reduce GHG emissions from MSW dump yards and powerplants. The network analysis also identified that global collaborative research is indispensable in the foreseeable future.
