Resumo: The new concepts of Circular Economy (EC) and changes in the world energy matrix drive the consumption of biomass as an alternative source for energy production. In this context, eucalyptus (Eucalyptus) chips are a promising source of biomass. The burning of this biomass produces ash residue, which needs to be disposed of properly or recovered to reduce the environmental and economic impacts of this residue. This review article aims to discuss the valorization of industrial boiler biomass ash with a focus on the production of alkalizing agent. The recovery of this residue has taken place in different ways, with the use of alkalizing properties for soil correction as the most common within industrial practices of waste management. On the other hand, the solubilization of the oxides present in the ash and the use of this extract as an alkalizing agent in the treatment of water and effluents can be an alternative to conventional alkalizing agents. This would increase the possibilities of valuing the ash, reducing the negative impacts of energy generation processes. Studies and conditions for the production of alkalizing agent are not clear in the literature.

En este contexto, la astilla de eucalipto (Eucalyptus) es una fuente prometedora de biomasa. La quema de esta biomasa produce residuos de cenizas, que deben eliminarse adecuadamente o recuperarse para reducir los impactos ambientales y económicos de estos residuos. Este artículo de revisión tiene como objetivo discutir la valorización de cenizas de biomasa de calderas industriales con un enfoque en la producción de agente alcalinizante. La valorización de este residuo se ha realizado de diferentes formas, siendo el uso de propiedades alcalinizantes para la corrección de suelos la más habitual dentro de las prácticas industriales de gestión de residuos. Por otro lado, la solubilización de los óxidos presentes en las cenizas y el uso de este extracto como agente alcalinizante en el tratamiento de aguas y efluentes puede ser una alternativa a los alcalinizantes convencionales. Esto incrementaría las posibilidades de valorización de las cenizas, reduciendo los impactos negativos de los procesos de generación de energía. Los estudios y condiciones para la producción del agente alcalinizante aún no están claros en la literatura.Os novos conceitos de Economia Circular (EC) e as mudanças na matriz energética mundial impulsionam o consumo de biomassa como uma fonte alternativa para a produção de energia. Neste contexto, o cavaco de eucalipto (Eucalyptus) é uma fonte de biomassa promissora. A queima desta biomassa produz como resíduo as cinzas, que precisam ser dispostas adequadamente ou valorizadas para diminuir os impactos ambientais e econômicos deste resíduo. Este artigo de revisão tem como objetivo discutir a valorização das cinzas de biomassa de caldeira industrial com foco na produção de alcalinizante. A valorização deste resíduo tem se dado de diferentes formas, sendo o uso das propriedades alcalinizantes para a correção de solos como a mais comum dentro das práticas industriais de gerenciamento de resíduos. Por um outro lado, a solubilização dos óxidos presentes nas cinzas e a utilização deste extrato como alcalinizante no tratamento de águas e efluentes pode ser uma alternativa aos alcalinizantes convencionais. Isto aumentaria as possibilidades de valorização das cinzas, diminuindo os impactos negativos dos processos de geração de energia. Os estudos e as condições para a produção do alcalinizante ainda não estão claras na literatura.Research, Society and Development2022-07-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3131210.33448/rsd-v11i9.31312Research, Society and Development; Vol. 11 No. 9; e2711931312Research, Society and Development; Vol. 11 Núm. 9; e2711931312Research, Society and Development; v. 11 n. 9; e27119313122525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/31312/26885Copyright (c) 2022 Henrique Signor Backes; Marcelo Hemkemeier; Gabriela Dalmora; Sabrina Toninhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBackes, Henrique Signor Hemkemeier, Marcelo Dalmora, Gabriela Tonin, Sabrina 2022-07-21T12:36:16Zoai:ojs.pkp.sfu.ca:article/31312Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:47:42.065637Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
