Proceedings of the International Conference on Industrial Engineering and Operations Management Manila, Philippines, March 7-9, 2023 3.1.1 Annual Scientific Production This graph is expected to present the trajectory of academic discourse on pulp and paper industry related to its (un)sustainable practices over the years. Given the recent global focus on sustainability on environmental, social as well as economic dimensions, it would be worthwhile to see if the academic community is at par with the global concern in identifying the issues of sustainability in pulp and paper industry and discussing the same with vigor. 3.1.2 Sources Description The plot on sources description will highlight the journals which are at the forefront in discussing the sustainability issue in pulp and paper industry and the journals which are not that active or are dormant. It would also be worthwhile to figure out whether the journals, which go by the nomenclature referring to sustainable or clean operations, truly are practicing what they preach. 3.1.3 Word Dynamics Whereas Word Frequency presents the most discussed word within the bibliographic collection, the plot Word dynamics presents the evolution of the words or concepts under discussion over a temporal scale. This plot will throw some light on the evolving words or concepts of concern related to sustainability, as perceived from the academic studies, plaguing the pulp and paper industry at any given point in time. 3.1.4 Thematic Evolution This plot was considered in the analysis as it would also throw light on the temporal evolution of the themes on discussion concerning sustainability in pulp and paper industry, quite similar to the Word Dynamics. 3.2 Content Analysis For the purpose of content analysis, the literature collection resulting out of the Scopus and Science Direct database search were inspected. Out of the entire bibliographic collection of 80 articles out of the search results, 20 relevant articles were considered for detailed study and content analysis for identification of challenges of sustainability in pulp and paper industry. The selection of articles were restricted to only 20, as the idea was to capture the most prominent and broadly discussed challenges in the literature, rather than going deep into specific engineering or technical evaluation of the challenges therein. 4. Results and Discussions 4.1 Bibliometric Analysis 4.1.1 Annual Scientific Production The time span of total number of 80 articles on the domain is 26 years with first article published in 1996 and last article under consideration being published in 2022 (Figure.1). The annual growth rate of the articles in the present field of interest over 26 years is 10.03%. A total of 259 authors have contributed cumulatively in these 80 articles. On an average, the number of co-authors per document is computed as 3.42. From the plot depicting annual growth of the journals under Figure.1, it can be inferred that the publication of the papers on the domain of sustainability of paper and pulp industry has picked up pace from 2008 onwards with focal publications happening only recently from 2018 onwards. Though the exponential growth visible during the recent years can be attributed to the spurt in publication of journal articles during and after COVID-19 Pandemic in general, but the fact that the sharp growth of the publications concerning the subject of sustainability and recycling in paper and pulp industry is visible from 2018 onwards and that the publication growth rate only on the subject of study has touched 12.0% is indicative of the relevance of the issues pertaining to sustainability in paper and pulp industry has found recently.
