A sustainable approach to the recycling of rice straw through pelletization and controlled burning

Influence of densification parameters on quality properties of rice straw pellets

“…The selection of a binder depends fundamentally on its cost and environmental friendliness [28,29]. Ewida et al [7] studied the effect of five bonding materials (starch, sodium silicates, latex, phenolFuel Processing Technology 138 (2015) [56][57][58][59][60][61][62][63][64] formaldehyde and molasses) on rice straw pellet strength, their results showing that starch is the best bonding material, in view of strength and combustion characteristics. Maize starch has been recommended as a better additive for power consumption per unit of pellet output, when compared to other additives [30,31], due to its lubricating ability [32].…”

“…Rice straw can be converted to energy by means of different techniques, such as direct combustion, gasification, pyrolysis, and anaerobic digestion [7]. The direct combustion of rice straw affords the advantage of comparatively high energy conversion efficiency, but it entails operating problems such as high ash content and sintering formation [8,9].…”

Reduction of Ash Sintering Precursor Components in Rice Straw by Water Washing

“…The combustion of rice straw to directly produce thermal energy not only saves energy, protects the environment, and reduces field-burning pollution; it also increases the income of farmers (Ewida et al 2006;Yu et al 2008). There are, however, some technical limitations involved in thermal conversion systems, such as high ash content, sintering, slag formation, and corrosion problems Baxter et al 1998;Fu et al 2009;Said et al 2013b).…”

“…Rice straw is one of the main agricultural residues in countries such as Egypt, Thailand, China, and especially Japan, where it comprises the largest amount of unused agricultural residue by far (Matsumura et al 2005;Delivand et al 2011;Liu et al 2011;Said et al 2013a). Its energy can be recovered directly through a combustion process, or it can be converted to a valuable energy product through indirect techniques such as gasification and biochemical conversion, after which the products can be burned (Ewida et al 2006).…”

Simulation of biomass gasification in downdraft gasifier for different biomass fuels using ASPEN PLUS

“…They developed a statistical correlation analysis of the hybrid energy system for a remote area in India. Ewida et al (2006) conducted both experimental and modeling studies with well-designed rice straw pellets in a fluidized bed. The model was used to analyze the effect of operational parameters on the pellet combustion and the characteristics including bed temperature, gas flow, and oxygen concentration.…”
