Most of waste related environmental issues have originated from the present social system of mass-production / mass-consumption / mass-disposal approach. Long-term sustainability is impossible as long as today's social system remains unchanged. In order to achieve the Material Cycles Oriented Society, we make studies on developing technologies and systems for waste recycling and proper treatment in the process of waste generation, recycling, treatment and disposal. Current research outline in the waste management is as follows;

1. Forecasting of property of waste and incinerated residue in the future
With future recycling promotion, the property of collected municipal solid waste and its incinerated residue seem to greatly change in the future. We aim to forecast these properties to propose the proper systems for treatment and disposal of incinerated residue.

2. Reduction of environmental loading in incinerated residue
In order to utilize the incinerated residue as recycled construction material, the research on its material property, long-term leachate under various environmental conditions and method to reduce environmental loading caused by incinerated residue are carrying out. As it is reported that about 40% of surface soil in Japan is derived from volcanic ash, the incineration residue, which is thought as artificial volcanic ash, from the waste incinerator furnace, which is seemed as an artificial volcano, might also be made into soil by soil formation factors. We focus on this stabilizing mechanism of incineration residue to develop the technology in which the environmental loading is reduced economically without input of large amount of energy.

3. Advanced landfilling method
Geodetically, the physically separated incineration residue can be used as more intensive material for construction. We are trying to develop the method, which promotes stabilization of landfill site and which enables advanced utilization of ultimate land, by improving landfilling method. This is more effective especially for sea reclamation in which the stabilization is retarded.

4. Application of remote sensing for waste management
For the proper management of large scale landfill sites in Asian countries covering Japan, China and Korea, this study aims to develop a new monitoring method using remote sensing data, which is obtained by both satellite and ground level remote sensing. Similarly, we are trying to apply satellite remote sensing to detect illegal waste dumping sites.

5. Evaluation and prediction of resource/energy consumption in Asian mega-cities
In Asian mega-cities such as Beijing and Shanghai, economies continue to shift toward mass-consumption, mass-disposal systems. This change is expected to have a major impact on the global environment. In this study, we aim to predict the future situation of resource and energy consumption in Asian mega-cities, and try to search for a viable pattern of sustainable consumption.
