In the local context, is clearly meet the need to enhance the sugarcane bagasse as biomass plant. Sugar cane bagasse is a waste coming from alcohol and sugar industries and available abundantly. This availability of sugarcane bagasse as raw material at low cost, combined with the...

The use of sugarcane bagasse minimizes the environmental impact and contributes to the creation of a new product with low density, good sound absorption capacity and can improve the acoustic conditions of buildings. The goal of this study aims to determine the intensity response ...

Abstract Glucose production from sugarcane bagasse was investigated. Sugarcane bagasse was pretreated by four different methods: combined acid and alkaline, combined hydrothermal and alkaline, alkaline, and peroxide pretreatment. The raw material and the solid fraction of the pre...

The present paper focuses on improving chromium (III) uptake capacity of sugarcane bagasse through its chemical modification with citric acid and/or sodium hydroxide. The chemical modifications were confirmed by infrared spectroscopy, with an evident peak observed at 1730 cm-1, a...

The valorization of agro-residues by biological routes is a key technology that contributes to the development of sustainable processes and the generation of value-added products. Sugarcane bagasse is an agro-residue generated by the sugar and alcohol industry in Brazil (186 mill...

In this work, cellulose from sugarcane bagasse was used for producing cellulose acetate aiming the production of asymmetric membranes. The obtained cellulose acetate presented degree of substitution of 2.49, characterized as a cellulose diacetate. Membranes produced from this mat...

Abstract The objective of this study was to evaluate the physical and mechanical properties of commercial panels produced with sugarcane bagasse to investigate the possibility of us for the production of furniture. We evaluated industrial MDP (Medium density particleboard) panels...

Considering the importance of drinking water and its effect on broiler performance, drinking water quality was studied using six different litter materials. The presence of coliform bacteria and Escherichia coli was investigated. The following litter materials were used in the tr...

The objective of this study was to evaluate the association of forage cactus with different fiber sources (elephant grass hay - EGH; corn straw - CS, hay of cassava shoots - HCS; fresh sugarcane bagasse - FSB; and hydrolyzed sugarcane bagasse - HSB) on the milk yield and composit...

Abstract Two experiments were carried out using loofa sponge and sugarcane bagasse as immobilization support. First a 2(5-2) design of experiments was realized with the following independent variables: sucrose concentration; pH; incubation time and agitation. Based on the best re...

The production of sugar, energy and ethanol from sugar cane is one of the most important activities of Brazil and generates a enormous quantity of bagasse which can be used to increase the ethanol production. In this sense, the study of sugarcane bagasse is a very important task,...

The objective of this work was to obtain experimental data of the kinetics of pretreatment with alkaline hydrogen peroxide and of the kinetics of the subsequent enzymatic hydrolysis of sugarcane bagasse. The pretreatment was performed in the conditions determined as optimal for t...

The capacity of activated carbons obtained from different raw materials, such as sugarcane bagasse, babassu (Orbygnia speciosa), and coconut (Cocus nucifera) shells, to remove residual chlorine is studied. The influence of particle size and time of contact between particles of ac...

This study aimed to evaluate how certain pretreatment conditions of sugarcane bagasse with dilute H2SO4 influence the size distribution of sugarcane bagasse, the chemical composition of solids pretreated and hemicellulosic hydrolysate, as well the enzymatic digestibility of pretr...

RESUMO O trabalho apresenta o potencial energético de blendas de bagaço de cana-de-açúcar e podas de mangueira e cajueiro. As amostras foram caracterizadas por meio da determinação do poder calorífico superior, densidade, análise imediata (umidade, cinzas, matéria volátil e carbo...

In this work, two catalytic systems combining Lewis and Brønsted acids (ZnCl2/HCl and AlCl3/HCl) were applied in a tetrahydrofuran (THF)/NaClaq biphasic system to produce furan compounds from plant polysaccharides. The following cellulosic matrices were applied for this purpose: ...

RESUMO A busca de novas alternativas para reutilizar resíduos é uma maneira de minimizar impactos ambientais promovendo práticas sustentáveis. Este trabalho analisou a viabilidade técnica da produção de briquetes a partir de resíduos de poda urbana e bagaço de cana-de-açúcar, tra...

This experiment was carried to evaluate the effect of forage cactus with different fiber sources (elephant grass hay [EGH], corn straw [CS], hay of cassava shoots [HCS], fresh sugarcane bagasse [FSB], and hydrolyzed sugarcane bagasse [HSB]) on intake, apparent digestibility and m...

ABSTRACT This work studied the enzymatic hydrolysis of sugarcane bagasse aiming at the production of glucose and xylose. The bagasse was subjected to two different pretreatments: combined acid and alkalinepretreatment and hydrogen peroxidepretreatment. The enzymatic hydrolysis wa...

An evaluation was made of the properties of sugarcane bagasse during the storage process for subsequent burning in a boiler. Samples of bagasse were collected over a period of 150 days from the Caeté sugar mill (MG) at various points of the stockpile soon after the sugarcane was ...
