Abstract

The present study focuses on a bibliometric analysis of the global production of scientific papers related to the recovery of bioenergy from orange industrial waste or by-products. The study also observed the top-cited papers, international collaborative networks, top countries, and journals. The timespan was from 1900 to 2019, and the Web of Science© database was used. A total of 161 documents (research and review papers) were selected to carry out the investigation. Two main clusters of literature were highlighted, related to the authorship of the top-cited papers and authorship collaboration networks, respectively. Recent scientific publications use different pre-treatments to achieve the best biogas yield with many configurations of the anaerobic digestion system. The data indicated that the countries with most publications are Spain, China, and the USA, and the journals with a higher impact factors related to environmental assessments were responsible for a higher number of publications. In a biorefinery concept, orange peel could be submitted to different pre-treatments to produce bioethanol and methane, as environmentally friendly fuels, and other co-products such as d-limonene and pectin. This study therefore presents trends in bioenergy production from orange industrial by-products with the aim of supporting further research on energy recovery from orange industry solid waste and to assist future decision making in this field of science. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd
