Due to rapid growth in population and industrialization, some new technologies are made for waste utilization and cost reduction in industrial processing by using rice husk (lignocellulosic biomass) as a valued material. In this paper various industrial and domestic application of rice husk and rice husk ash are discussed. Rice husk act as adsorbent for removing heavy metals from wastewater. In...

This study was conducted to evaluate the properties of cement bonded particleboard made from rice husk and sawdust. Sawdust and rice husk fine boards were made using two ratios of cement and particles of 70:30 and 80:20, but rice husk coarse was made with a ratio of cement and particle of 80:20. The density of sawdust and rice husk fine boards in a ratio of cement and particles of 70:30 was 960...

In this study, adsorption of zinc onto the adsorbent (untreated rice husk and NaOH-treated rice husk) was examined. During the removal process, batch technique was used, and the effects of pH and contact time were investigated. Langmuir isotherm was applied in order to determine the efficiency of NaOH-treated rice husk used as an adsorbent. The zinc adsorption was fast, and equilibrium was atta...

extensive application of silica nanoparticles (snps) in various industrial products has led to the development of silica extraction methodologies out of various waste products. rice husk is an agricultural waste with a high content of amorphous silica. however, the presence of metal ion impurities and unburned carbon in the rice husk content may present an adverse effect on product color and pu...

BACKGROUND Benzene is one of the most hazardous organic pollutants in groundwater. The removal of benzene from water is very important from a health point of view and for environmental protection. In this study, benzene adsorption kinetics was investigated using phosphoric acid activated carbon, prepared from rice husk. RESULTS An initial rapid uptake of benzene was observed and became almost...

The present study was conducted to prepare dietary fiber rich chicken meat rolls and patties. The combination of two different sources of dietary fiber has been used viz. rice bran and psyllium husk. Three different levels of rice bran and psyllium husk viz. 10% rice bran and 2% psyllium husk, 10% rice bran and 4% psyllium husk and 10% rice bran and 6% psyllium husk were tried. The sensory char...

Ionic liquids that dissolve cellulose provide an option to pretreat lignocellulosic biomass. In this study, potential application of three ionic liquids in pretreating rice husk and their abilities in dissolving rice husk cellulose were investigated. The ionic liquids applied were 1-butyl-3methylimidazolium chloride ([BMIM]Cl), 1-ethyl-3-methylimidazolium acetate ([EMIM]OAc), and 1-ethyl-3-meth...

Three common pretreatment processes based on dilute sulfuric acid, dilute sodium hydroxide and heat treatment (autoclaving) followed by enzymatic hydrolysis were evaluated to provide comparative performance data. Among them, the best result was obtained when the pretreatment of rice husk was carried out with 3% of NaOH solution. The pretreatment of rice husk with NaOH substantially increased th...

Rice husk is produced in a massive amount worldwide as a byproduct of rice cultivation. Rice husk contains approximately 20 wt% of mesoporous SiO2. We produce mesoporous silicon (Si) by reducing the rice husk-originating SiO2 using a magnesio-milling process. Taking advantage of meso-porosity and large available quantity, we apply rice husk-originating Si to lithium ion battery anodes in a comp...

Pretreatment of rice husk by the Alkaline Peroxide Assisted Wet Air Oxidation (APAWAO) approach enhanced the enzymatic convertibility of cellulose in APAWAO-pretreated rice husk. The present work describes the structural changes in rice husk brought about by APAWAO pretreatment by means of Scanning Electron Microscopy (SEM). The SEM images illustrate the extensive loss of biomass integrity foll...
