Following the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident caused by the 2011 Tōhoku earthquake and tsunami, radioactive caesium (r-Cs) was detected in the ash generated by municipal solid waste (MSW) incineration facilities in Fukushima Prefecture. This has led to concerns of r-Cs leaching and subsequent environmental contamination during recycling or landfill disposal. Therefore, it is crucial that the relevant authorities have a thorough understanding of r-Cs leaching behavior to establish suitable prevention methods. In this study, we collected r-Cs-contaminated fly and bottom ash (FA and BA) samples from five MSW incineration facilities in Fukushima Prefecture and conducted tests to clarify their basic physical properties and r-Cs leaching properties. We also examined the possibility of preventing r-Cs leaching by adding 5 wt% acid clay to the FA. FA had greater chloride content and r-Cs leaching rate than BA and was found to absorb moisture and deliquesce when stored under high-humidity conditions. However, the addition of acid clay effectively prevented r-Cs leaching upon contact with moisture. From the results, we propose some specific recommendations to counter the leaching of r-Cs from FA at MSW incineration facilities, which will limit r-Cs leaching during recycling or landfill processes.

Heavy metal capture experiments were carried out in a tube furnace to investigate the effect of different sorbents and Si-Al ratios on the capture of Zn, Cu, Pb, Cd and Cr during simulated MSW incineration. The incineration bottom ash was digested by aqua regia and HCl/HNO3/HF, then determined by ICP-AES. Experimental results indicate that HCl/HNO3/HF is more suitable for the digestion of incineration bottom ash than aqua regia; the volatilization capacities of the five metals during simulated MSW incineration at 1000°C follow the sequence of Pb > Cd > Cu > Cr > Zn; zeolite and limestone have a certain efficiency to capture Zn and Cr while kaolinite has no efficiency to capture all the five metals; the addition of kaolinite and zeolite can prevent the glass and brick powder from melting which can cause the package of heavy metals, but the addition of zeolite can promote Zn and Cr to form silicate, aluminate and aluminosilicate; the mixture of SiO2and Al2O3is in favor of the adsorption of Cd and Cr, but against the adsorption of Pb and Cu compared with single SiO2or Al2O3.

The presence and composition of ash in solid waste streams produced by the thermochemical processes can affect the further disposal or use of the waste. This study characterised the chemical species, mineralogy and trace element mobilisation in laboratory-produced ashes arising from different municipal solid waste (MSW) streams processed under reducing and oxidising atmospheres. The composition of cumulative ash samples produced under oxidising conditions was very similar to the composition of the industrial bottom ash samples produced during MSW incineration. We identified differences in mineral phase compositions and in some trace element concentrations of ashes produced under combustion and gasification conditions. Differences in concentrations of boron, barium, cadmium, chromium, copper, chlorine, molybdenum, antimony, lead, thorium and zinc in ashes associated with different MSW streams were also observed. On the basis of the concentrations of trace elements in ashes, we evaluated each MSW stream in terms of potential management strategies and use of the mineral matter remaining after combustion and gasification. Most of ashes produced from MSW can be at least classified as Class IV (secure) waste according to an Australian standard regulation guideline.

Incineration bottom ashes (IBA) are the main waste from municipal solid waste (MSW) incineration. In the Iberian countries (Portugal and Spain), MSW incineration with energy recovery (WtE) plays an important role in MSW management. IBA is highly produced and managed differently both between and within countries. This paper aims to provide a comprehensive overview of the management model of IBA using the Iberian Peninsula as a case study, addressing its properties, current management, incentives and difficulties in valorizing, and prospects. For this purpose, incineration plants of both countries were approached, and a broad literature review was conducted to gather information. About 10% and 41% of IBA have been landfilled in Portugal and Spain, respectively. Metals (mostly ferrous) from Portuguese (6% of IBA) and Spanish (9% of IBA) WtE plants are recycled. In Portugal, the remaining IBA (84%) has been temporarily stored (11%), applied to landfills as a substitute for soil in intermediate and final covers, construction of paths, accesses, and platforms (41%), or used in civil engineering work and road construction (48%). In Spain, the remaining IBA (50%) has been reused mainly as a secondary raw material in the construction and civil engineering fields (77%), while the rest has been temporarily stored (11%), applied in the conditioning of landfills (4%), alsoa secondary aggregate replacing natural materials. Both countries regulate IBA reuse outside landfills but consider different requirements and criteria. Nevertheless, there are both drivers and barriers to valorization. In the future, different IBA applications will likely continue to be developed, with the concern of protecting the environment. Growing confidence in IBA reuse following the publication of proper studies is expected. Globally, uniform legal frameworks among EU members with the same standards would likely lead to better IBA valorization.

The clay-based ceramic was produced by adding with the bottom ash from domestic municipal solid waste incinerator plant in Thailand. The amount of the ash up to 60 wt% was added. The samples were dry pressed and sintered at the temperature range between 1000 and 1125°C. The presence of quartz (SiO2), anorthite sodian (Ca,Na)(Si,Al)4O8, albite (Na(Si3Al)O8) and mullite (Al6Si2O13) was observed in the sample with the addition of the bottom ash. The physical and mechanical properties were also presented. The sintering temperature and the ash addition revealed the effect on the properties of the product.
