“…3b, which exhibited the presence of potassium, mainly in the forms of arcanite (K2SO4) and sylvite (KCl), and the presence of silica, in the form of quartz (SiO2), as the major components in RSA. After investigating sunflower husk ash (SHA) as a raw material for ceramic products, Quaranta et al (2011) demonstrated that the elements Si, K, Ca, and Mg were highly beneficial for the production of dense bodies used in traditional ceramic industries. Because the elemental composition of RSA was similar to that of SHA, RSA with relatively high contents of SiO2 (73.26%), K2O (13.46%), CaO (4.46%), and MgO (2.14%) could be used as a precursor for ceramic products in the construction industry.…”

The thermogravimetric characterization and gas emission properties during the pyrolysis of rice husk (RH) and rice straw (RS) were compared, and the properties of waste rice husk ash (RHA) and rice straw ash (RSA) from the combustion process were investigated. The results showed that the pyrolysis of RH and RS followed a four-step mechanism. Comparing the emission properties of small molecule bio-syngas in the pyrolysis of these two biomass wastes implied that RS was more suitable for use as feedstock for thermochemical conversion. Chemical and phase analysis results indicated that the RSA was rich in K, Ca, and P and had good potential for use as a soil amendment or as a material for silicate ceramics. The RHA was rich in SiO2 and could be an ideal silica source for silicon compound preparation or a pozzolan source for blended cement concrete production. Morphology analysis on the ash samples revealed that the high content of alkali metals may cause the higher agglomeration tendency of RSA with respect to RHA. The contrast in pore properties of biomass char wastes isolated from the ashes indicated that the char wastes recovered from RHA would be better used as a low-cost precursor in activated carbon production.

“…There have been numerous studies on the physicochemical properties of different biomass ashes, such as herbaceous biomass ash (Du et al 2014), bagasse fly ash Umamaheswaran and Batra 2008), capsicum stalk ash and cotton stalk ash (Niu et al 2010a), seaweed biomass ash (Wang et al 2008), cashew nut ash (Ogundiran et al 2011), wheat hull ash (Terzioglu et al 2013), peanut hull ash (Liao et al 2011), woody biomass ash (Skrifvars et al 2004;Ban and Ramli 2011), sunflower husk ash (Quaranta et al 2011), corn straw ash and bamboo ash (Fang and Jia 2012), etc. The physical and chemical properties of different biomass ashes are quite different.…”

Three typical biomass fuels-rice husk, rice straw, and corn cobs-were combusted to understand the effects of ashing temperature on ash fouling and slagging characteristics. The ashes generated from combustion at 600 °C and 815 °C were characterized thoroughly with regard to their chemical composition. The systematic slagging/fouling indices of biomass were used to study the effects of ashing temperature on ash fouling and slagging propensities. The results showed that ashing temperature had a remarkable influence on ash composition, particle size distribution, ash morphology, ash fusibility, and thermal properties. Increased ashing temperature resulted in the expansion of ash particles together with the volatilization of alkali metals in the form of inorganic salts. Morphology analysis indicated that high ashing temperatures promoted biomass ash slagging. Ash fusion points increased at elevated ashing temperatures, while the ash content decreased. As a result of the volatilization and decomposition of biomass ash, a four-step mechanism of weight loss was clearly identified by thermal analysis. All prepared biomass ashes resulted in slagging and fouling problems at different levels during the thermochemical conversion of biomass.

“…Paleckiene et al (2012) in the study they conducted in order to determine the physical and chemical properties of the fertilizer obtained by adding various additives (sugar factory lime, molasses, urea formaldehyde resin) to the ash obtained from sunflower residues found that as a result of turning sunflower waste ash and sugar factory lime mix into granules, a fertilizer containing 0.08% N, 5.94% P 2 O 5 , 12.97% K 2 O, 24.27% CaO, 10.0% MgO, 0.03% Na 2 O, 0.27% Fe, 0.02% Cu, 0.01% Zn, 0.04% Mn and 0.06% Mo and marketable appropriate parameters could be produced. Quaranta et al (2011) in their study of using ash obtained by burning sunflower husks in the production of ceramics or its re-use as a soil additive, found 15.6% Mg, 7.9% Ca, 4.8% P and 4.6% K in the content of sunflower husk ash. In our country, plant residues are used to meet the plant nutrients needed for agricultural production and to minimize the input costs.…”

Since plants need various plant nutrients during their development process, these needs are met with synthetic and chemicals inputs. This increases the input cost considerably. However, such problems can be eliminated thanks to the inputs obtained from completely natural plant wastes. Ash obtained from sunflower plant wastes, especially those used as fuel, has the potential to be an important natural fertilizer with plant nutrient elements in its content. In this study, it was aimed to determine some plant nutrients (B, Mg, P, K) found in the ashes obtained from burning of different variety (Coral, Pioneer63F73, PioneerP64LL05, Pioneer64LC108, Goldsun, Şems, Aga1301, Duna, Bosfora ve PioneerPR64G46) of sunflower plant wastes. As a result of the study, the highest B and Mg content was obtained from Pioneer PR64G46, P and Ca content from Pioneer P64LL05 and K content from Pioneer 64LC108. Observations show that the ash of the sunflower wastes has a very high content of phosphorus and potassium, and that these ashes can be used as fertilizers, especially in phosphorous and potassium-poor soils.Öz: Bitkiler gelişim süreçleri boyunca çeşitli bitki besin elementlerine ihtiyaç duyduklarından bu ihtiyaçları sentetik ve kimyasallar girdiler ile giderilmektedir. Bu da girdi maliyetini oldukça arttırmaktadır. Hâlbuki tamamen doğal bitki atıklarından elde edilen girdiler sayesinde bu tür sorunlar ortadan kalkacaktır. Özellikle yakacak olarak kullanılan ayçiçeği bitki atıklarından elde edilen kül, içeriğinde bulunan bitki besin elementleri ile önemli bir doğal gübre olma potansiyeline sahiptir. Bu çalışmada, farklı çeşitlere ait (Coral, Pioneer63F73, PioneerP64LL05, Pioneer64LC108, Goldsun, Şems, Aga1301, Duna, Bosfora ve PioneerPR64G46) ayçiçeği bitki atıklarının yanmasından elde edilen küllerinde bulunan bazı besin elementlerinin (B, Mg, P, K ve Ca) belirlenmesi amaçlanmıştır. Yapılan çalışma sonucunda, en yüksek B, Mg içeriği PioneerPR64G46 çeşidinden, P, Ca içeriği Pioneer P64LL05 çeşidinden ve K içeriği Pioneer64LC108 çeşidinden elde edilmiştir. Yapılan gözlemde, ayçiçeği atıklarının küllerinde oldukça yüksek fosfor ve potasyum içeriğinin mevcut olduğu, özellikle fosfor ve potasyumca fakir topraklarda gübre olarak kullanılabileceği öngörülmektedir.
