“…Inorganic ash of pellets from mixtures also decreased with increase in pine contents of mixtures. It was confirmed that inorganic ash of biomass pellets depended on the composition of mineral constituents in the source fuel [14]. The main ash-forming elements of biomass materials included Na, Mg, Si, Al, Fe, Ca, Na, K, Zn and Ti [15].…”

a b s t r a c tTo the best of our knowledge, there is the lack of sufficient information concerning bamboo pellets. In the preliminary research, bamboo pellets showed a low bulk density which could not meet requirement of Pellet Fuels Institute Standard Specification for Residential/Commercial Densified (PFI). To improve its bulk density, pellets were manufactured using mixtures of bamboo and pine particles and the properties were investigated. It was found that adding pine particles to bamboo particles was an effective way to improve bulk density of bamboo pellets. When adding 40% pine particles to bamboo particles, bulk density of pellets increased from 0.54 g/cm 3 to 0.60 g/cm 3 , meeting grade requirement of PFI utility.Furthermore, length, diameter and inorganic ash of pellets were also improved. Fine contents of pellets decreased from premium grade to utility grade according to PFI standard. Net calorific value also slightly decreased but it could meet the requirement of DIN 51731 (>17,500 J/g). The effect of this interaction on bulk density, inorganic ash, Net calorific value, combustion rate and heat release rate were significant. The results from this research will be very helpful to develop bamboo pellets and provide guidelines for further research.

“…Density indicates the physical quality of densified solid biofuels (Temmerman et al, 2006), reflecting the amount of accumulated energy (Quirino et al, 2004) and its variation to the biomass characteristics such as granulometry, moisture and lignin contents, and the compaction process such as the applied pressure (dimension and time) and temperature (Dick et al, 2007;Mahapatra et al, 2010), which can be controlled to enhance the production efficiency and improve the quality of the final product (Carone et al, 2011).…”

The aim of this study was to evaluate the effects of potassium and sodium fertilization (control: 4.5kmol.ha-1 of KCl and 4.5kmol.ha-1 of NaCl), and water regimes (100% and 63% rainfall with artificial exclusion) on wood and briquette density in Eucalyptus grandis trees at 5 years, and the application of X-ray densitometry on the quality of briquettes. Tree trunk samples were obtained to determine wood density, production and briquette density by X-ray densitometry and stereometric. The artificial exclusion of rainwater promoted an increase in wood density, and the fertilization treatments versus water availability did not affect the density of briquettes. The method used to determine the briquette density influenced the average values, with an increase of 12% in the X-ray densitometry to the stereometric.

“…In addition, the country lacks suitable technology, proper technical handling, and legal practices on management. Heavy metals such as Cr and Cl in the ash can cause environmental pollution and problems to the operating equipment; proper treatment methods are indispensable [1,13,14].…”

The rapid economic growth of Vietnam has increased the amount of coal ash waste during electricity generation from coal-fired thermal power plants. This waste is being dumped even though the capacity of dumping sites will not be sufficient in the future. Accordingly, Korean technologies of recycling ashes, modifying them into a valuable product, and fixing carbon dioxide via carbon mineralization, can be an alternative to dumping. In this study, we aimed to investigate the feasibility of deploying carbon mineralization technology to Vietnam while considering technological, legal, and network perspectives. The material properties of coal ash and the applicability of coal ash recycling technology were briefly investigated in Vietnam. Legislation has progressed, focusing on recycling coal ash as a building material, with supportive measures on investment and international cooperation. Meanwhile, a bilateral network between Vietnam and the Republic of Korea at the institutional and governmental levels strengthened the implementation of practical technology cooperation. In conclusion, we considered various perspectives in terms of the technology transfer of recycling coal ash. This technology transfer model can contribute to enhancing the possibility of successful technology cooperation for solving the environmental problems of coal ash.
