Abstract
Conducted study on disposed disaster wastes were scrutinized and achieved by The Japan Society of Waste Management Experts mainly, and geotechnical aspect of Japan Society of Engineering Geology or The Clay Science Society of Japan after 1995 South Hyogo Prefecture Earthquake from the environmental impacts as bloated garbage. In this paper, the authors indicated desirable risk management, as determined by the regional features considering with waste management in case of The Niigataken Chuetsu-oki Earthquake in 2007 based on reconnaissance investigation and questionnaire. Furthermore, we analyzed recyclable geotechnical material with our experiment, as reference to Tokyo Metropolitan Government. Sequential surveys resulted in reduction of waste amount due to the separated garbage collection system by residents in persistent, ultimately, ban for enormity dumping under cooperation between family or citizen, therefore environmental mitigation as to vulnerability from helm of wallow mixtured waste through field survey and enquête. In addtion to that, we mentioned heavy metals in huge wastes based on our monitoring results of coastal area in Niigata Prefecture, and overviewed geotechnical remedy.
