About the laboratory
Description
The current research subjects of our laboratory are as follows;
1. Thermal treatment of waste (reaction mechanism in incineration furnace and exhaust gas treatment process, improvement of flue gas treatment efficiency, and pretreatment of incineration residue (fly ash) for landfill to insolubilize hazardous heavy metals, etc.).
2. Final disposal (behavior of hazardous elements in landfill, reaction process of them, stabilization process of them, weathering test to investigate long-term behavior, and modeling, etc. ).
3. Radioactively contaminated waste generated by the Fukushima nuclear power plant accident (insolubilization of cesium contained in fly ash generated from treatment process of decontamination waste, analysis of Invasion depth of radioactive material into contaminated concrete),
4. Survey on environmental impacts caused by current measure of waste disposal in the Arctic local community.
Organization of research
(Master course student)
In first year, though student must take course work and focus on them, research for master thesis have to be initiated.
We have a laboratory seminar once in a week.
The rotation is set in the order of 2nd grade master course student, bachelor course student, 1st grade master course student, and staff.
So, 1st grade master course student must conduct presentation every 4 week.
The theme of master thesis is determined during first year as fast as possible.
The theme is selected among the themes related to the project that are going on.
In 2nd year, student devotes oneself to the research.
During 2nd year, presentation at domestic or international conference is obligation in our division.
(Doctor course student)
At present, we don't accept doctor course student other than the student who graduated our master course program.
Ongoing projects
1. 2020-2024：ArCS II: Arctic Challenge for Sustainability II, "Changes in the coastal environment in the Arctic and its social impact" (partaker)
2. 2020-2023：MEXT: "Quantitative evaluation of long-term change of contaminated reinforced concrete considering the actual site environment for achieving reasonable final disposal"(partaker)
3: 2019-2021：JSPS Grant-in-Aid for Scientific Research (B) "Insolubilization of heavy metals contained in fly ash by alkali feldspar and realization of final storage quality"
4. 2021: Collaborative study with private company, "Influence of the combustion condition on the characteristics of bottom ash"
5. Some other projects will be started from 2022, though they cannot be written here.
Current research themes of students are as follows; (B4: undergraduate, M2: 2nd grade master student)
- Elucidation of nitrogen oxide formation/reduction mechanism in the incineration furnace (B4)
- Reaction mechanism of Calcium hydrooxide and hydrogen chloride in the waste incineration flue gas treatment process (B4)
- Dry scrubbing of waste incineration flue gas using porous sodium carbonate produced by thermal vacuum treatment (M2)
- Influence of low air ratio in furnace on incineration residue characteristics (M2)
- Capturing harmful heavy metals contained in incineration fly ash by aluminosilicate (B4, M2)
- Improvement the capturing efficiency of Cesium by aluminosilicate using a rotary furnace (B4)
- Survey of the invasion depth of Cs and Sr in concrete waste generated from decommissioning of nuclear power plant (B4, M2)
- Waste Disposal and Global Warming Impacts in Arctic Local Communities (B4)
Enrolled students' research topics
The topic will be selected from the project being conducted or topic related to ongoing project.
Information for potential applicants
Applicants' background
Background in chemical engineering or environmental engineering is preferable because chemical analysis is always necessary for our research topic.
How to choose a research proposal topic?
Research topic closely related to the themes being conducted in our lab is preferable, otherwise it is difficult for us to guide research work.
