“…Furthermore, the use of dedicated energy plantations for bioenergy in Europe could produce indirect land use changes rising food prices in other countries. For these reasons, the use of crop residues as lignocellulosic feedstock for heat and electricity production can be considered as a techno-economic feasible option [18][19][20][21][22][23][24] that helps to accomplish previously mentioned objectives [16,25].…”

“…Many factors such as type and availability of biomass, socioeconomic conditions and end-user applications help determine the most suitable bioenergy conversion process for a certain region [10]. For potential implementation in Ghana, four technology pathways were initially investigated; bio-chemical processes included fermentation of rice residues for bioethanol production and Anaerobic Digestion (AD) for biogas production.…”

“…As mentioned previously, economic considerations are vital to the success of a technology. This is especially true for bioenergy projects because local conditions determine factors such as residue availability, transport conditions, electricity needs of the local population and available infrastructure for developing the power plant, therefore affecting electricity production costs [10].…”

“…Economic viability of rice straw and husk power plants have been analysed in-depth in countries such as India, China, Thailand and Vietnam which conclude that rice residue can be an economically attractive option to produce electricity [10,12,14,19]. In SSA, Fock et al conducted a pre-feasibility analysis for setting up a 5 MW rice straw combustion plant in Mali [20].…”

a b s t r a c tDeveloping countries, especially in Sub-Saharan Africa, face large challenges to achieve universal electrification. Using the case of Ghana, this study explores the role that rice residues can play to help developing countries meet their electrification needs. In Ghana, Levelised Electricity Costs (LEC) of a gridconnected 5 MWe straw combustion plant ranged between 11.6 and 13.0 UScents/kWh, based on region of implementation. Rice straw combustion is a viable grid-connected option in all regions, as the bioenergy Feed-in-Tariff is 29.5 UScents/kWh in Ghana. Residue supply cost contributes significantly (49 e54%) to LEC of rice straw combustion.LEC of husk gasification mini-grids ranged between 5 and 53 UScents/kWh for rural populations between 3000 and 250 people. Husk gasification mini-grids can be a suitable electrification solution for these un-electrified populations, as its LEC is lower than the average LEC of grid extension diesel minigrids and off-grid solar systems for remote communities in Ghana. Electricity produced from husk gasification has the potential to cater to 7% of the needs of un-electrified communities in Ghana. The methodology and analysis of this study can support policymakers of similar countries decide the economic feasibility of decentralised bioenergy solutions while forming national electrification plans.

“…However, most of the rice straws are burnt in the field causing significant environmental and health problems as well as serious traffic accidents in addition to the loss of valuable resource (Chou et al, 2009). Rice residues are abundantly available and renewable and can be used as an energy source in thermochemical conversion processes such as gasification and combustion (Yoon et al, 2012;Delivand et al, 2011) or in bioconversion processes for production of bioethanol (Karimi et al, 2006) and biogas (Teghammar et al, 2012). The ash produced from gasification and combustion processes can be used as a supplementary material in cement and ceramic manufacturing (Zain et al, 2011) and the spent material from bioconversion can be used as an animal feed (Bisaria et al, 1997).…”

Rice husk and straw are by-products of rice cultivation and processing industry and can be used as an energy source. Proper understanding of the physical properties of rice residues is necessary for utilizing them in thermochemical conversion processes such as gasification and combustion. The physical properties (moisture content, particle size, bulk density and porosity) of rice husks and straws obtained from three countries (Egypt, Cuba and China) were evaluated in this study. The moisture contents of rice husks and straws were in the ranges of 4.60-6.07% and 6.58-6.92%, respectively. For all rice varieties tested, the moisture content of the straws was higher than these of the husks. The particle sizes of rice husks and straws were in the ranges of 0.212-0.850 mm and 0-0.710 mm, respectively. All the rice husk varieties had a normal distribution of particle size around the main value of 0.6 mm while the particle size distribution for the rice straws showed a decreasing trend, the larger the particle size the higher was the weight percentage. The bulk density of rice husks and straws were in the ranges of 331.59-380.54 kg m -3 and 162. 03-194.48 kg m -3 , respectively. The bulk density values of rice straws were lower than those of rice husks. A negative linear relationship between the bulk density and the average particle size was observed for rice husks and straws. The porosity of rice husks and straws were in the ranges of 63.64-68.94% and 71.21-85.28%, respectively. A positive linear relationship between the porosity and the average particle size was observed for rice husks and straws. Also, a negative linear relationship between the porosity and the bulk density was observed. The results obtained from this study showed significant differences in the physical properties of the rice husks and straws collected from different countries (located in three different continents). These differences may be due to variations in climatic conditions, soil type, methods of cultivation and type of fertilizer used. The results also indicated that different parts of rice plant (straw and husk) had different physical properties. Also, significant differences were observed among rice varieties even though they were grown under the same climatic conditions using same soil type and cultivation method as in the case of the long and short grain rice variety of Egypt.
