A calibration of the model for screening terraced paddies with higher conservation priorities using field cases of certified terraced paddy districts in Wakayama Prefecture in Japan

OBA Yuki, HARA Yuji, YAMAMOTO Yugo

Landscape Research Japan Online ( Japanese Institute of Landscape Architecture ) 16 5 - 16 2023.02 [Refereed]

　View Summary

In this study, we improved and further developed the existing GIS-based model for screening terraced rice lots in its conservation priority with focuses on three aspects; landscape value, agricultural efficiency and disaster prevention function. Then the model was applied to the Wakayama Prefecture area within the Kii Peninsula region in central Japan, in which has a clear north-south gradient in geological features. As the results, constructed model performed effectively in selecting rice lots with higher conservation priority within 10km spatial scale. Moreover, in the northern part of the prefecture, agricultural efficiency was an important aspect in the model, whereas landscape value and disaster prevention function were also detected in the middle and southern parts, respectively. Prefectural governmental officials in charge of terraced paddy conservation policies, who were interviewed, supported an applicability of this model in actual institutional fields because it was guaranteed by scientific approaches. Based upon these figures, we proposed that at prefectural spatial scale the model calibrated among three aspects depending on geologic and topographic conditions could be utilized for prioritizing terraced paddies without serious regional inequalities in institutional supports.

Estimating Redundant Capacity of General Waste Treatment Facilities to Dispose Waste Plastics Subjected to Import Restriction in Asian Countries:Considering Maximum Load Capacity of Exhaust Gas Treatment Facility

TANI Yuto, NAKAO Akifumi, YAMAMOTO Yugo

Papers on Environmental Information Science ( Center for Environmental Information Science ) 34 97 - 102 2020.12 [Refereed]

　View Summary

In this research, we estimated a redundant capacity of general waste treatment facilities in Kinki, Chubu, Chugoku and Shikoku region to treat the waste plastics subject to import restriction in Asian countries ("restricted waste plastics"). A calorie-based calculation under assumption of the maximum load capacity of exhaust gas treatment facility was conducted in this estimation. From the analysis, we obtained the following conclusions; 1) The amount of restricted waste plastics generated in the study area was 916,300 tons per year, 2) In case that the restricted waste plastics were accepted at the facilities where the power generation efficiency were more than 21%, only 10,100 tons per year of restricted waste plastics could be treated in domestic facility, 3) The general waste treatment facilities in the study area had potential to treat 893,300 tons per year of restricted waste plastics if the criteria of power generation efficiency was more than 12%.

Effect of environmental infrastructure collaboration and sludge treatment aggregation on GHG reduction by sludge fuel utilization corresponding to industrial society change in future

荒木浩太朗, 中尾彰文, 道浦貴大, 山本祐吾, 吉田登

日本地域学会年次大会学術発表論文集(Web) ( JAPAN SECTION OF THE REGIONAL SCIENCE ASSOCIATION INTERNATIONAL ) 54th ( 2 ) 203 - 219 2017 [Refereed]

　View Summary

 In this study, we analyzed the effect of GHG reduction by utilizing various sewage sludge fuels based on collaboration among sewage infrastructures, industrial infrastructures, and domestic waste incinerations as well as sludge treatment aggregations from 2020 to 2030. First, we estimated the amount of un-utilized sludge, and acceptance capacity of sludge fuel at industrial factories and municipal incinerators. Second, we extracted the small-sized sewage treatment facilities that were expected to be aggregated with river basin sewage systems. Then, GHG reduction effect was analyzed with respect to the GHG inventory of fuelization technologies and allocation rules of sludge fuel. As a result, collaboration can recover energy from 87.3% of the un-utilized sewage sludge, and reduce 3,900 thousand tons of carbon dioxide. In addition, GHG reduction influences the production of industrial infrastructures in future and mixed combustion ratios in the pulp industry.JEL Classifications: Q29, Q42

Journal of Japan Society of Civil Engineers, Ser. G (Environmental Research) ( Japan Society of Civil Engineers ) 73 ( 6 ) II_189 - II_200 2017 [Refereed]

　View Summary

 As a whole, Japan enters under a population decline, and the tendency is more remarkable in the local area than city area. If the work load and the consumption of supplies of public works are not reduced, the sustainability of the public services will be lost for the cost and environmental problems in such a area. The purpose of this study is to propose the sustainable system on the cooperation treatment of domestic waste water and combustible waste. Some measures were proposed, for example, the introduction of garbage disposer for the efficiency of the combustible waste collection and methane fermentation for combustible waste. Per person GHG emission and treatment cost were applied for evaluation indicators and calculated. As the results of examination for the area where a population decline was remarkable, the proposal systems can improve the efficiency compared with the present condition on the aspect of GHG emission and cannot improve on the aspect of treatment cost. The difference in the results was almost caused by labor cost and contract cost.

　View Summary

 One of the effective means for reducing carbon dioxide emissions for the purpose of alleviating global warming is by increasing carbon fixation in the ecosystem through forest management while fixing carbon by storing it in timber used for furniture or construction materials, as well as using timber as bioenergy as a substitute for fossil fuel. The goal of this study is, by evaluating of carbon fixation in timber and the fossil fuel substitution effect, to develop a simulation model to support the overall optimization of a timber production and utilization system. The biogeochemical model (BGC-ES) based on the forest management model was employed to estimate carbon fixation of a forest ecosystem and the annual production of timber. Cases of forest management comprised combinations of timber harvest cutting periods and annual thinning area ratios. The simulations up to year 2100 were conducted with 2010 set as the base year. For each forest management case, a comparison was made from the balance of supply and demand. Timber was set to be used as building materials, woody powder and woody pellets. The amount of demand was proportionally decrease with the population. Based on the grid search, the maximum peak of cumulative carbon fixation in the ecosystem was recorded in the 90 years of rotation length and the annual thinning area ratio was 6 [%·y-1] (Case HY90t06). While the cumulative amount of timber production was at a maximum when the rotation length was 40 [y] and the annual thinning area ratio was 6 [%·y-1] (Case HY40t06). In case HY90t06, the amount of cumulative carbon fixation in the ecosystem and based on timber increased by 0.7, 3.1 [Mt-C] in 2100 respectively, in comparison with 2010. As the result, in case HY90t06, the net cumulative carbon was estimated to be 2.7 [Mt-C] in year 2100.While, in case HY40t06, the amount of cumulative carbon fixation based on timber increased by 5.8 [Mt-C], however the amount of cumulative carbon fixation in the ecosystem decreased 0.9 [Mt-C] in 2100. Regardless the most of timber was used for biomass power plant , fossil fuel substitution effect is less than other energy production, thus, the net cumulative carbon was estimated to be 1.6 [Mt-C].

SUSTAINABILITY SCIENCE ( SPRINGER JAPAN KK ) 8 ( 4 ) 515 - 527 2013.10 [Refereed]

　View Summary

This study aimed to assess Japan's recent "local production for local consumption" (LPLC) movement, with a special focus on vegetables in the Osaka city region of central Japan. After collecting statistics and spatial data, we conducted a multi-scale analysis of vegetable production and consumption along with the associated energy consumption, using geographical information system software at three spatial scales along the vegetable flow paths: national, regional, and local. Vegetables consumed in the Osaka city region came from prefectures throughout Japan, and we mapped the foodshed within this region at 1-km spatial resolution, as well as the distribution of farmland, farmers' and other markets. We also conducted a scenario analysis for reduced energy consumption through organic farming and the utilization of abandoned farmland near a city to replace food imports from distant areas. We found that the large majority of vegetables consumed in the Osaka city region currently come from remote prefectures, and that this is associated with a high level of energy consumption. Inside the Osaka city region, peri-urban vegetable farming contributes to regional vegetable provision, resulting in an approximately 70 % production/consumption ratio within an 80-km radius of the urban center; if all of the area of abandoned farmland were restored to production, this ratio would increase to approximately 75 %. Organic farming activities that bring together farmers and urbanites are emerging in many parts of the study area, contributing to increased LPLC. Scenario analysis suggested that a decrease of more than 1 x 10(6) GJ of energy inputs could be achieved through wider adoption of local organic farming for local consumption and complete utilization of abandoned farmland in the Osaka city region.

　View Summary

 This paper focuses on carbon footprints of steel production in China. Following the enforcement of the Kyoto Protocol in 2005, China has promoted energy efficient technological renovation in existing industrial zones as well as by the construction of new environmentally-friendly industrial zones. On the contrary, geographical fragmentation of production in China and East Asia has deepened the interdependency on regional transactions of goods and services that are part of spreading global value chains or vertical specialization. Based on the above background, we attempt to evaluate the multi-regional carbon footprint of steel-related low-carbon technological renovation by using input-output analysis. First, we created a dataset for input coefficient changes in an I-O table, corresponding to the low-carbon technologies that are implemented in the “global sectorial approach” to the steel industry. Second, we set up scenarios to implement a set of low-carbon technologies in the steel sector. Finally, we evaluated backward and forward linkage effects of low-carbon technology transfers in terms of their carbon footprints. As a result of the analysis, it was revealed that: 1) implementation of low-carbon technologies would provide a significant contribution to carbon footprint reduction in steel production; 2) the structures of carbon footprint reduction are different among regions due to variations of multi-regional steel production and consumption linkages; 3) the interdependencies among the different carbon footprints in each region can be used as basic information regarding regional collaboration to reduce carbon dioxide emissions in the spreading global value chain.

　View Summary

 Agricultural ecosystems can provide high quality biomass production as an ecosystem service. On the other hand, intrusive agriculture and searching for higher profitability, has induced enormous Green House Gas (GHG) emissions from agricultural ecosystems. In this way, trade-off between mitigating climate change and benefiting from biomass production ecosystem service has occurred. This trade-off is especially evident in greenhouse horticulture because of the requirement of high quality biomass production. Against this background the goal of this study is to develop a co-benefit approach between reducing GHG emissions and sustaining biomass production in greenhouse horticulture as a flagship model of solving this trade-off structure. Biomass production and GHGs emission from soil were analyzed using DNDC (DeNitrification DeComposition) model. Fuel consumption for heating was analyzed using a tool for estimating greenhouse heating fuel consumption. GHGs emission reduction by means of greenhouse temperature management and fertilizer use reduction was analyzed. As a result, the case study plant was found to be using excess fertilizer. Reducing fertilizer use by 45 % was found to have limited effect on the biomass production. Environmental efficiency defined as the ratio of biomass production and GHGs emission was found to be at its highest when fertilizer use was reduced by 47% and the greenhouse temperature was lowered by 3 at the case study production plant.

　View Summary

 In this research, the energy and material flows in the glasshouse horticulture of flowers and ornamental plants were identified based on the field and interview survey at a specific site located in Arida district of Wakayama Prefecture, Japan. In addition, a quantitative analysis was conducted to estimate the GHG emissions derived from each energy and material consumed in cultivation process, applying Life Cycle Assessment (LCA). Furthermore, we developed seven alternative options of heating equipment used in glasshouse horticulture and then evaluated GHG emissions reduction potential through introducing low-carbon equipments in substitution for conventional oil boiler and utilizing woody and waste biomass for fuel based on the result of LCA. From the analysis, we reached the following conclusions: (i) The GHG emissions from glasshouse horticulture account for 98% of the entire emissions and almost all of them is induced by heavy oil combustion in conventional boilers for heat generation. (ii) The installation of wood chip boilers into glasshouse horticulture plant and promotion of woody biomass utilization can reduce GHG emissions by 64%, compared with conventional oil combustion. (iii) As an electric heat pump produces heat greater than the electricity consumed, 59% of GHG emissions can be reduced through replacing conventional oil boiler by it. (iv) The monetary value of carbon credits gained by installing wood chip boilers into glasshouse horticulture plant is estimated at about 36 thousand yen per year if the domestic market price of credits is 1.5 thousand yen per ton CO2.

　View Summary

Sulfided, phosphorus-added NiMo/Al2O3 catalyst was used for hydrodenitrogenation (HDN) of bio-oil derived from sewage sludge. The as-received bio-oil samples contained approximately 6% nitrogen. The bio-oil was dissolved in various solvents prior to hydrotreatment and the removal of nitrogen compounds was evaluated. The HDN of bio-oil dissolved in xylene at 350 degrees C over phosphorus added NiMo/Al2O3 resulted in a complete denitrogenation of bio-oil and high yield of aliphatic hydrocarbon containing product with moderate heating value. Bio-oil dissolved in non-polaric solvent (xylene) showed 2-3 times higher nitrogen removal than that of protic solvents due to the competition between denitrogenation and deoxygenation. This study reveals that sulfided NiMo/Al2O3 catalyst is an efficient approach to remove nitrogen heteroatom compounds prior to further upgrading bio-oil derived from sewage sludge.

　View Summary

Recently activities in nature-rich residential areas, including an agricultural experience in a rental garden and allotment gardens, and shopping at a fresh fruit and vegetable farmer's market are popular among urban residents in Japan. This indicates a rising demand of urban residents for a sustainable way of living in touch with nature. Thus, schemes that encourage sustainable behavior are necessary in urban and regional environmental planning. It is also important to not increase the net carbon dioxide (CO2) emissions through sustainable behavior to establish a low carbon society. In this paper, a questionnaire survey of LOHAS (Lifestyles of Health and Sustainability) and general consumers in Osaka Prefecture was conducted to identify sustainable lifestyles related to food production and consumption. We also evaluated the effect of a sustainable lifestyle on CO2 emissions based on the results of the survey. From the analysis, we reached the following conclusions: 1) LOHAS consumers have a tendency to participate in local food production activities such as allotment gardens and home vegetable gardens. 2) In addition, LOHAS consumers tend to make their purchasing decisions based on their values regarding health and environmental consciousness. 3) The total CO2 emissions related to daily life activities of a LOHAS consumer is 15% lower than that of a regular consumer. 4) In contrast, LOHAS consumers usually take roundtrips to local farm shops so the CO2 emissions related to transportation is higher than for regular consumers.

　View Summary

 Bio-oil is a renewable and transportable liquid fuel produced by the fast pyrolysis of biomass resources, and it can be used as a fuel for direct combustion with natural gasses and heavy oils. When sewage sludge is utilized as an input material into the bio-oil production, to acquire a sufficient heat source needed in drying the dewatered sludge is essential point for achieving more efficient production system. In this paper, we developed the high-efficient bio-oil production system of sewage sludge utilizing power generated from exhaust heat at incineration plants in Wakayama City, Wakayama Prefecture. We also evaluated the reduction effects in energy consumption and GHG emission based on 4 alternative treatment systems of general waste and sewage sludge. The results of analysis showed that the bio-oil production system of the sewage sludge utilizing exhaust heat at incineration plant would have potential for energy independence. We also found this system could reduce GHG emission by 37.3%, compared with a traditional system in which the waste power generation was not installed at incineration plant and simple incineration technology was applied to sewerage treatment process.

　View Summary

In this paper, we evaluated the effects of consumer's behavioural changes on usage and disposal of home appliances. With the model to estimate the product circulation, first we conducted the sensitivity analysis with the six parameters, namely urbanisation, household size, Gini coefficient, product lifetime and selection rate of used product and high energy efficiency product. Then, secondly we evaluated CO2 emission and e-waste generation from four consumers' different behavioural patterns, which are named as 'Business As Usual' (BAU), 'Rapid Cycling' (RC), 'Chain of Users' (CU) and 'Quality and Wisdom' (QW). As a result, the QW scenario was the best lifestyle in both criteria. Further, RC scenario had an advantage on the reduction in e-waste generation in one hand, but CU scenario reduced more CO2 emission. During the transition era of China from materially poor to rich, it could be one of the solutions to utilise energy-efficient second-hand product to improve the living standards of the poor and replace technologically inferior product stocks in poor households.

 Bio-oil is a renewable and transportable liquid fuel produced by the fast pyrolysis of biomass resources, and it can be used as a fuel for direct combustion with natural gasses and heavy oils. In this paper, we evaluated the reduction effect in greenhouse gases (GHG) emission when introducing the bio-oil production technology into the sewage sludge incineration process, based on the life cycle assessment (LCA). We also developed the scenarios that showed when and how to replace the traditional incineration technology of sewage sludge with the bio-oil production technology in regional scale, and the GHG reduction effect in 6 scenarios were evaluated by applying LCA. The results of analysis showed that the bio-oil production by pyrolysis technology for the sewage sludge would reduce GHG emission by 54.3%, compared with the usual incineration. We also found that to make the transition to a centralized treatment of sewage sludge would reduce GHG emissions and promote the effective utilization of more sewage sludge.

　View Summary

In this paper, we evaluate the effects that consumption patterns have on CO2 emissions and waste generated from electrical and electronic equipment in China. We focus on consumer decisions regarding product selection, usage and disposal assuming that these behaviors significantly influence energy efficiency and the flow of discarded products. Four distinguishing consumption patterns were revealed as a result of a questionnaire and from research literature : "Business as Usual", "Frequent Replace", "Chain of Uses" and "Quality and Wisdom." We also evaluate differences in product flow and environmental impacts from 2006 to 2030. Results show that "Quality and Wisdom" is the best style of consumption with regard to both CO2 emissions and reduction of waste generation. When the effects on living standards are taken into consideration, however, a combination of "Quality and Wisdom" and "Chain of Users" seems to best contribute to an optimization of trade-offs between multiple targets of resource consumption, the release of hazardous materials and economic disparities.

　View Summary

Although the selection of product categories is a deciding factor for the success of eco-labelling schemes, there are no consistent methods for determining selection factors and how to prioritise product categories for developing countries (DgCs). This paper attempts to identify appropriate factors for product category selection and formulate a prioritisation method applicable to DgCs. We first examined the selection factors currently utilised in schemes worldwide by conducting a questionnaire survey of representatives of foreign schemes. Selection factors were illustrated on a plot graph, which indicated the percentage of factors implemented in the schemes of DgCs and developed countries (DGs), and their plausibility assessed when utilised in the schemes of DgCs. In this way, we proposed three groups of factors: an exclusion factor, five core factors and seven operational factors. Then, under the conditions of DgCs, such as socioeconomic issues and availability of data, we used and modified some judging guidelines of the European Ecolabel (the EU Flower), e.g. determining the environmental impacts and potential of environmental improvements, in the scoring method to prioritise product categories by weighting factors. In light of our findings, we utilised the proposed factors and modified the scoring method to prioritise the screened primary list of product categories of Vietnamese manufacturing sub-sectors. By scoring factor-based questions and prioritising in three ways, i.e. following the scoring method of the EU Flower programme, totalling all values with equal weighting, and totalling all values but by doubling the weighting of core factors compared with operational factors, we observed that the weighted prioritisation differentiates priority product categories more clearly than the other methods. We propose the two highest potential candidates for eco-labelling in Vietnam, namely textile/garment and fishery products. (C) 2010 Elsevier Ltd. All rights reserved.

　View Summary

In developing Asian countries, the municipal cooperations are unable to handle the increasing amount of municipal solid waste, which into the uncollected waste being spread on roads and in other public areas leading to tremendous pollution and destruction of land and negative impact on human health. Generation of municipal solid waste increases with the rapid urbanization and accelerated economic development with in the rapidly growing advanced technological societies. The nature of municipal solid waste is a term usually applied to a heterogeneous collection group of waste produced in urban areas, the nature of which varies from region to region. The common problem faced by all developing Asian countries, is the disposal of municipal solid waste and availability of land fill site area. Present study explains the correlation analysis of among different factors of municipal solid waste and the objective is to assess the future municipal solid waste stream in Asian developing countries.

　View Summary

Progressive urbanization and urban activities have negative impacts on energy and material flows. In Shanghai, China, energy demand and natural resources input is increasing rapidly with fast growth of GDP and increase of population. In this paper, a quantitative model for urban metabolism was developed to evaluate the direct and indirect environmental impacts due to the energy and materials consumption in Shanghai, China. Also we estimated CO2 emission, Total Material Requirement (TMR) and Ecological Footprint (EF) for urban sustainability assessment based on the model. The results showed that the rapid economic growth and population increase in Shanghai by 2020 would cause 80 percent increases in TMR over 2004. In addition, we found that the indirect EF by construction materials production would become a large part of total EF in high urban growth period, but the indirect EF by electricity and food consumption would increase in the period of stable urban growth.

　View Summary

Recently, various human resources development projects have been implemented by competitive funds. However, it is not clear that how the higher education institutions establish and operate education system. In this study, we conducted the questionnaires survey for 40 human resources development projects funded by the Special Coordination Fund for Promoting Science and Technology from MEXT, Japan. As a result, the followings were identified: (1) much of the education projects were intended for adult students, (2) a certification system was established in more than 90% of projects, (3) education projects had a tendency to depend on external economic and human resources, (4) more than a half of projects had the plan to built the project-based education program into the regular course of their division. These results indicate the importance of financial aid for educational system change, necessity of more appropriate criteria for project evaluation, and need for certification system other than degree system.

　View Summary

While constant technological coefficients are usual in evaluating energy conversion of biomass waste, future innovation would influence on the evaluated values for developing technologies. In this study, an analysis was made to examine the influence of uncertainty in technological efficiency and business balance factors on reduced carbon dioxide and business feasibility using Monte Carlo simulation. As a result of the analysis, it is clarified that decomposition rates of organic components in pre-treatment stage give great contribution on the uncertainty of reduced carbon dioxide in the case of sewage sludge. We also found that construction cost and treatment charge give great contribution on the business feasibility in methan fermentation of food waste from business activities.

　View Summary

This paper examined practice and evaluation of the experienced-based environmental education program for under graduate students at Expo'70 Commemorative Park in Suita, Osaka. Education impacts of the program were measured by the questionnaire which had 40 question items based on three major criteria-environmental education, social contribution and self-realization-. Before and after the program, the questionnaire survey was conducte against an examinee group of 10 students and 3 control groups. The survey results suggested that examinees' education impacts were characterized by "attitude" and "participation" toward social contribution actions including local environmental conservation activities. Our results also indicated that education impacts were acknowledged not only by the increased items in the post survey, but also by the decreased items, some of which seemed to relate with deeper awareness change in the examinee students through tough experiences offered by the program.

JOURNAL OF RISK RESEARCH ( ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD ) 10 ( 6 ) 821 - 839 2007 [Refereed]

　View Summary

Risks such as health risks derived from hazardous chemicals, energy security associated with electric power supply, and accidental risks at work need to be coped with by professionals in the areas concerned. Risk managers must deal with numerous different topics. They are expected to be familiar with legal requirements, scientific analysis methods, management strategies, and communication skills. Many firms in the USA and Europe already employ certified professional risk managers, including those for environmental risks. In contrast, even though both private and public sectors in Japan have acknowledged the need for risk management professionals, the lack in specialized programs at Japanese institutions has resulted in relatively poor staffing of environmental risk managers at most organizations. In order to meet this increasing demand, a new post-graduate program (representative: T. Morioka) at Osaka University was created as the first comprehensive attempt to train environmental risk managers in Japan. This article analyzes the educational systems for risk management at the graduate and post- graduate level in Japan, and compares the structure of the new post- graduate program at Osaka University with similar domestic programs. We also make an analysis of the skills development and learning outcomes criterion of our program.

　View Summary

This paper estimates the CO2 emission and the cost of introducing Japanese advanced technology to the coal thermal-power-generation sector in China, using a newly developed technology choice model. The model calculates costs and CO2 emission by the development of coal power plants as well as replacement and repair of existing power plants, taking into account socio-economic future scenarios in China. Timing of the introduction and regional differences in China are also considered in the model. As a result, we found that introducing the technology would reduce CO2 emission by 16% in total by the year of 2050 and the delay of the introduction may cause decrease in the CO2 reduction amount and increase in cost.

　View Summary

The advanced loop-closing challenges to promote industrial ecology especially emphasize the utilization of the recovered materials/parts/products in original and principal production system while keeping their original function at the highest level possible. In this study, the evaluation criteria and the framework to evaluate the parts-reusability were developed by applying AHP to planning the reuse-oriented business in the electric household appliances. The results of the analysis showed that three criteria were emphasized by expert judgment in evaluating parts-reusability of electric household appliances:"easiness of the reliability securing", "market value" and "demand for repair parts". Furthermore, the feasibility of parts-reuse of fan motor was enhanced by redesigning the inspection system in reuse process.

Journal of Industrial Ecology 9 ( 4 ) 205 - 221 2005.09 [Refereed]

　View Summary

The closing of material loops is a critical challenge in industrial ecology. It relies mainly on the utilization of recovered materials/ parts/products in the original and principal production system while their original function is retained at the highest level possible. In this study, advanced loop-closing systems for the recycling of end-of-life vehicles and electric household appliances are first designed in "Hyogo Eco-town." Second, a methodology for evaluating the eco-efficiency of these systems is developed. Finally, the eco-efficiency of the designed advanced loop-closing strategies for the two products is evaluated, based on the results of materials flow analysis and life-cycle assessment. The results show that, compared with conventional recycling systems, when an industrial complex and an advanced loop-closing system for end-of-life vehicles are established, the total economic value increases by 114% and the eco-efficiency in terms of the amount of direct material input is improved by 57%. This system permits the utilization of the by-products, wastes, and recovered materials that originate from other industrial sectors as input to production activities. In the case of end-of-life electric household appliances, an advanced loop-closing strategy to lengthen the product life with parts reuse improves the eco-efficiency in terms of carbon dioxide (CO 2) emissions by 4% compared with the conventional replacement of the appliance with a new product along with the material recycling option. © 2005 by the Massachusetts Institute of Technology and Yale University.

The material flow accounting model was developed to calculate a supply-demand balance at a province level in China, and was applied to Zhejiang Province. We also evaluated the effect of reductions in GHG emissions, mineral resources consumption, and land use through the following two alternative options of biomass utilization; Energy conversion and material recovery. The results showed that GHG emissions reduction effects by energy conversion case could be 30Mt-CO_2 and 1.8 times bigger than material recovery case. Yet, the latter could save more mineral resources and land.

Solid waste management in Asian countries: problems and issues

A. Khajuria, Y. Yamamoto, T. Morioka

WASTE MANAGEMENT AND THE ENVIRONMENT IV ( WIT PRESS ) 109 643 - + 2008

　View Summary

Asia has been experiencing very high population growth and urbanization. Asian countries will witness a large population increase, which will have important implications for a variety of urban environmental issues, such as solid waste management. Nowadays, waste management is a major challenge in Asian countries, as it creates environmental problems. The present study reveals the problems and issues of solid waste management in Asian countries and certain important problems and issues that must be addressed in order to achieve public cooperation. At the core of the problems of solid waste management are the absence of adequate policies, enabling legislation, and an environmentally stimulated and enlightened public. This paper aims to identify parameters that help to explain the present situation and to assess the future amount of municipal solid waste (MSW) generated per capita in different Asian countries and how to develop an effective waste management strategy for Asian countries according to economic level.

Proceedings of the 15th Symposium on Global Environment ( Japan Society of Civil Engineers ) 15 195 - 200 2007.08

　View Summary

Rapid urbanization economic development in developing counties has been taking place hand-in-hand with diffusion of household appliances like air conditioner, and residential and commercial energy consumption in those countries will become one of the key factors affecting global warming. This study took Shanghai, one of the biggest cities in China as a case study area, and aimed to predict future (by the year of 2030) energy consumption of residential and commercial sector based on our estimation model of energy demand and CO2 reduction potential. Taking into several CO2 reduction measures, CO2 reduction potential was estimated. The results suggested that our estimation model could provide several useful policy implications and would be applicable to the other cities of China.

　View Summary

Upgrading the products for the extension of their life is the effective strategy in construction of Resources-Recycling society. Actually the upgradable products such as User-made PC (PC; personal computer) are come into the market. In this paper, we try to analyze the conditions that the upgradable products are spread by means of the consumer's choice model. The result of the analysis shows that to give information on the products to the end-users, to increase their skills in using the upgradable products and to improve services to support them promote their decision to choose the upgradable products.
