Waste to Energy from Municipal Wastewater Treatment Plants: A Science Mapping

Abstract: Energy recovery, according to circular economy and sustainable principles, has established itself as an inevitable field of action in wastewater treatment plants (WWTPs). Energy costs are forcing the optimization of processes and increases in the development of applicable waste-to-energy (WtE) technologies. This study aims to analyze the existing knowledge on WtE research in municipal WWTPs using a systematic literature review and a bibliometric analysis from 1979 to 2021. For this purpose, Science Mapping Ana… Show more

“…Performance analysis is used to analyze the output of research on any scientific subject [ 43 ]. Science or bibliometric mapping, on the other hand, finds outs relationships between various parts of the research components and enables to assess documents, references, authors, organizations and productivities of countries [ [44] , [45] , [46] ]. Moreover, science mapping analysis “aims to visually present and display the conceptual, social or intellectual structures of scientific research, and the evolution, development, and dynamics of the research area” [ 47 ].…”
