- Habuer, Haruoka Tomoka, Fujiwara Takeshi

Proceedings of the Annual Conference of Japan Society of Material Cycles and Waste Management 32 23 2021

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

From the viewpoints of marine plastic problems and global warming issues, reduction of marine pollution of plastics and conversion of 3Rs and renewable resources are required. Durable and hygienic PET bottles are indispensable to our lives because of their convenience. However, they account for 6% of the total amount of plastic waste every year in Japan. The purpose of this study is to construct a material flow (MFA) for PET bottle labels in Japan. As the results, the amount of PET bottle labels discarded in 2019 were calculated. The amount of labels calculated using the weight ratio of bottles to labels is about 26,000 tons, while the amount of labels calculated using the average weight of labels is about 25,000 tons. Comparing the two calculation methods, there was a difference of 200 tons for roll labels and 1,000 tons for shrink labels. This is probably because the ratio of roll labels to shrink labels is assumed and the capacity of PET bottles is not distinguished.

Analysis on citizen's discharge behavior of cleaning up waste after disaster : focusing on flood disaster in Mabi town, Kurashiki city

Fujiwara Takeshi, Moriwaki Naoki, Namikoshi Hiroya

Proceedings of the Annual Conference of Japan Society of Material Cycles and Waste Management 31 113 2020

Authorship：Lead author,　Corresponding author Language：Japanese Publisher：Japan Society of Material Cycles and Waste Management

Due to the heavy rain that hit West Japan in July 2018, a large-scale flood occurred in Maki-machi, Kurashiki city due to the river collapse on the 7th, and the heavy rain that hit West Japan in July resulted in 7 in Mabi-cho, Kurashiki-shi. Large-scale floods occurred daily due to river collapse, resulting in approximately 440,000 tons of flood damage. When the house cleaning starts, they are discharged all at once in the area, which causes a shortage of storage space and waiting for garbage collection. In Mabi-cho, there is an illegal discharge site where citizens can bring in garbage by car under the elevated road construction site along National Route 486 and under the Ihara Railway Ihara Line, and the Self-Defense Forces will remove it. In order to control the discharge of clean-up trash immediately after the occurrence of a disaster and to make a plan to collect it quickly, it is effective to first analyze the clean-up trash discharge behavior actually taken by the victims. Therefore, in this study, we conducted a questionnaire survey on the victims of Mabi-machi, Kurashiki city, and analyzed the recognition of discharge rules, the possibility of separation, the place of waste discharge, and the reason why they were dumped at illegal discharge sites.

Proceedings of the Annual Conference of Japan Society of Material Cycles and Waste Management 31 117 2020

Authorship：Lead author,　Corresponding author Language：Japanese Publisher：Japan Society of Material Cycles and Waste Management

Due to the heavy rain that hit western Japan in July 2018, a large-scale flood occurred in Manabi-cho, Kurashiki city on the 7th, which caused about 440,000 tons of flooded waste. When the cleaning of houses starts after the disaster, they are discharged all at once in the area, which causes a shortage of storage space and waiting for garbage collection. In previous research 1), it was found that if the collection of waste is delayed, the storage space becomes full, which causes illegal discharge. In the event of a disaster, it is necessary to smoothly collect and remove disaster waste from the disaster area, and for that purpose, it is important to first understand the characteristics of the waste discharge time of clean-up waste. In this study, we conducted a questionnaire survey on the victims of Mabi-machi, Kurashiki City, clarified the emission characteristics and emission timing of each type of cleanup waste, and created an emission model. Then, for the waste discharge from the target area, a collection strategy was established and a collection simulation was conducted.

Proceedings of the Annual Conference of Japan Society of Material Cycles and Waste Management 26 19 2015

Publisher：Japan Society of Material Cycles and Waste Management

As a first step of research on evaluating effectiveness of distributed biomass recycling system of business facility or regional unit, in this study, we estimated the quantity of biomass waste which is generated from green area, agricultural field, and cafeterias on a big campus of Okayama University. Each quantity of pruned fruits branch, cut grass, rice straw, and animal waste was estimated by using the calculation method of NEDO, crop waste was estimated by using a farm report published by Faculty of Agriculture, and pruned and fallen leaves were estimated by using the allometry method which estimates amount of leaves based on trunk diameter and tree height. The amount of the kitchen waste generated from university cafeteria was figured out by hearing to university Co-op. As a result, it was found that the amount of biomass waste generated on Okayama University campus is 1,454 ton/year. If the biomass is burned or used for bio gas generation, the electricity generation will be 6,765 GJ/year.

Study on Sustainable Solid Waste Management towards Low Carbon Society in Malaysia Iskandar Area

Fujiwara Takeshi, Siti Norbaizura

Proceedings of the Annual Conference of Japan Society of Material Cycles and Waste Management 24 75 2013

Publisher：Japan Society of Material Cycles and Waste Management

Iskandar Malaysia (IM) is a new economic region in Malaysia’s most southern state, Johor. The region is targeted for massive development by 2025 with a targeted rapid increase in the population to 3 million, or double the 2005 level, within the 20-year development period. IM was chosen as the study area of “Low-carbon society for Iskandar Malaysia 2025” which has an action “Sustainable Waste Management” in 12 countermeasure actions towards climate resilient urban development for Iskandar Malaysia. In this paper, we evaluated alternative solid waste management towards the building of both a sound material society and a low-carbon society. This study covers five sectors namely management of municipal solid waste, agricultural waste, industrial waste, sewage sludge, and construction and demolition waste. Our target is half reduction of landfill waste and half of GHG emitted from waste handling and treatment. Our result shows that both the target are achievable in 2025 with the reduction of 65%, 79%, 81%, 10%, 69% of waste and reduction as GHG emission as well, respectively. Targets are achievable under the condition of high participation and segregation efficiency in 2025.

Study on waste characterization survey of household waste and development of prediction model of waste discards

Fujiwara Takeshi, Fujikawa Daiki

Proceedings of the Annual Conference of Japan Society of Material Cycles and Waste Management 24 13 2013

Publisher：Japan Society of Material Cycles and Waste Management

In the recent year, there is the trend of municipal solid waste (MSW) decreasing in many local governments. Some of the reasons of this trend are due to changes in socioeconomic factor such as decreasing in population number and economic stagnation and positive impact factor of 3R – reduce, reuse, recycle; promotion. However, it is difficult to explain the reason of MSW decreasing through decoupling the effects from each factor. It is required for local government to make planning of treatment facility from long time prospect of waste discards. In this study, we conduct waste characterization test to analyze the relationship between consumption and waste discards for targeted Okayama City, and develop a model for projecting future waste discards based on a scenario of economic stagnation or recycling promotion.

Language：Japanese Publisher：Japan Society of Civil Engineers

Pacific island country without having manufacturing industry emphasizies on tourism industry which utilizes the natural resources. Island country imports lots of foods and commodity goods from oversea countries to supply for tourists during their stays, moreover, changes in resident's lifestyle from 'thrift type' to 'waste type' increases the amount import even more. The goods consumed by resident or tourist, has been disposed and stored in the island, and at present, the stored waste causes environmental pollution and landscape deterioration. Since small island country has difficulty in constructing final landfill, it is important to prevent waste generation due to construct a sound material-cycle society with a view of collaboration with foreign countries. For this purpose, by considering development in island economy and change in lifestyle of island people, it is necessary to identify the quality and quantity of solid waste which is generated at the present and future. In this research, Guam, a territory of U.S., is targeted. First of all, input-output table is developed to grasp the current economic situation of the island, and secondly, scenarios which are composed of changes in population of residents, future number of tourists, and expenditure to tourism industry are created. Then, the amount of discharged future household waste is estimated by considering economic ripple effect under the scenario.

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.

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.

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.

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.

Industrialization and urbanization result in significant changes in lifestyle. These lifestyle changes seem to lead to unsustainable consumption patterns and increase the generation of various kinds of environmental loads, especially the amount of municipal solid waste (MSW). Taiwan is a small island with scarce natural resources. The economic development in Taiwan has resulted in the generation of large amounts of MSW. As a result, the Taiwan Environmental Pollution Administration (TEPA) has produced regulations for waste minimization and has imposed several important policy measures that have successfully reduced the MSW discard rate in recent years and have established a public recycling network as a part of the MSW collection. Nowadays, the objective of the MSW policies in Taiwan is to develop a "zero-waste society." This article aims to review the MSW management progress in Taiwan and to project future MSW discards up to 2011 based on the national plan and assumed scenarios for socioeconomic variables. According to the analysis results, a more sustainable consumption pattern can be proposed and the corresponding MSW management system can be planned so as to develop a low-waste-discard society. © 2009 Springer Japan.

The policy of waste to energy (WTE) has been promoted as an important policy for alternative energy and one of the principle infrastructure plans of the Japanese government. However, problems with dioxin have necessitated various changes of WTE technology, and WTE facilities now must have flue gas treatment equipment with long-chain process , ash melting furnace , and gasification and melting furnace. Although WTE facilities with the disposal capacity of 300t/d or greater have been considered to be more effective and desirable, the number of these facilities has not increased, and WTE facilities with capacity of less than 300t/d have been increasing in compliance with the dioxin guidelines for continuous combustion and regional waste disposal. This study investigates and analyzes the generation, purchase and consumption of electricity / fossil fuels using the operation and maintenance data of all of WTE facilities operated in 2007 in Japan. Our findings show that the smaller the capacity of WTE facility , the greater the consumption of electricity and energy per ton. In the future it may be recommended that WTE facilities of 300t/d or greater be increased and the ash from several WTE facilities be treated jointly.

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

A one-month survey focused on 100 households was conducted in Can Tho City. The household solid waste was collected from each household and classified into 83 categories. The results showed that the average household solid waste generation in Can Tho City was 0.29 kg per capita per day with high compostable portion and recyclable as 82% and 10%, respectively. The household solid waste generation rate (kg/cap/day) was positively correlated with the population density, while it was negatively correlated with the household size. Moreover, the discharge amount per capita per day of household solid waste by each fraction is positively correlated with the urbanization level.

Estimation of greenhouse gas emitted from municipal solid waste treatment and disposal in taiwan and its policy implication

Yu Chi Weng, Takeshi Fujiwara, Yuzuru Matsuoka

Journal of Global Environment Engineering 14 47 - 55 2009

The increasing municipal solid waste (MSW) generation and the options of appropriate MSW treatment technologies are particularly highlighted on its worldwide impact on the global warming in recent times. It is imperative to assess the potential amount of the greenhouse gas (GHG) emission in the design of MSW treatment and disposal system. This study aims at developing an emission inventory of GHG emission from the MSW treatment and disposal system, by firstly using the IPCC's updated methodology and domestic studies for required parameters in Taiwan. The GHG emission rates from respective MSW treatment and disposal divisions are estimated. The methane emission behavior between the first-order decay model and the triangular method is also firstly compared. Accordingly, the MSW treatment and disposal system in Taiwan generated 7,842.6 Gg CO< equivalence in 2002, occupying 2.86 % of Taiwanese net GHG emission in that year. The analysis results also indicate that plastic waste, paper waste, and food waste occupies the largest share of GHG emission from MSW treatment and disposal processes. Thus recycling and reducing activities on them should be enhanced for preventing global warming. The results will help the decision-makers associated with GHG reduction and MSW management to make efficient policy strategies.

Language：Japanese Publisher：Japan Society of Civil Engineers

The waste collection and transfer system is requisite for establishing widen regional waste management in prefectural level. In this study, we propose a new method to estimate transport distance between collection area and the waste transfer facility by using GIS and to solve optimal location problem of the facility. Takahasi block, that is a group of local municipalities located in the northern west of Okayama prefecture, is selected as a target area of this case study. Firstly, waste emission map is created based on not only the information of collection area and municipal solid waste by the treatment facility but also the information of population and households by the town. Secondly, we proposed an algorithm of generating a group of the adjusted waste collection area so that waste collection volume in the area can approach to the loading capacity limitation. In order to evaluate the distance between the collection area and the transfer facility, 'the weighted average transport distance with the waste amount' per one trip of collection car is proposed. Finally, the one-dimensional search method along the trunk line is applied for solving the location optimization problem of the waste transfer facility. Additionally, this result is compared to the transport distance of the current treatment condition based on local incineration, moreover, the proposed models is compared to Grid City Model.

Capacity planning of municipal solid waste (MSW) processing system, including the intermediate treatment and disposal facilities, is crucial in MSW management system, especially for the developing countries. Inappropriate intermediate treatment and disposal of MSW would lead to detrimental damage to the public health and natural environment. Moreover, the MSW emission rate in terms of the socioeconomic changes should be further considered in the capacity planning on MSW system. By using the estimation model system of MSW emission, established in the author's previous work, this study aims to conduct a short-term capacity forecasting of MSW processing system, up to 2011. Possible ranges of the available remaining capacity of MSW processing system are projected based on the assumed scenarios. Such capacity forecasting will provide necessary information for the policy decision-makers.

An estimation model of household's waste which is available for local government to make plans of waste management was developed. The mass of household waste is estimated using household's final consumption expenditure, household's attributes, price of goods, and waste conversion rate. The model is a comprehensive multilayered model representing consumption structure. LES (Linier Expenditure System) model is applied to disaggregate the fmal consumption expenditure to expenditures of major consumption categories, and the multinomial logit model is applied to disaggregate the major consumption expenditure to expenditures of intermediate consumption categories, constant rate is used to disaggregate the intermediate consumption expenditure to the expenditures of small categories, and the expenditure disaggregated finally is converted to the mass of corresponding waste category. This model was applied to estimate the waste generation of Kyoto city using the census of household consumption, as a result, effectiveness of the model was proved through evaluating error in the estimation of kitchen garbage.

Social, economic and environment is a composite dynamic system."Mass production, and mass consumption, and mass discarded waste" has been a popular phenomenon in modern society, especially in developing countries. Literatures have indicated consumption is a driving factor of environmental loads but only few give quantitative results. In this study, individual's waste generation by waste component category is simulated via simultaneous equation system regarding for the consumption structure by a case study of Taiwan. Firstly, precise estimation models are developed, and analysis results not only identify the household waste generation loads of consumer's behavior explicitly, but also provide an analytic framework to evaluate performance of relevant policies.

In this study, we applied energy end-use model to estimate air pollution emissions by considering the use ofenergy devices which are decided from energy demand. In the second, the total emission with time variation that wasemitted from sectors was disaggregated into the regions of target area, and finally, by using the meso-scale metheorologymodel (MM5) and the chemical transfer model (CMAQ), the chemical transformation and transportation at the presentand in the future were computed in the three different spatial scales. Accuracy in long range transportation of thedeveloped model was validated through comparison between the estimated value and the observation by the East Asian Monitoring Networks. From the result of finest domain, the background concentration of NO₂ was 2-4 ppb in the year average concen trationand about 19 ppb in the maximum of day average concentration, and the possibility was clarified that NO₂ concentrationin Beijing sometimes is pushed up over Chinese standard of air quality by the NO₂ transported from the outside. Moreover, SO₂ and NOx emissions in 2020 were estimated by the end-use model, and the concentration of the each gasin Beijing was calculated and analyzed. As a result, the concentration in 2020 was over three times higher than that in 2001, and it was specially pointed that SO₂ in winter and NO₂ in summer are remarkably high.

In order to clarify the actual conditions of emissions of environmental loads in Asia, we estimated emissions from energy consumption and agriculture in 2001 and developed emissionsinventories with ArcGIS. To estimate the emissions of NOx, SO₂ and CO₂ from energy consumption, we calculated theservice demands of each sector by using economic model and constructed the energy enduse model. We also estimated the emissions of NOx, SO₂, CO₂, CH₄, NH₃ and N₂O from agriculture in eachemission resource. Then the emissions are spatially distributed by using the landuse data and largepoint source (LPS) data such as electric power plants including its longitude and latitude data. As a result, we estimated total emissions of NOx, SO₂ and CO₂ are 31.1 (Tg), 29.5 (Tg), 6026.2 (Tg), and the large amount of the emissions is from electric power plants. The results of spatialdistribution of these gases show that these gases have concentrated exhaust source on a specific place. We also estimated emissions of CH₄, NH₃ and N₂O from agriculture are 69.4 (Tg), 15.0 (Tg), 3245.8 (Gg), and the largeamount of these gases is emitted from the north part of India.

Recently, Information Technology (IT) has spread quickly in Japan. In this study, we developed a model to estimate the influence of IT on industrial economy and to estimate the related environmental load. This model consists of two modules, input-output analysis module and energy conversion module. The former module estimates multiplied effects of adoption of IT on industry economy, and the latter module calculates CO₂ emission by using the relationship between the emission and industrial production. An IT spreading scenario including evolution of broadband network, electronic commerce (BtoB and BtoC), and telework was considered. As a result of our estimation, demand for power sector increased, and CO₂ emitted from oil products decreased due to reduction of transportation. Total CO₂ emission increased because of large amounts of demands for the power sector.

Proceedings of the Symposium on Global Environment 10 245 - 250 2002

Publisher：Japan Society of Civil Engineers

Sixty percents of people in the world live in Asian area, and their economic activities earn twenty four percents of the total GDP all over the world. As the population increases and the economic activities, emissions of sulfur oxides and nitrogen oxides from combustion are increasing and the emissions cause not only local pollution but also global environmental pollution. It is important to calculate the concentration of sulfur oxides that is emitted from the stack of large point sources. In this paper, a software package was developed to calculate the diffusion of sulfur oxides which is emitted from Asian large point sources by using the Japanese air pollution model, and this package was applied to diffusion problems by large point sources China, Korea and India's. The result is displayed as figures with GIS and the diffusion in each country was discussed.
