The authors focused on the major alternatives towaste collection and transport practices used in Da Nang city. GPS devices and a GIS software<br />
were usedto survey andanalyze the detailed tracking data on 3 currentpractices; “Door-to-door collection by tricycle and transport by truck”, “Door-to-door<br />
collection and transport by truck”, and “Fixed time dustbin collection and transport by truck”.The operation efficiency indicators, such as unit operation time,<br />
person-hours/t and operation velocity were calculated usingadetailed operation category: moving forward and backward, waste collection waste, unloading<br />
and other activities. Usingmulti-regression analysis, the authors estimated the unit loading time and the unit waste amount for 4 types of containers, 240-L<br />
dustbin, 280-L dustbin, 660-L dustbin and Handcart.<br />
Usingscenario analysis in Hoa Cuong Nam ward in the Hai Chau district, the operation efficiency of “Door-to-door collection by was 4.39 person-hours/t,<br />
which was lowest among the current 3 practices, and that of “Door-to-door collection and transport by truck” was 3.70 person-hours/t. “Fixed time dustbin<br />
collection and transport by truck” achieved the highest efficiency of 2.15 person-hours, which was less than half of “Door-to-door collection and transport<br />
by truck”. The operation efficiency of a separate collection of bio-waste by plastic bag was 3.49 person-hours/t. It was better than thedoor-to-door collection<br />
scenarios, which means it would be a feasible alternative that can replace door-to-door collection practices.<br />
The authors also conducted sensitivity analysis to clarify the impacts of policy factors such as truck capacity, collection frequency, and separation rate of<br />
bio-waste. The variation range of efficiency by collection frequency was larger than the range by truck capacity. The authors also found some conditions for<br />
the separate collection of bio-waste by plastic bag with better efficiencies than “Fixed time dustbin collection and transport by truck”, e.g., “7 times per week<br />
for bio-waste and once per week for other waste”. The variation range of efficiency by separation rate was largest among the influence factors considered<br />
in this study.

waste recycling. The authors conducted a waste measurement survey, a waste composition survey, and a questionnaire survey of 103 target facilities<br />
for ten consecutive days. The waste generation rates (WGRs) by worker, table, and business area were assessed by business sources (café (CF), small<br />
restaurant (SR), and large restaurant (LR)) using the following three waste categories in consideration of informal waste collection: general waste (GW),<br />
separated recyclables (SRe), and separated food residue (SFR). WGRs by worker were highest at SRs (5,208 g/worker/day), followed by LRs (3,839 g/<br />
worker/day) and CFs (1,446 g/worker/day). The major waste compositions in GW were kitchen waste (37.1-49.8%), paper (11.4-34.0%), and plastic (8.3-<br />
11.4%). The recycling potential and composting potential remaining in GW were 17.0-20.2% and 30.9-61.6%, respectively. For recycling potential, paper<br />
containers and packaging accounted for a large portion, with 10.6% at CF. In contrast, plastic containers and packaging was the major portion at SR (10.6%)<br />
and LR (7.4%). The total waste amount was estimated to be 38.56 tons/day (34.46-46.35 tons/day, 95% CI); of which 18.96 tons/day (49.17%) was SFR,<br />
18.50 tons/day (47.99%) was GW, and 1.10 tons/day (2.84%) was SRe. The recycling and composting potentials remaining in GW were 3.52 tons/day<br />
(9.14%) and 10.84 tons/day (28.12%), respectively. The SR should be considered as the highest potential target for a 3R promotion campaign in the future,<br />
with recycling and composting potential estimated to be 1.67 tons/day (4.34%), and 6.53 tons/day (16.93%), respectively.

This study focuses on Greenhouse Gas (GHG) emissions and reductions of Municipal Solid Waste<br />
(MSW) incineration. The authors aim to estimate the detailed composition of GHG emissions and<br />
reductions from the waste incineration facility and their influence factors using two Japanese<br />
databases on the operation of incinerators from Japan Ministry of the Environment (1,243 facilities)<br />
and Japan Waste Research Foundation (814 facilities). The databases cover detailed data on MSW<br />
amount and characteristics, specifications of the facility, annual utility consumption, and annual<br />
energy/material recovery. The authors analyze the correlations among them and develop predictive<br />
models for the detailed components of GHG emissions and reductions.<br />
Japan Ministry of the Environment intended to group small municipalities for replacing small-scale<br />
incinerators to large-scale Waste-to-Energy (WtE) facilities with a higher energy recovery efficiency.<br />
Based on the abovementioned data and models, the authors estimate the expected effects of the block<br />
formation and major technological alternatives for GHG mitigation by the national level.<br />
The current net GHG emission rate from 1,243 operating waste incineration plants in Japan in 2009<br />
was estimated to be 653 kgCO2e/t. In the block formation, 1,007 plants were assumed to be closed; 236<br />
kept operating; and 286 facilities would be newly built. The net GHG emission rate could be cut off to<br />
454 kgCO2e/t by applying the block formation and technological alternatives with a higher energy<br />
recovery efficiency (stalker furnace with power generation by extraction condensing turbine providing<br />
steam higher than 3MPa and 300 C). Ash melting caused a larger GHG emission by the increase in<br />

energy consumption. The GHG reduction by slag recycling was limited.<br />
Furthermore, the net GHG emission rate could be reduced to 242 kgCO2e/t by applying the Best<br />
Available Technique (BAT) for combined heat and power plants. When compared with the current<br />
status, BAT can reduce 185 kgCO2e/t by improving the power generation efficiency and 187 kgCO2e/t<br />
by expanding heat utilization. At present, heat utilization is very limited in Japan, but heat utilization<br />
should be more focused and promoted for GHG mitigation decisions.

This study was undertaken to characterize the solid waste generation at educational facilities in Hue, Vietnam. The authors surveyed 35 educational<br />
facilities within six categories of schools for seven consecutive days. The waste generation rates by facility, student, classroom, staff member, and floor area<br />
were assessed by school category using the following three waste categories: general waste (GW), separated recyclables (SR), and separated food residue<br />
(SFR). To determine the potential for composting and recycling from the disposal amount, GW was classified and measured by 10 physical categories and 77<br />
sub-categories. Plastic, paper, and food waste were dominant in most of the school categories. The total waste generated from educational facilities in Hue<br />
was determined by extrapolating the total number of facility/student in Hue and the waste generation rate by facility/student. The total waste generated was<br />
estimated to be 5.76 tons/day, of which 3.29 tons/day (57.2%) was GW, 0.15 tons/day (2.6%) was SR, and 2.33 tons/day (40.5%) was SFR. The authors also<br />
revealed a considerable potential to recycle and compost remaining in GW, at rates of 1.11 tons/day (19.3%) and 1.29 tons/day (22.4%), respectively. The<br />
total amount sent to a landfill could be reduced from 3.29 tons/day (57.2%) to 0.89 tons/day (15.5%). A detailed breakdown of the recycling and composting<br />
potential is also analyzed and discussed for use in policy making decisions. Through the Monte Carlo simulation, the 95% confidence interval of the total<br />
waste amount was estimated to be 4.85-7.71 tons/day.

In Vietnam, most of municipal solid waste (MSW) is disposed of at open dumping and landfill sites, and the methane gas from waste is the un-ignorable source of greenhouse gas (GHG) emission. It is indispensable to explore the possibility for GHG mitigation in MSW management. The objective of this study was to estimate alternative waste treatment practices towards the GHG emission mitigation, energy consumption and generation, reduction of landfill volume, and various benefits for proposing the appropriate selection by scenario analyses for representative Vietnam's cities. Impacts were calculated by utilizing life cycle assessment (LCA) method. A literature review survey on the current applicability of LCA database for assessing impacts from waste sector in developing countries, especially for Vietnam, was carried out. This study assessed the contribution of alternative solid waste treatment practices. The result showed that, except investment and operation costs, incineration with energy recovery seems the suitable alternative for treating waste from representative cities of Vietnam according to reduction of GHG emission and waste burden to landfill sites and energy recovery and generation. Besides, MSW composition was identified as an important factor directly influencing to impacts as well as other products and benefits of waste treatment alternatives. Reliable data on waste composition are indispensable for assessing to choose, improve, or plan the waste treatment practices towards sustainable development. © 2013 Springer Science+Business Media Dordrecht.

Waste disposal is an important part of the life cycle of a product and is associated with environmental burdens like any other life-cycle stages. In this study, an integrated assessment for solid waste treatment practices, especially household solid waste, was undertaken to evaluate the impact contribution of household solid waste treatment alternatives towards the sustainable development by using Life Cycle Inventory Assessment method. A case study has been investigated under various possible scenarios, such as (1) landfill without landfill gas recovery, (2) landfill with landfill gas recovery and flaring, (3) landfill with landfill gas recovery and electric generation, (4) composting, and (5) incineration. The evaluation utilized the Life Cycle Inventory Assessment method for multiple assessments based on various aspects, such as greenhouse gas emission/ reduction, energy generation/consumption, economic benefit, investment and operating cost, and land use burden. The results showed that incineration was the most efficient alternative for greenhouse gas emission reduction, economic benefit, energy recovery, and land use reduction, although it was identified as the most expensive for investment and operating cost, while composting scenario was also an efficient alternative with quite economic benefit, low investment and operating cost, and high reduction of land use, although it was identified as existing greenhouse gas emission and no energy generation. Furthermore, the aim of this study was also to establish localized assessment methods that waste management agencies, environmental engineers, and environmental policy decision makers can use to quantify and compare the contribution to the impacts from different waste treatment options. © Springer Science+Business Media B.V. 2011.

The aims of this study were to explore and assess the household behavior towards recyclable waste discard and household attitudes towards good waste management in the Mekong delta region - southern Vietnam. A questionnaire survey was carried out in 100 households in Can Tho city. The existing household habits for waste discard, storage, collection, and recycling activities were clarified in order to identify the priority problems of these activities. Regarding household behavior towards recycling activities and the purchase behavior of households for avoidable wastes (e.g., plastic carry bags, container and packaging, expired/residual food waste) were explored. The household behavior for reusing the used valuable things instead of discarding and for consuming the products or goods made from recycling materials was also examined. Besides, household attitudes towards good waste management were partly explored; the results found that the neighbor's view and social norms seemed to work for keeping order in waste collection and discard activities. Moreover, the authors also analyzed the interrelationships among the household behavior towards recycling activities, the household attitudes towards good waste management, and individual attributes such as the education level, urbanization level, income, age, gender, and working status. It was found that household attitudes towards good waste management correlated to household behavior towards recycling activities; education level and urbanization level were identified as relevant factors for enhancing waste recycling activities and good environmental attitudes of households.

Plastic solid waste has become a serious problem when considering the disposal alternatives following the sequential hierarchy of sound solid waste management. This study was undertaken to assess the quantity and composition of household solid waste, especially plastic waste to identify opportunities for waste recycling. A 1-month survey of 130 households was carried out in Can Tho City, the capital city of the Mekong Delta region in southern Vietnam. Household solid waste was collected from each household and classified into ten physical categories; especially plastic waste was sorted into 22 subcategories. The average household solid waste generation rate was 281.27 g/cap/day. The compostable and recyclable shares respectively accounted for high percentage as 80.74% and 11%. Regarding plastic waste, the average plastic waste generation rate was 17.24 g/cap/day; plastic packaging and plastic containers dominated with the high percentage, 95.64% of plastic waste. Plastic shopping bags were especially identified as the major component, accounting for 45.72% of total plastic waste. Relevant factors such as household income and household size were found to have an existing correlation to plastic waste generation in detailed composition. The household habits and behaviors of plastic waste discharge and the aspects of environmental impacts and resource consumption for plastic waste disposal alternatives were also evaluated. © 2010 Springer Science+Business Media B.V.

In Vietnam, municipal solid waste (MSW) has being become increasing complex due to variety of reasons as the increasing quantity, changing composition of MSW, rising public awareness and municipal administration policies among different cities and surrounding communities. There is not currently an efficient management system in place for facilities such as storage, collection, transfer, transportation and disposal of MSW. Against this backdrop, this paper attempts to analyze the present system of MSW addressing variety of aspects such as quantity and composition of MSW generation, operational management, legal system as well as financial aspect. The systematic assessment has revealed the problems like lack of legal framework, low coverage, improper waste storage, less encouragement for composting, and lack of proper disposal practices. Finally, an action plan is proposed suggestion for current and future addressing the issues as the operational management, institutional, financial aspect, public participation, environmental education, and legal and policies.

A number of waste life cycle assessment (LCA) models have been gradually developed since the early 1990s, in a number of countries, usually independently from each other. Large discrepancies in results have been observed among different waste LCA models, although it has also been shown that results from different LCA studies can be consistent. This paper is an attempt to identify, review and analyse methodologies and technical assumptions used in various parts of selected waste LCA models. Several criteria were identified, which could have significant impacts on the results, such as the functional unit, system boundaries, waste composition and energy modelling. The modelling assumptions of waste management processes, ranging from collection, transportation, intermediate facilities, recycling, thermal treatment, biological treatment, and landfilling, are obviously critical when comparing waste LCA models.This review infers that some of the differences in waste LCA models are inherent to the time they were developed. It is expected that models developed later, benefit from past modelling assumptions and knowledge and issues. Models developed in different countries furthermore rely on geographic specificities that have an impact on the results of waste LCA models. The review concludes that more effort should be employed to harmonise and validate non-geographic assumptions to strengthen waste LCA modelling. © 2010 Elsevier Ltd.

This study was undertaken to evaluate the quantity and composition of household solid waste to identify opportunities for waste recycling in Can Tho city, the capital city of the Mekong Delta region in southern Vietnam. Two-stage survey of 100 households was conducted for dry season and rainy season in 2009. Household solid waste was collected from each household and classified into 10 physical categories and 83 subcategories. The average household solid waste generation rate was 285.28g per capita per day. The compostable and recyclable shares respectively accounted for 80.02% and 11.73%. The authors also analyzed the relations between some socioeconomic factors and household solid waste generation rates by physical categories and subcategories. The household solid waste generation rate per capita per day was positively correlated with the population density and urbanization level, although it was negatively correlated with the household size. The authors also developed mathematical models of correlations between the waste generation rates of main physical categories and relevant factors, such as household size and household income. The models were proposed by linear models with three variables to predict household solid waste generation of total waste, food waste, and plastic waste. It was shown that these correlations were weak and a relationship among variables existed. Comparisons of waste generation by physical compositions associated with different factors, such as seasonal and daily variation were conducted. Results presented that the significant average differences were found by the different seasons and by the different days in a week; although these correlations were weak. The greenhouse gas baseline emission was also calculated as 292.25g (CO2 eq.) per capita per day from biodegradable components. © 2010 Elsevier Ltd.

This paper presents an economic evaluation of three typical recycling processes for the five main types of waste electronic home appliances (EHA) (TV set, refrigerator, washing machine, air conditioner and personal computer) in Beijing, the capital of China. The main purpose is to identify the formal management framework with economic feasibility for the waste EHA generated in large municipalities of China. It is found that the advanced technologies, which have mechanical processing units, should be introduced to recover more valuable materials from the waste appliances. Net revenues with a range of 90-240 RMB (Chinese currency unit, 1.0 USD ≈ 8.0 RMB) per unit, depend on the type of appliance, could be expected in case of using the most complicated procedures which can separate both metals and plastics from the shredded mixtures. However, the recycling of waste refrigerator and waste washing machine will, respectively, spend about 100 and 6 RMB per unit if solely by simple manual dismantling. Revenues from recycling of the other three types of appliances are positive but quite low in this case. Although positive revenues could be achieved from the isolated evaluation of recycling, the entire management system, which also covers the phases of collection and transportation, is economically infeasible if the waste appliances are bought from the households still at current prices. Based on a survey of the householder's attitude to the cost for waste EHA management, which was conducted earlier, the practical way to construct a formal management system for waste EHA in Beijing is to reduce the citizen's traditional expectation to the values of waste appliances and encourage their transfer to the formal collection system at lower prices. © 2008 Elsevier Ltd.

Serious adverse impacts on the environment and human health from the recycling and disposal of electronic waste have occurred in the past and continue to occur in China today, due to the lack of a national management strategy. With aiming to support the management strategy development, a study was carried out to plan and quantitatively evaluate the optional management frameworks for the selected five main types of large electronic home appliances in Beijing, the capital city and a typically big municipality in China. This paper outlined the main findings yielded from the series of assessment studies which started from the generation amount prediction and material flow analysis of the used electronic appliances, planning and optimization of the collection & transportation frameworks and ended at the economic evaluation of the optional recycling processes for the waste appliances. Although the revenue could be expected from the result of isolated evaluation of the recycling processes, the entire system will be economically unavailable if the used appliances are still collected from the owners at current prices. The traditional understanding of householders on the values of their used appliances should be changed in Beijing and China as a whole. Establishment of a formal collection system that could take back the used appliances at lower prices (less than 40% of the current level) is the key for the construction of a formal management framework with sustainability.

Obtaining the cooperation of citizens to participate in separate waste collection is essential to create a recycling-oriented society. In this research, the degree of change in the citizen participation rate, which occurs when the contents of political measures such as the raising of awareness, provision of information, and the conditions of collection services were changed, was estimated together with the effect on the reduction in environmental load. A questionnaire survey was conducted, targeted at residents of Itabashi Ward, while logistic regression analyses were also conducted to create predictive models for recycling behavior, and sensitivity analyses of the models were carried out to estimate the increase in citizen participation rate achievable through the implementation of various political measures. It was found that the effect of "thorough perception of information" was the largest, followed by "minimization of evaluation of trouble" and "thorough perception of efficacy of measures." The effect of the improvement in the citizen participation rate on the reduction in environmental load was also evaluated quantitatively by life cycle inventory analyses. It was indicated that "maximization of perception of information" had the greatest effect. However, the reduction effect with "paper packs" and "PET bottles" was relatively small compared with that of "bottles/cans.". © 2007 Elsevier Ltd. All rights reserved.

To assist in the efficient surveillance against illegal dumping, this study examined and evaluated two methods to illustrate the illegal dumping potential of sites using GIS (Geographic Information System) data. One approach focused on the occurrence of illegal dumping sites; the other on the size of the illegal dumping. Both approaches to zoning were implemented for the Kanto region of Japan, utilizing seven or eight major geographical attributes most closely related to illegal dumping. The zoning results revealed the areas requiring patrols against illegal dumping. Evaluation of the zoning results using the ROC (Receiver Operating Characteristic) curve showed the number of illegal dumping sites detectable under certain surveillance conditions and that the size-based zoning was superior, but this superiority was insignificant for revealing sites with higher potential for large illegal dumping, for which it would be sufficient to use the occurrence-based zoning. The evaluation also showed the contribution of each geographical attribute. Finally, application of the ROC curve to the surveillance planning process was examined, which enables the total social cost of pollution by illegal dumping, rehabilitation of dumping sites, and illegal dumping surveillance to be minimized. © 2006 Elsevier Ltd.

The draft legislation on e-waste prepared by the Chinese national government assigns management responsibility to local governments. It is an urgent task for the municipal government to plan an effective system as soon as possible to divert the e-waste flow from the existing informal e-waste recycling processes. This paper presents a case study implemented in Beijing, the capital city of China, with the purpose of predicting the amount of obsolete equipment for five main kinds of electronic appliances from urban households and to analyse the flow after the end of their useful phase. The amount to be handled was 885 354 units in 2005 and is predicted to double by 2010. Due to consumption growth and the expansion of urbanization it is estimated that the amount will increase to approximate 2 820 000 units by 2020: 70% of the obsolete appliances will be awaiting collection for possible recycling, 7% will be stored at the owner's home for 1 year on average and 4% will be discarded directly and enter the municipal solid waste collecting system. The remaining items will be reused for about 3 years on average after the change of ownership. The results of this study will assist the waste management authorities of Beijing to plan the collecting system and facilities needed for management of e-waste generated in the near future.

Serious adverse impacts on the environment and human health from e-waste recycling have occurred in the past and continue to occur in China today, due to a lack of national management strategies. China has made great efforts to face the challenges of the approaching peak increase in the domestic generation of e-waste and the illegal shipment of e-waste from other countries. This study examined recent progress and analysed the main problems associated with this issue in China. It was found that the material and the financial flows of e-waste in China had their own specific characteristics. Nearly 60% of the generated e-wastes were sold to private individual collectors and passed into informal recycling processes. More than 90% of Chinese citizens are reluctant to pay for the recycling of their e-waste. This is due to their traditional understanding that there remained value in these end-of-life products. Regulations concerning e-waste in China have been drafted but their deficiencies are obvious. The extended producer responsibilities (EPR) have been introduced but are not well defined. Eight formal facilities have been planned and are under construction or are in operation along the eastern coast of China but it will be difficult for them to compete with the informal processes for the reasons identified during the study.

This study focused on the household solid waste characteristics and recycling behavior modeling. The authors surveyed 150 households in 6 urban districts of Da Nang city, Vietnam. Three surveys were carried out by household; a questionnaire survey, a measurement survey, and a composition survey. The questionnaire included attribute, participation in recyclables/leftover food separation, environmental attitude. The waste amount was separately measured by 66 categories daily for 10 days. <br> The average of HSW generation rate was 231.5 g/cap/day. Compostable waste accounted for 73.0% of total, and recyclable accounted for 13.8% of total. The participation rates of leftover and recyclable separation were 77.3% and 84.1%, respectively. Plastic bottle and Metal can were two popular items with higher recycling rates (72.5% and 63.8%, respectively). The leftover food was recovered mainly by pig farmer (64.1%). Leftover food collection by pig farmer was more popular in suburb districts. For the purpose of recyclable separation, citizens gave recyclables to junk-buyers or waste collection workers for free (53.6%). The structural models for leftover food separation and recyclable separation were developed to clarify the positive and negative factors. From the obtained results, some suggestions were given in order to improve the participation rate on recycling.

岡山大学において構築した中間処理技術に関する技術モデルを用いて、特にストーカ式焼却炉に焦点を当ててそのコスト・環境負荷の区間推定を行った。また、コスト・環境負荷の推定精度を悪化させる要因を明らかにした上で、技術モデルの改良を図るとともに、技術モデルの計算値とメーカー設計値を比較することによりその妥当性を検討した。区間推定の結果、施設によってエネルギー消費量の推定範囲が8,000MJ/tを超え、モデルの信頼性が低いこと、感度分析より発電電力モデルに係る偏回帰係数の変動の寄与が最も大きいことが判明した。そこで、「ごみ焼却施設台帳」を用い発電電力に係るモデルを再構築し、再度区間推定を行った結果、区間推定の範囲が縮小し、ほとんどの施設において、モデルに基づく信頼区間とプラントメーカー設計値に基づくエネルギー消費量の計算値が重なることが明らかとなり、本技術モデルは一定の妥当性があると考えられた。

This paper presents a survey study on the consumption pattern of five main types of electronic home appliances (Color TV, refrigerator, washing machine, air conditioner and personal computer) and the attitudes of householders to obsolete them after utilization in Beijing, the capital of China. There is still space for consumption growth of air conditioner and personal computer while other three kinds have reached saturation. The average life spans of the appliances are found shorter than the anticipated life time. Half of the householders are willing to sell their used appliances to the private collectors due to the convenience and competitive price. Few of them (7%) would like to store the used appliances because of limit living space. 47% of the surveyed people thought the producer should pay for the possible recycling cost. About 85% of them are reluctant to pay more than 50 RMB for per unit of the appliance if required. This study is helpful for the waste electronic appliances generation amount estimation and flow analysis in Beijing and also can be used for the assessment of management frameworks there.
