The present study aims to analyze the scenario relating to Brazilian and international scientific publications that deal with the reuse of gypsum plaster, carrying out a bibliometric mapping in the electronic database Web of Science (WoS) covering a period of twenty years, before and after CONAMA Resolution No. 431/2011, starting in 2001 and ending in 2020. Data collection began through exploratory research, where words and expressions were collected in abstracts and keywords from scientific productions related to the topic to create word clouds. In order to identify the scope of the three words identified as translations for gypsum plaster, an initial search was carried out in order to understand their return in numbers; then, search terms were created for searches for the three translations of the word gypsum, and a search term containing them all. The article data was exported to EndNote web, where the articles were selected, and later, using the VOSViewer software, bibliometric mapping was carried out. The database search identified 150 articles, of which 54 contained information on the recycling of gypsum waste, with the participation of 163 authors from 24 countries, the most representative being Brazil, with 13 publications. In the end, there is a lack of publications related to the topic, and that, despite some works published in relevant journals, research related to gypsum waste ends up alienating researchers due to the lack of work that supports new research, since the reference theory is essential for defining research hypotheses.

The construction sector stands out for the exploitation of natural resources and for the production of residues that, in the vast majority, are improperly discarded in nature, generating serious negative consequences for the environment. Aiming to minimize the harm caused by the poor disposal of Construction and Demolition Waste - CDW, as well as to develop alternative ways to replace natural raw material by recycled waste, many studies have been carried out. Among the materials that have high recycling potential is gypsum, whose residues are already being used as a binder, additives in Portland cement, soil correction, among other forms of recycling. Therefore, this study aims to analyze Brazilian and international scientific publications dealing with the reuse of plaster in civil construction, performing a bibliometric mapping in the Web of Science electronic database. The mapping was carried out through exploratory research related to the reuse of gypsum waste in several scientific articles. Words and expressions that had the highest frequency of occurrence in published articles were collected. The search in the database resulted in 89 articles, of which 42 contained information on the recycling of gypsum waste in civil construction. The selected articles belong to authors from 19 countries, the most representative being Brazil, with 13 articles. Through the VOSviewer software, network maps were elaborated, through which it is demonstrated how authors and scientific institutions relate in relation to the recycling of plaster waste. The results of the articles studied here compose a portfolio through which effective methods of reusing this waste can be verified, thus facilitating the search by third parties for this type of information. What can help in the formulation of public mechanisms that help to improve solid waste management in Brazil, because, through the social network Instagram, this information will be made available in order to reach an audience that goes beyond academic borders.
