Phosphorus recovery from municipal solid waste incineration fly ash.
The potential of phosphorus (P) recycling from municipal solid waste incineration (MSWI) residue is investigated. Vast and ever increasing amounts of incineration residues are produced worldwide; these are an environmental burden, but also a resource, as they are a major sink for the material flows of society. Due to strict environmental regulations, in combination with decreasing landfilling s...
متن کاملSynthesis of calcium phosphate hydrogel from waste incineration fly ash and its application to fuel cell.
Waste incineration fly ash was successfully recycled to calcium phosphate hydrogel, a type of fast proton conductor. The crystallized hydrogel from incineration fly ash had a lower electric conductivity and a lower crystallinity than that from calcium carbonate reagent. However, the difference in electric conductivity between these crystallized hydrogels decreases with temperature. This was due...
متن کاملCharacterization of Bottom Ash, Fly Ash, and Filter Cake Produced from Hazardous Waste Incineration
in this study, the chemical characterization of solid residues, i.e., bottom ash, fly ash, and filter cake, produced from the izmit hazardous and Clinical waste incineration Plant (izAyDAS) was investigated. the izAyDAS is located in the city of kocaeli in turkey and it has been in use since 1997. Several parameters were measured, including AoX, Cl-, CN-, So4 2and selected heavy metals includin...
متن کاملPerformance of fuel cell using calcium phosphate hydrogel membrane prepared from waste incineration fly ash and chicken bone powder.
Waste incineration fly ash and bone powder could be successfully recycled to calcium phosphate hydrogel, a type of fast proton conductor. The electric conductivity of the crystallized hydrogel from them was compared with that from calcium carbonate reagent. It was found that the conductivity of the hydrogel from bone powder is almost equal to that from calcium carbonate reagent, which is higher...
متن کاملSpeciation of copper in the incineration fly ash of a municipal solid waste.
The speciation of copper and zinc in the incineration fly ash of a municipal solid waste in Taiwan was investigated in the present work. By the least-squares fitted X-ray absorption near edge structural (XANES) spectroscopy, we found that CuCO3, CuOH2, and CuO (fractions of 0.09, 0.39 and 0.51, respectively) were the main copper species in the fly ash. Quantitative analysis of the extended X-ra...
