Municipal solid waste incineration (MSWI) fly ash contains toxic heavy metals. Therefore, metal immobilization such as chelate treatment is required before landfill disposal. MSWI fly ash is considered as homogeneous owing to fine particles. However, MSWI fly ash has complicated structure inside particle and their micro-characteristics are still uncertain. In addition, mineralogical characteristics of MSWI fly ash are changed dramatically owing to wetting during chelate treatment. Therefore, this study investigated heterogeneity of chelate-treated MSWI fly ash particles using by SEM-EDX individually and collectively. Line profile analysis showed that coefficient of variation (CV value) of major elements in MSWI fly ash particles are distributed widely. This means that major elements in individual MSWI fly ash particles are heterogeneous. Area analysis showed that weight-based elemental concentration of MSWI fly ash particle surfaces are also distributed widely. Surface elemental characteristics are also heterogeneous among fly ash particles. Therefore, these results suggest that micro-characteristics of MSWI fly ash particles might have non-negligible impacts on leaching behaviors of heavy metals.

The authors conducted a simulated landfill experiment of bottom ash samples from a
municipal solid waste incinerator using 23 combinations of flue gas and fly ash
treatment agents. The cost estimates of municipal solid waste management from
incineration to landfill were compared with reference to the analysis of the
leachate. As a result, thecombination of dolomite hydroxide and sodium bicarbonate for
flue gas treatment and inorganic phosphorus-based chelating agent for fly ash treatment was
found to be the least expensive as well as highly effective in stabilizing the final
disposal site at an early stage.

In order to confirm reduction of slaked lime by collected dust recirculated system, we tried the system at Kiryu Clean Center. Then we operated the system under 10ppm and 50ppm of HCl and SOx in exhaust gas.
As a result, we confirmed from 20% to 40% reduction of slaked lime by the system. Furthermore, we could operate the system for a long term under 10ppm of HCl and SOx.

Constantly used as a HCL removal in bag filter system by using pulse
jet system in the municipal waste incineration facility Ca(OH)2, said that
there is a necessity from the verification of the neutralization reaction
pathway, it has been used with an excess of it in front of bag filter inlet in
order to meet the emission regulations concentration.In this paper, to improve
reaction efficiency of Ca(OH)2 and HCL at dust layer on the filter by the
improvement of filtration operation, as well as filter specification, we
examined experimentally to reduce Ca(OH)2 usage, the following findings were
obtained.1.Higher cleaning efficiency of dust on the filter, lower HCL
concentration and Ca(OH)2 amount at the filter exit can be achieved.2.It is
possible to obtain high cleaning efficiency in small specification of the
filter diameter, reduction of HCL concentration can be achieved.3.By using
layered washable method against dust on the filter, it is possible to reduce
the HCL concentration than milled peeling method. It is presumed that the dust
remaining in the filter cloth is a factor of the reaction efficiency reduction.

Bentonite mixed soil (BMS) is widely used as landfill leachate barrier system. By local subsidence of the foundation ground, there is a risk that a crack is generated in BMS is deformed. Therefore, it is important to understand the changes in the water barrier capability due to local subsidence of BMS.
Therefore,we carried out an experiment that simulates the occurrence of local subsidence by the life-size BMS layer, and evaluated the behavior by using theelastic-plastic FEM analysis.

Large
scale seashore MSW landfill has much amount of inner leachate, so that long
term management is required to stabilize a quality of the inner leachate. Even
if the inner leachate is positively collected, it will take decades for
leachate (discharged leachate) to satisfy the discharged water criteria. Land
use after closure of the seashore landfill is desired since it is located
around seaboard development region. We proposed a new methodology to establish
both environmental preservation and high-level usage of the land, by installing
both adequate thick final cover for infrastructure development and layered
drainage system for enhancing early stabilization of the leachate.

Watering is important for sound operation and maintenance in closed system disposal facilities (CSDFs). The Landfill Systems & Technologies Research Association of Japan (NPO/LSA) has a plan to publish a guideline of watering in CSDFs to improve design and oeration of watering for ealry waste stabilization. This study reports results of questionnaire survey for owners of CSDFs. The final goal of this study is to analyze actual data related to watering and to improve design and operation of watering in CSDFs
