Financial viabilities of husk-fueled steam engines as an energy-saving technology in Thai rice mills

Global Potential of Rice Husk as a Renewable Feedstock for Ethanol Biofuel Production

“…This presents an attractive opportunity to utilise such waste material for further processing particularly for the conversion into bioethanol. Typically about 50% of the husk produced in a rice mill is burnt onsite to produce steam to drive the mechanical milling machinery [21]. The remainder is sold to other industries primarily to the silica-based industries and put to use in building materials or as fertiliser.…”

Antioxidant property of solvent extract and acid/alkali hydrolysates from rice hulls

“…Since rice hull is inedible, it is used in various non-food applications. Research attempts were made to use the rice hull as fuel in the rice mills, brick kilns, boilers, furnace and power plants (Sookkumnerd, Ito, & Kito, 2005;Gidde & Jivani, 2007;Kumar, Mohanta, Kumar, & Prakash, 2012). The hull is reported as a source of xylitol, furfural, ethanol, acetic acid, lignosulphonic acids, bioethanol and silica (Gidde & Jivani, 2007;Matori & Haslinawati, 2009;Abbas & Ansumali, 2010;Kumar et al, 2013).…”

Quality optimization in briquettes made from rice milling by-products

“…Very few of the technologies that add value to rice husk have been tested in SSA. These include the use of rice husk as biofuel for the generation of heat and electricity (Sookkumnerd et al, 2005;Goyal et al, 2008;Lim et al, 2012a), biosorption of heavy metals from single and mixed metal solutions (Krishnani et al, 2008;El-Shafey, 2010), vermicomposting for the production of organic fertilizer (Lim et al, 2012b), as animal feed after physical, chemical, or biological treatment (Vadiveloo et al, 2009), and as a support for solid-state fermentation (Kapilan and Arasaratnam, 2011). Rice husk ash (RHA), a product of rice-husk combustion, is useful as a material for building and construction (Khan et al, 2012;Yuzer et al, 2013), glass ceramic tiles and whiteware (Prasad et al, 2001;Andreola et al, 2013), reinforcement of aluminum alloy (Saravanan and Senthil Kumar, 2013), production of silica powder, activated carbon, and carbon-silica composite (Kumagai and Sasaki, 2009;An et al, 2011).…”
