“…(iii) Cost-effective Biomass energy is cheaper compared to other forms of renewable energy generation. It has been reported that utilization of 70% of rice husk residues could contribute 1328 GWh electricity production annually, and the cost of per unit electricity generated using rice husk is 47.36 cents/kWh, compared to 55.22 cents/kWh of electricity generated by coal [47].…”

Potential of Rice Industry Biomass as a Renewable Energy Source

Fossil fuel depletion, along with its ever-increasing price and detrimental impact on the environment, has urged researchers to look for alternative renewable energy. Of all the options available, biomass presents a very reliable source due to its never-ending supply. As research on various biomasses has grown in recent years, waste from these biomasses has also increased, and it is now time to shift the focus to utilizing these wastes for energy. The current waste management system mainly focuses on open burning and soil incorporation as it is cost-effective; however, these affect the environment. There must be an alternative way, such as to use it for power generation. Rice straw and rice husk are examples of such potential biomass waste. Rice is the main food source for the world, mostly in Asian regions, as most people consume rice daily. This paper reviews factors that impact the implementation of rice-straw-based power plants. Ash content and moisture content are important properties that govern combustion, and these vary with location. Logistical improvements are required to reduce the transport cost of rice husk and rice straw, which is higher than the transportation cost of coal.

“…Bensten et al studied worldwide biowaste production from six main crops (sugar cane, soyabean, rice, maize, and barley) and estimated it to be around 3.7 Pg dry matter/year, with increment of 1.3 Pg dry matter/year [ 14 ]. In general, biowastes are used for the production of electricity energy by direct or indirect pyrolysis/gasification/combustion [ 15 ], resulting in ash production, harmful gas emission, and environmental pollution [ 16 ]. This study concentrates on the use of biowaste rice husk (BRH) as a source of the fiber part of biocomposites.…”

Experimental Study of Mechanical Properties of Polypropylene Random Copolymer and Rice-Husk-Based Biocomposite by Using Nanoindentation

et al. 2022

Nanoindentation is widely used to investigate the surface-mechanical properties of biocomposites. In this study, polypropylene random copolymer (PPRC) and biowaste rice husk (BRH) were used as the main raw materials, and glass-fiber-reinforced polypropylene and talc were also used with BRH to enhance the mechanical characterization of the biocomposites. The interfacial bonding between the polymer and the rice husk was increased by treating them with maleic anhydride and NaOH, respectively. The results obtained from the nanoindentation indicated that the plastic behavior of the biocomposites was prominent when untreated BRH was used and vice versa. The modulus and hardness of the biocomposite improved by 44.8% and 54.8% due to the neat PPRC, respectively. The tribological properties were studied based on the hardness-to-modulus ratio and it was found that BRH- and talc-based biocomposites were better than other samples in terms of low friction and wear rate. The creep measurements showed that untreated rice husk biocomposite exhibited high resistance to load deformation.

“…After all the samples inside the crucible were successfully melted, the crucible was removed with a platinum clamp and the samples are transferred to a stainless steel mold which has been preheated at 500 ∘ C and the samples then are annealed at 500 ∘ C for 5 hours while the leftover samples were transferred into the same stainless steel base which holds the mold and is annealed at the similar condition. Finally the samples were cut using a diamond blade cutter to a dimension of (1.0 × 2.0 × 0.3) cm 3 and later the samples were grinded using several grinding papers in the range of 320-1000 grit to ensure a perfect smooth surface for ultrasonic measurement. Samples thickness of (1.0 × 2.0 × 0.3) cm 3 is the optimum thickness because samples which are too thick or too thin may cause the decrease in ultrasonic wave intensity.…”

“…Rice cultivation in Malaysia has resulted in 400,000 metric tonnes of RH annually as it has been considered valueless and the main problem arises once it comes to the problem of getting rid of it [1]. RH is obtained as a worthless by-product as it cannot fetch a good price in the open market and most of the RH milling factories are massively influenced by this problem and disposing RH ethically will become unprofitable for them [2,3]. RH produced is generally discarded or burned and this has caused a serious threat to our mother earth and by developing new ways to reuse RH, it can be a useful by-product such as substitution for conventional silica in the glass industry [4,5].…”

Zinc silicate (ZnO-SiO 2 ) systems were fabricated using zinc oxide (ZnO) and white rice husk ash (WRHA) with compositions of (ZnO) x (WRHA) 1−x ( = 0.55, 0.60, 0.65, and 0.70 wt.%) was symbolized by S1, S2, S3, and S4, respectively. The ZnO-SiO 2 samples were fabricated by applying the melt-quench method and the physical and elastic properties of the samples were investigated. Physical properties used in this study are density and molar volume while the theoretical elastic moduli of the samples produced were obtained using direct calculation of theoretical model compared with the experimental elastic moduli obtained by acquiring ultrasonic velocities using ultrasonic pulse-echo technique. Values of experimental elastic moduli including longitudinal modulus ( ), shear modulus ( ), Young's modulus ( ), bulk modulus ( ), and Poisson's ratio ( ) were compared with theoretical model calculated using Rocherulle's model. All the configurations of the elastic moduli obtained experimentally match very well with the configuration from Rocherulle's model but Poisson's ratio obtained experimentally differs from the values of Poisson's ratio obtained through Rocherulle's model.
