■ Introduction to Research〓 Research Area : Solid Waste Management and Recycling
Regional waste material recycling towards low carbon
society: Sanitary waste treatment is a fundamental in solid waste management, moreover, it is required that “fromwaste to material” and “from waste to energy” to mitigate
green house gases emission. Solid waste processes, suchas waste separation at source, segregated waste collection,
optimal waste transportation, material and energy recovery
treatment, and safe landfill disposal, should be combined
appropriately so as to shorten the environmental burden.
Our laboratory studies on designing methods to establish asophisticated solid waste management that is suitable forsustainable regional society, specially in Asia.

Evaluation of the biomass waste recycling in university
campus: From view point of carbon neutral, biomass waste
should be more utilized in a sound material-cycle society. By
considering characteristics of various kinds of solid waste generated in our campus, such as kitchen waste, mowed grass,dead leaves, pruned branches, agriculture waste, animal dung
in different seasons, our laboratory researches on effective
biomass waste recycling methods.

Development of a disaster waste management training
system: Japan is exposed by many risks of natural disasters
such as earthquake, land sliding, tsunami, flooding and so on.
Once a big natural disaster comes like the Great East Japan
Earthquake, a huge amount of disaster waste generates in ashort period. In order to recover the town from the damage
speedy, initial countermeasure actions for disaster waste treatment by local government are quite important. Therefore, ourlaboratory is constructing a knowledge base of the actions andalso developing a training support system for the local government.

Modeling on waste generation and discharge

To support rational and effective decision making onmunicipal solid waste management toward sustainable
society, our laboratory aims to accumulate the scientific base by the following research activities:✓ Detail survey on municipal solid waste generation,
demographics, 3R behavior, pro-environmental
attitudes, lifestyle, and household expenditure inJapan and Vietnam✓ Exploring influence factors and Bayesian modelingof waste generation and 3R behavior✓ Political effect prediction on 3Rs and reliability verification✓ Accuracy improvement on sales prediction of fooditems by Deep Learning toward food loss reduction

promotion measures and 3R behavior

To establish and expand 3R good practices towardsustainable society, our laboratory tries some pilot
studies including 3R promotion and effect measurement as the following activities:✓ Experience-based activity for 3Rs in cooperation
