Solid Waste Management and Recycling
Staff
Research Topics
To achieve Sustainable Development Goals, it is indispensable to promote citizens behavior modification and drive social transformation along the lines with 3R hierarchy which means Reduce as the 1st priority followed by Reuse and Recycle. Our laboratory aims to support science-based/data-driven decision making in MSW management planning, establish good practices on 3Rs, and expand their actual practices. Our main research fields are Japan and Vietnam. The research topics include Interrelationship among 3R behavior, attitude, and lifestyle; Effect prediction on 3R policies by Bayesian statistics methods; Behavior modification on 3Rs and effect measurement; Promotion of returnable glass bottles with Carbon Footprint Ecolabel indication on GHG mitigation effect by the repeated use; Effect analysis on point system for promoting return behavior of glass bottles; Supply-demand matching on food loss from business sectors; GPS/GIS application on waste collection and transport; Development of decision support tool on MSW management Planning.
Regional waste material recycling towards low carbon society
|
Sanitary waste treatment is a fundamental in solidwaste management, moreover, it is required that “fromwaste to material” and “from waste to energy” to mitigategreen house gases emission. Solid waste processes, suchas waste separation at source, segregated waste collection,optimal waste transportation, material and energy recoverytreatment, and safe landfill disposal, should be combinedappropriately 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 wasteshould be more utilized in a sound material-cycle society. Byconsidering characteristics of various kinds of solid waste generatedin our campus, such as kitchen waste, mowed grass,dead leaves, pruned branches, agriculture waste, animal dungin different seasons, our laboratory researches on effectivebiomass waste recycling methods. |

Development of a disaster waste management training system
|
Japan is exposed by many risks of natural disasterssuch as earthquake, land sliding, tsunami, flooding and so on.Once a big natural disaster comes like the Great East JapanEarthquake, a huge amount of disaster waste generates in ashort period. In order to recover the town from the damagespeedy, initial countermeasure actions for disaster waste treatmentby 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. |

Study on anthropogenic mercury releases for the evaluation of the effectiveness of the Minamata Convention on Mercury
|
The combination of anthropogenic activities and long-term atmospheric transport has resulted in a sustained increase in global mercury concentrations in air, in water and on land. The Minamata Convention on Mercury (MCM), is a global treaty with the goal of protecting human health and the environment from anthropogenic releases of mercury. This study aimed to quantify the mercury inputs and outputs in China in 2016–2019 according to source category and investigate the effect of scenario/technology transformation required by the MCM on the subsequent distribution of mercury among environmental and intermediate reservoirs. This is the first attempt to provide a systematic evaluation of the validity of the MCM. As the MCM moves into the implementation phase, further information from scientific data and studies is critically needed to support decision-making and management. The results of this study can provide such information, facilitating the creation of strategic management policies for mercury as the MCM is implemented. |
