“…3a). This colour could result from residual carbon compounds that require a higher temperature or longer time to completely burn the straw samples (Wattanasiriwech et al 2010). The combustion of ash samples at 700 °C resulted in a grey colour, and they were easy to remove.…”

The thermal conversion of rice straw is an attractive option for recovering its energy, but the process requires exhaustive control because of ashrelated problems. Straw washing is one method of reducing ash-related problems and improving combustion behaviour. In this study, the ash of washed and unwashed rice straw samples was chemically characterized, tested using thermogravimetric analysis and environmental scanning electron microscopy (ESEM), and subjected to higher combustion temperatures in a muffle furnace. Results showed that silicon was the most important component in the ash. Furthermore, a reduction in undesirable inorganic compounds related to ash problems, such as chlorine and potassium, was achieved by washing the straw samples. This practice could improve thermal behaviour and decrease the sintering formation of ash.

“…As the pH of sodium acetate buffer was 4.8, theoretically all the silica in substrate could be retained in the residue after enzymatic hydrolysis. Some researches (Minu et al, 2012;Wattanasiriwech et al, 2010) reported that high purity silica nanoparticles could be produced from the hydrolyzed residue by chemical extraction methods or burning directly. This silica product has high surface area and amorphous structure for many industrial applications.…”

“…Natural silica, particularly those found in agricultural waste, can be used as an alternative source to replace the commercial silica precursors. Rice husk (Della et al, 2002;Liu et al, 2010;Athinarayanan et al, 2014), rice straw (Zaky et al, 2008;Wattanasiriwech et al, 2010), corn cob and bagasse (Usman et al, 2014;Vaibhav et al, 2014) is an agricultural waste as a source of silica which has been researched and transformed into more valuable products.…”

Silica is the most abundant components in the earth's crust and is made by way of synthesis for use in the application of technology. Silica are generally found commercially as alkoxysilane compounds (i.e such as tetraethylorthosilicate (TEOS), sodium silicate, and tetramethylorthosilicat). However, these compounds can have a negative impact on health. Thus, further approaches to find the source of silica that is safer, cheaper, and more environmentally friendly is inevitable. However, not all summary journals are thoroughly discussed the silica sources. Further, method of isolation and application of the silica from agricultural waste is limited. This paper reported studied several sources of silica derived from agricultural waste, such as rice husk, rice straw, corn cobs, and bagasse. In addition, this paper discussed also about the method of isolation of silica from agricultural waste, and its application as a catalyst.
