Cenário da disposição do lodo de esgoto: uma revisão das publicações ocorridas no Brasil de 2004 a 2014

Resumo

The population growth, added to the urbanization and the economic development, are indubitable causes of the increasing generation of waste, and in Brazil, its mismanagement highlights difficulties as to inadequate disposal, informal collection and insufficiency regarding the public collection system. Sewage sludge, which is waste, refers to an inevitable product of the wastewater treatment, with its inadequate disposal being an existing problem all around the world. To the national scenario, there is a lack of official information concerning the sewage sludge disposal. However, many authors have been searching for alternative ways to utilize and reutilize those biosolids. The purpose of this research was to map, using the Mapping Study methodology, the main trends of the use and disposal of sewage sludge in Brazil, based upon the technical and scientific work published from 2004 to 2014. The electronic publications were searched for on the SciELO database, CAPES, and the Google Scholar website. According to the scientometric data analysis proposed by this study, Brazilian reality as for the disposal of sewage sludge is either the vegetable production or the restoration of degraded lands, present in 91,7% of the publications found, drawing attention to agricultural application (82,1%), especially the corn production (19,9%). However, even lessened in numbers, lines of research on the use of biosolids for production of ceramic artifacts, civil construction and energy generation (8,3%), have swimmingly come into view. The State of São Paulo is the largest federal unit with technical and scientific production in the research area, reaching 61.8% of all articles found.
