“…Other positive aspect was the heating value, exceeding 18 MJ kg −1 , very similar value compared to those reported by Lopes Grotto et al [ 39 ] for rice husk from two types of genetically improved rice. Other authors, such as Su et al [ 3 ] reported an HHV value of slightly more than 15 kJ kg −1 .…”

“…The main waste that is generated is the husk that covers the grains of the rice. This by-product does not have an application in the elaboration of concentrated feed for animals due to its high silica content (SiO 2 ) [ 3 ], which significantly reduces its digestibility [ 4 ]. Due to its physical-chemical constitution, rice husks also represent a waste of very difficult biodegradation.…”

“…Some authors have studied the thermal characterization of rice husks and their behavior during combustion through several techniques [ 7 , 8 , 9 ]. On the other hand, other thermal processes, such as the pyrolysis of this by-product, have been studied by other researchers [ 3 , 10 , 11 ]. Gasification processes as a method for thermal use of rice husks was also investigated [ 12 , 13 , 14 ].…”

Rice husks are a by-product that is generated in large quantities in Spain. However, they are not used efficiently. One of their possible applications is its thermal use in power generation equipment. For that purpose, it is important to know the characteristics of rice husks and their thermal behavior, as well as their possible pollutant emission to the atmosphere with respect to its thermal use as a biofuel. In this work, the thermal characteristics of rice husks and their thermal behavior were studied by using thermogravimetry and mass spectroscopy for two different atmospheres (oxidizing and inert). This way, the thermal profiles and the main characteristics were studied, as well as the emission of possible pollutants to the atmosphere, such as CO2, CH4, NO2, NH3, SO2, and H2S. Moreover, three different methods (FWO, KAS, and Starink) were used to carry out a thermal analysis, in order to obtain the main thermal parameters such as activation energy. The results of the analysis predicted that rice husks could be used as biofuel in industrial thermal equipment based on its acceptable calorific value, good thermal characteristics, and low gas emissions both in oxidizing and inert atmosphere (although they have a high ash content).

Recently, the glycolipids biosurfactant materials have widely been utilized for many industrial applications due to their feasible surface activity, biodegradable as well as eco-friendly nature. Even though many of the earlier studies have been reported on such kind of surfactants, in this study we focused on porous rocks-like Fe 2 O 3 /C composites, which were magnificently synthesized from a novel tropical fruit biomass, using a glycolipid biosurfactant with high specific surface area of about 466.9 m 2 /g via a biofunctional single-step thermochemical method. They could be applied as an adsorbent to adsorb the pharmaceutical pollutants mainly, DCF from aqueous solution. Moreover, the highest adsorption capacity for DCF could be achieved, which is of about 77.51 mg/g. Furthermore, as-prepared glycolipid functionalized Fe 2 O 3 /C composites were used as electrode materials for high-performance supercapacitors.Galvanostatic charge-discharge results showed that the Fe 2 O 3 /C modified electrode possesses a specific capacitance of about 374 F/g with a current density of 0.2 A/g and it has retained 84% of capacitance, even after 3000 cycles.

“…Recentemente, pesquisadores demostraram meios para aplicar as cinzas de casca de arroz, como utilização na produção de carvão ativado, purificação de água e também como biofertilizante. Todavia, a superfície dura de sílica traz muitos problemas em relação ao uso eficiente da casca de arroz, já que, impede a decomposição de bactérias, diminui a densidade de energia e o valor da utilidade via conversão termoquímica ou bioquímica (SU et al, 2020;HUZIR et al, 2019).…”

RESUMOO ramo industrial cresce desenfreadamente, assim como a problemática referente a destinação dos resíduos agroindustriais, é fundamental obter meios para empregá-los. Aliando este inconveniente a outro problema ambiental, que é o tratamento das águas de captação e o tratamento de efluentes, especialmente no que se refere aos metais presentes, surge a técnica de adsorção. Trata-se de um método em que as moléculas presentes na fase líquida, quando em contado direto com a fase sólida, ficam retidas em sua superfície. Neste contexto, o objetivo do trabalho foi à obtenção de uma cinza de casca de arroz para adsorção, promovendo Brazilian Journal of DevelopmentBraz. a remoção de minerais alcalinos no tratamento de água. A cinza foi elaborada utilizando casca de arroz, que passou por tratamento ácido (sulfúrico, nítrico e clorídrico), em diferentes diluições volumétricas com água (1:1, 1:3 e 1:5) e posterior calcinação. As soluções foram preparadas para simulação do efluente líquido, eluídas na coluna contendo a cinza de casca de arroz (CCA) tratada e calcinada, na sequência foram coletas para serem quantificadas por meio do espectrofotômetro de absorção atômica, para avaliar o teor de minerais residuais em cada uma das cinzas obtidas. A melhor condição para retirada do manganês, foi o tratamento com ácido nítrico, em todas as razões volumétricas, especialmente na 1:1. Para o zinco foi com tratamento utilizando ácido sulfúrico especialmente na razão de 1:1 e para o ferro foi com tratamento usando ácido sulfúrico novamente na razão volumétrica de 1:1, os resultados foram em sua maioria satisfatórios e convenientes, confirmando a viabilização do desenvolvimento da CCA para adsorção dos metais.Palavras-Chave: Casca de arroz, Espectrofotômetro de absorção atômica, Metais, Adsorção ABSTRACTThe industrial sector grows wildly, as well as the problem related to the destination of agroindustrial waste, it is essential to obtain the means to use it. Combining this inconvenience with another environmental problem, which is the treatment of catchment waters and the treatment of effluents, especially with regard to the metals present, the adsorption technique appears. It is a method in which the molecules present in the liquid phase, when in direct contact with the solid phase, are retained on its surface. In this context, the objective of the work was to obtain a rice husk ash for adsorption, promoting the removal of alkaline minerals in the water treatment. The ash was made using rice husk, which underwent acid treatment (sulfuric, nitric and hydrochloric), in different volumetric dilutions with water (1: 1, 1: 3 and 1: 5) and later calcination. The solutions were prepared for simulation of the liquid effluent, eluted in the column containing the treated and calcined rice husk ash (CCA), and then collected to be quantified by means of the atomic absorption spectrophotometer, to assess the residual mineral content in each of the ashes obtained. The best condition for removing manganese was the treatment with nitric acid, in al...
