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 , Nanakuma, Johnan-ku, Fukuoka, , Japan 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. Fig. 6 Visualization of flow on sludge in each treatment phase Fig. 7 Visualization of flow on construction materials in each treatment phase Fig. 8 Visualization of flow on plastics in each treatment phase Landfill (sludge) Landfill (construction material)Landfill (plastics) 2nd treatment (sludge) 1st treatment (sludge) 2nd treatment (construction material) 1st treatment (construction material) 2nd treatment (plastics) 1st treatment (plastics) 3.4 Flow analysis on each phase of treatment Fig. 5 Treatment process in each waste “Industrial waste” (400 Mt/year) General waste 2nd treatment ◆ 1st treatment Volume reduction, homogenization, separation ◆ 2nd treatment Change of properties, reproduction or stabilization Flow analysis on sludge ◆ 1st treatment - Transported from neighboring municipalities, especially from Fukuoka city ◆ 2nd treatment - Transported in great distance from such as Tokyo metropolitan area and Osaka area ◆ Landfill - Highest quantity of waste: transported from subway construction in Fukuoka city →countermeasures for public work projects are effective to ensure waste minimization Flow analysis on construction material ◆ 1st treatment & 2nd treatment - Similar to flow on sludge ◆ Landfill - High percentage of recovery for construction materials (90%) - Expected to increase recovery rate by ensuring appropriate waste source separation and waste treatment Flow analysis on plastics ◆ Landfill - Amount of landfilled waste: equal to amount of waste generated (0.1 Mt/year) →enough countermeasures for plastics reduction have not been implemented because, 1. one of wastes accepted in “least controlled landfill sites” that can maintain at low cost 2. regulation for dioxins discharge has been tightend ◆ We developed effective analytical method by reviewing treatment process of each classification waste sourcetreatment facilities - Relating information about waste source and treatment facilities process location - Important to analyze data by taking treatment process and waste generation/treatment location into account capital cost - Former utilization system: cost effective from point of view of capital cost of facilities public work projects - Countermeasures for public work projects: effective to facilitate waste minimization 1st treatment Where? -in Fukuoka prefecture - 5 thousand km million people (4%)) Who? -Facilities in Fukuoka prefecture - Intermediate treatment - Landfill - 37,000 data ! (FY 1999)
