“…The water-soluble elements in various BAs have also been studied (see refs , , − , , , and − ). The reference data show (Table ) that the mobile elements (based on mean contents) leached from BAs and generated dominantly from woody and straw biomasses are mainly Cl, S, K, Na, Sr, Mn, and Ni and, to a lesser extent, Si, Li, Mo, Co, Cr, Cd, and Zn, and some Br, P, Al, Ba, Ca, Mg, Fe, Cu, Hg, Pb, Sb, and Se (see refs , , , , , − , and − ).…”

“…The impact of water leaching on biomass and BA properties has been studied to some extent. It was shown that such pretreatment of biomass reduces the ash yield and contents of water-soluble K, Na, and Cl bound in salts; increases the heating value; and modifies the ash chemistry and ash-forming processes. , The reference investigations reveal that the water-soluble components in biomass and BA may cause low ash-fusion temperatures; increased agglomeration, sintering, fouling, slagging, and corrosion; enhanced volatilization of hazardous compounds; increased fine particulate emissions; acidic to highly alkaline character of water leachates; contamination of air, water, soil, and plants by mobile toxic elements; deleterious effects in construction materials incorporating BA; and other technological and environmental problems and health risks. − It is commonly accepted in these studies that the concentration and behavior of elements such as K, Na, Cl, and S are mostly responsible for the above obstacles during biomass processing. However, it was recently highlighted that the high contents of specific water-soluble modes of occurrence of these and other elements may provoke the most important challenges during biomass and BA processing, and especially thermochemical conversion of solid biofuels. ,− In contrast, the water-soluble fraction of biomass and BA could also have some beneficial applications in the industry. , Hence, such mobile modes of element occurrence in biomass and BA require more detailed investigations.…”

An overview of the water-soluble fractions of biomass and biomass ash (BA) and their significance for solid biofuel application was conducted based on reference peer-reviewed data plus our own investigations. Characteristics such as fluid matter and moisture of biomass, composition, and properties of water-soluble fractions isolated from biomass and BA are considered, including fraction yield, content of water-soluble elements, phase-mineral composition, pH, and electrical conductivity. It was found that the water-soluble fraction of biomass and BA is highly enriched in Cl, S, K, Na, N, and P and some hazardous trace elements with unfavorable modes of element occurrences such as alkaline chlorides, sulfates, nitrates, carbonates, oxalates, and some oxyhydroxides, phosphates, and amorphous material. These compounds provoke the most critical technological (slagging, deposit formation, fouling, and corrosion) and environmental (fine particle partitioning, volatilization of hazardous air pollutant elements, and contamination of air, water, soil, and plant) challenges during the thermochemical conversion of biomass and BA processing. The reduction or immobilization of the undesirable water-soluble components in salt-tolerant biomass and BA can be achieved by feedstock selection, modification of harvesting and fertilization practices, natural or industrial water washing, fuel blending, and use of additives before processing. On the other hand, the water-soluble fraction leached from biomass and BA can be utilized for the recovery of some elements, synthesis of some minerals and production of soil amendments and different materials, whereas the water-soluble components in BA can contribute for capture and storage of atmospheric CO2.

“…Biomass charcoals were burned in a Yamato type FO100 furnace at 450˚C -550˚C to convert them to ashes. Care was taken to ensure that the ashing temperature did not exceed 600˚C, since biomass combustion at 600˚C -850˚C causes significant volatilization of potassium and fusion reactions between potassium salts and silica [19]. The produced ashes were cooled down and stored in a desiccator.…”

Biomass has the potential and benefits of being an alternative energy source to replace fossil fuels that exist today in Indonesia and other tropical countries. In addition, biomass has an abundant stock or supply. By assessing the feasibility of recovering potassium, it is hoped that more potassium resources and in future Indonesia will be dependent on imported fertilizers and increase the agricultural industry, which is the aims of this study. The best extraction result is using CH 3 COOH. Treatment of 1:10 solid-liquid ratio with the help of 1 mol/l CH 3 COOH was chosen as the best treatment because it is more economically efficient. Recovery of K with the help of tartaric acid and acetic acid resulted in a K recovery efficiency of around 94%. The optimal condition for the syngenite method is the addition of a magnesium dose of 5 mmol/l and at pH 11, the Ca: K ratio is 1:2.1 with 42% K. This can be a suggestion which method is more effective and efficient in recovery K.
