1. VISUALIZATION ANALYSIS OF LOCATION AND TREATMENT STATE OF INDUSTRIAL SOLID WASTE USING GIS Shinya Suzuki, Fumiaki Hirano, and Yasushi Matsufuji Department of Civil Engineering, Fukuoka Univeristy ssuzuki@fukuoka-u.ac.jp 8-19-1, Nanakuma, Johnan-ku, Fukuoka, 814-0180, JapanE-mail: ssuzuki@fukuoka-u.ac.jp 1. Introduction 2. Materials and Methods 3. Results and Discussions 4. Conclustions 3.1 Generation state of each kind of waste 3.2 Comparison between the treatment capacity and the actual treatment results 3.3 Treatment process in each treatment phase Municipal waste (50 Mt/year) Business waste Proper solid waste managemet ! but, no body knows actual treatment and landfill conditions Because, Each company and factory Waste service companies Which facilities? - Intermediate treatment(17,381) incineration, crush, drying, …. - Landfill site (2,717) How? - Any possibility to illegal dumping? -bottom ash -sludge -oil ……… Geographic Information System ◆ to establish an integrated industrial waste management system by using “Geographic Information System” location movement ◆ to analyze characteristics of location of treated facilities for understanding of waste movement process by comparing difference of waste construction waste ◆ to analyze actual condition of construction waste Database based on “ Annual Report ” ◆ Total amount of waste treated Small number of specific businesses have a great influence →Waste service companies in other prefectures Fig. 1 Flow of this study Fig. 2 Location of treatment facilities Table 1 Characteristics of analyzed data ◆ GIS? Data analysis easier by relational database -connection between multi tables based on common ID -connection between map and attribute information -enables data addition or modification freely -can divide “shared” with “separated” database -can minimize amount of data -can guarantee consistency of data Merit Fig. 3 Histogram on each category of waste from waste source Table 2 Comparison between treatment capacity and actual amount of waste treated in each treatment method Fig. 4 Treatment capacity and actual amount of waste treated in intermediate treatment facility for construction materials ◆ Planned treatment capacities are much higher than those of actual treatment results Especially in case of cement kilns, ◆ Some have 8,000 t/facility of capacity in larger sites, and enable to accept various kinds of and large amount of industrial waste Quality of criteria of recycled product is necessary to be taken into consideration for utilization of existing facilities ◆ Utilization of new technologies (melting, Refuse Derived Fuel (RDF) and Refuse Paper and Plastics Fuel (RPF) ): also considered to facilitate utilization of industrial waste.
