Levantamento bibliográfico sobre a inserção de combustíveis derivados de resíduos (CDR) na indústria cimenteira

Abstract

With the global increase of waste production, it becomes of great importance to develop the techniques of waste management and the ability to give the proper destination to these wastes to mitigate the environmental, social, and economic impact. Many ways can be adopted to deal with the municipal solid waste management, but the focus of this work is on the increased interest in the transformation of this type of waste into fuel for the cement industry. The objective of this study is to do bibliographical research about the insertion of fuel derived from residue (RDF) in the cement industry. For this, papers published in the SCOPUS database were analyzed while also analyzing Brazilian legislation, normative and resolutions. The results showed that in Brazil there is a favorable condition to produce RDF as there is a demand for energy by the industry of cement installed in the country. It was highlighted how much the step of producing the cement-clinker is responsible for higher carbon dioxide emissions and demands a high energy consumption, for these reasons it must receive attention to the development of actions to reduce negative environmental impacts. It was showed that the positive environmental impacts with the use of RDF instead of fuel derived from fossil fuels contributes to lower emissions of greenhouse gases, the operating costs of landfilling, to the technological, social, and economic development with the transformation of waste into a fuel with valuable energy use potential, and the enhancement on the waste treatment of municipal solid wastes. It was also perceived that the use of RDF for coprocessing show few negative environmental impacts, provided that a proper treatment and distribution of the wastes has been done before transformation of these into a fuel and subsequentially an effective control of the pollutant emission it’s also done. On the evaluation of the social and economic impacts with the development of a project to produce RDF it surges the creation of a new economic sector done either by public or private agents on the installed location of this plant, these project which can also apply sustainable development goals developed by the United Nations Organization, has profitable viability accompanied with relevant economic and social gains. In this study, it was evident, by the bibliographic research done, that the positive impacts stand out over the negative impacts with the use of RDF for coprocessing if the proper measures and surveillance for pollutants is done.
