This might also be due to the compounding effect with authors researching on the above domain preferring JoCP over other journals for publication of their articles.

From the plot at Figure.4 below, it can be seen that the most discussed words as on 2022 are ‘paper and pulp industry’ and ‘sustainable development’. The ranking of the words at the first and second position of relevance is not surprising as the keywords were a part of the search criteria for selection of the articles. Yet, the sudden emergence of the concepts from 2020 onwards is an indication that academic discourse on sustainable pulp and paper industry is bustling under active mode. But, listing of the word “Recycling” at third position as on 2022 and seen to be dominating the word list from 1996 to 2020 in the present bibliographic pool of study implies that predominantly the focus of journal articles on pulp and paper industry from 1996 till 2020 revolved around recycling activities, which could be related to the effluents, the quintessential and the most toxic by-product of the process, though the discourse was been fairly consistent even till 2022, as is event from the trajectory of occurrence. Other words featuring in the list of top 10 prominent words as on 2022, in the order of relevance are ‘supply chains’, ‘forestry’, ‘paper’, ‘pulp’, ‘paper industry’, ‘pulp and paper industry’ and ‘supply chain management’ and all of these words were found to have been discussed in the academia from 2005-2006 onwards fairly consistently.
