The new Malaysia modern city, Putrajaya is being developed rapidly according to the transfer of central government functions from capital city Kuala Lumpur. Malaysia government is planning to make Putrajaya the showcase city for 'Pioneer Township in Green Technology' through 'Putrajaya Green City 2025' preliminary study. As part of '3R Putrajaya' that tackles solid waste management, with the target to reduce half of both landfilled waste amount and GHG emission from waste management counter measures compare to the BaU (Business as Usual) case, we developed planning on low carbon collection and treatment of municipal solid waste using GIS software. Base on seven scenario options of waste treatment in 2025, waste transportation route, distance, GHG emission, and cost were calculated. Each scenario options were compared and the best alternative for low carbon waste transportation was proposed.

Intervention Time Series Analysis of the Household Solid Waste Generation in Taipei City

Weng Yu-Chi, Fujiwara Takeshi

Proceedings of the Annual Conference of Japan Society of Material Cycles and Waste Management 21 301 - 301 2010

Language：Japanese Publisher：Japan Society of Material Cycles and Waste Management

In order to modify the waste charging in Taiwan, it is imperative to examine the feasibility and policy effects of the operating pay-as-you-throw (PAST) systems. Therefore, this study aims at analyzing the policy effect of the PAST system in Taipei City where sufficient waste data regarding the PAST is available. Meanwhile, other influencing factors of HSW generation in Taipei City would be exploited so that efficient policy measures for waste reduction could be proposed.

Language：Japanese Publisher：Japan Society of Material Cycles and Waste Management

Japan is one of the countries experiencing the most serious flood disasters in the world. In recent years, flood disasters resulted from intensive heavy rainfall events occur frequently, leading to a lot of victims. When such flood disaster occurs, a large amount of flood disaster waste, e.g. household goods, would be discharge from flood-damaged houses. Hence, in this sense, a lot of problems would happen, such as disordered waste collection and transportation activities and the insufficient emergent capability of waste treatment facilities, etc. However, to conduct quick and proper waste collection and transportation programs, firstly the estimation of flood disaster waste discharge is required. Therefore, take one past flood event in Kurashiki City as a case study, this research conducted a questionnaire survey, estimated the amount of its flood disaster waste discharge based on the survey results in support of waste collection, transportation and treatment actions, and consequently examined the reproducibility of the flood disaster waste discharge process.

Technology Assessment System for the Network of Industrial Waste Treatment and Recycling

Ishida Toshihiro, Fujiwara Takeshi

Proceedings of the Annual Conference of Japan Society of Material Cycles and Waste Management 21 ( 2/3 ) 26 - 26 2010

Language：Japanese Publisher：Japan Society of Material Cycles and Waste Management

Nowadays about 5% of industrial wastes (22 million ton) are not recycled. One reason of this problem is that are unavailable for the factories to look up an optimal process flow. Thus this study aims to develop a technology database of treatment process, cost, energy consumed, and environmental loading of the process for industrial waste so that the most efficient and environmental-friendly process flow can be easily searched. Microsoft Excel is used to establish the platform of the database and to develop the interface of data input. Further, estimation formulas can be performed in this database system and parameters for advanced evaluation can be easily queried. By this developed system, after inputting the initial values of a processing, the whole flow the list of process flow candidates will be shown and the comparisons between the theoretical output and actual measurements can be performed. Further, advanced financial and environmental evaluation of the interested process can be achieved.

RISK ANALYSIS VII: SIMULATION AND HAZARD MITIGATION & BROWNFIELDS V: PREVENTION, ASSESSMENT, REHABILITATION AND DEVELOPMENT OF BROWNFIELD SITES Vol.43 PI681 - PI692 2010

Language：English Publisher：WIT PRESS

In this study, a procedure is established for estimating and assessing the amount of flooding debris following a flood disaster. The per unit generation of flood disaster debris, which takes into account criteria such as the extent of housing damage as a function of inundation duration time, is examined. It is shown that this estimation procedure would make it possible to estimate debris discharge, which is helpful for the establishment of disaster management systems not just as emergency response measures, but also for pre-disaster planning. The proposed Relative Quantity of disaster Debris (ReQD) provides insight that makes it possible to ascertain the emergency response capability of local governments. The ReQDs of selected flood disasters in Japan are examined. For the establishment of effective emergency response systems, it is important to evaluate information on both the ReQD and the quantity of flood debris. From these facts, it is concluded that the implementation of ReQD can help in the establishment of effective support systems with a wide range of cooperative measures for districts in the process of flood recovery and reconstruction, as well as in the emergency response stage.
