Resumo: | Every day expressive amounts of coffee grounds waste generated during making the coffee beverage are produced worldwide. The aim of this work was to investigate the valorization potential of the coffee grounds waste as an alternative pore-forming agent to produce porous kaolin-based ceramic supports. For this purpose, kaolin-based ceramic support formulations containing up to 40 mass % of coffee grounds waste were pressed and fired at temperatures ranging from 1000 to 1200 ºC. The sintering behavior and technical properties (linear shrinkage, mass loss, apparent density, mechanical strength, and apparent porosity) have been investigated. The microstructural evolution has been accompanied by scanning electron microscopy (SEM) and 3D-confocal microscopy. The obtained results demonstrated that the coffee grounds waste could serve as a very effective pore-forming agent to produce kaolin-based ceramic support with highly porous structures. Such ceramic supports incorporated with coffee grounds waste exhibited values of apparent porosity within the range of 41.87 % to 70.96 %. This results suggests that the coffee grounds waste, in the range of 10 - 40 mass %, could be a highly promising renewable porogenic material to be valorized to produce low-cost kaolin-based ceramic support with good porosity properties. This new approach could be an innovative alternative for the sustainable use of coffee grounds waste. |

O objetivo deste trabalho foi investigar o potencial de valorização do resíduo borra de café como agente formador de poro alternativo para produzir suportes cerâmicos porosos à base de caulim. Para tanto, formulações de suportes cerâmicos à base de caulim contendo até 40 % em massa de resíduo borra de café foram prensadas e queimadas em temperaturas variando de 1000 a 1200 ºC. O comportamento de sinterização e as propriedades técnicas (retração linear, perda de massa, densidade aparente, resistência mecânica e porosidade aparente) foram investigados. A evolução microestrutural foi acompanhada por microscopia eletrônica de varredura (MEV) e microscopia confocal-3D. Os resultados obtidos demonstraram que o resíduo borra de café pode servir como um agente formador de poros muito eficaz para produzir suporte cerâmico à base de caulim com estruturas altamente porosas. Tais suportes cerâmicos incorporados com resíduo borra de café apresentaram valores de porosidade aparente na faixa de 41,87 % a 70,96 %. Este resultado sugere que o resíduo borra de café, na faixa de 10 – 40 % em massa, pode ser um material porogênico renovável altamente promissor a ser valorizado para produzir suporte cerâmico à base de caulim de baixo custo com boas propriedades de porosidade. Esta nova abordagem pode ser uma alternativa inovadora para o uso sustentável do resíduo borra de café.Todos los días se producen en todo el mundo cantidades expresivas de residuo poso de café generados durante la preparación de la bebida de café. El objetivo de este trabajo fue investigar el potencial de valorización de residuo de poso de café como agente formador de poro alternativo para producir soportes cerámicos porosos a base de caolín. Por lo tanto, las formulaciones de soportes cerámicos a base de caolín que contenían hasta un 40 % en masa de residuo de poso de café fueran prensadas y cocidas a temperaturas que oscilaron entre 1000 y 1200 ºC. Se investigaron el comportamiento de sinterización y las propiedades técnicas (contracción lineal, pérdida de masa, densidad aparente, resistencia mecánica y porosidad aparente). La evolución microestructural se siguió mediante microscopía electrónica de barrido (SEM) y microscopía confocal-3D. Los resultados obtenidos demostraron que el residuo de poso de café puede servir como un agente formador de poros muy efectivo para producir soportes cerámicos a base de caolín con estructuras altamente porosas.
