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.
