A comparative analysis of the psychosocial impacts of waste disposal facilities

This paper reports the results of a comparative analysis of the psychosocial impacts of municipal solid waste disposal facilities (both landfills and incinerators) in six communities in the provinces of Ontario and British Columbia, Canada. Telephone surveys were administered to random samples of residents living around each facility between 1990 and 1995 (total n=1203). The results of logistic regression analyses show that type of facility was the strongest predictor of residents' awareness, concern, and actions taken in response to site concerns. Essentially, residents living in close proximity to a landfill had a higher probability of reporting awareness, concern or actions than residents living around an incinerator site. There was little evidence of differences in reactions between Ontario and British Columbia (BC) residents, despite variations in provincial policies on waste disposal. The effects of other predictors, with the exception of involvement in the local community, were not consistent, supporting previous findings that the determinants of facility impacts are outcome‐specific. It is essential that environmental managers take this constellation of factors into account in the operation of existing, or siting of new, facilities.     

Some more polluted than others: unequal cumulative industrial hazard burdens in the Philadelphia MSA,USA

The aim of this study was to quantify inequities in environmental hazard burdening in the 357 towns and 12 city planning analysis areas in the nine-county Philadelphia Metropolitan Statistical Area. Points were assigned to 14 types of hazards, including Superfund sites, hazardous waste facilities, landfills, trash transfer stations, waste tyres, incinerators, power plants, polluting factories, and sewage and sludge treatment facilities. When points were summed, 39 communities were in the 90th percentile for total hazard points. Risk ratios were calculated for community characteristics. The risk of extensive hazard burdening was significantly greater for communities bordering the Delaware River and for communities with more than 3% minority residents, more vacant housing units, and adults without a high school diploma. Risks were significantly lower for the most affluent communities. Results point to the need to reform environmental laws at the state level to prevent the concentration of environmental hazards in vulnerable communities.

Effects of an educational campaign on public environmental attitudes and behaviour in Poland

This paper examines the effects of educational campaigns on municipal solid waste management in Jasło City (Poland). In Jasło, a separate waste collection system for recyclables was introduced 11 years ago. Although household segregation was extensively promoted, the quality of recycled materials collected remained low. The City Council decided in 1999 to adopt a British approach to public education, based on home advisors (selected from the local schools and trained on the sustainable waste management principles) visiting as many households as possible, informing residents about the local waste segregation system, conducting a short survey about residential attitudes and behaviour, and providing people with appropriate educational materials. In 2003 and 2004, home advisors visited 687 households in the private housing estates situated in 37 streets of the city. Their effectiveness and the tonnage of recyclables segregated were monitored across the city. The educational campaign has proved a success, resulting in an increase in recycled wastes collected and the number of inhabitants participating, with the home advisors having positively influenced the way residents think and act towards the wastes they produce. Residents valued the home advisors and appreciated the involvement of young people in the campaign. The education campaign also impacted positively upon the students’ (home advisors) knowledge about waste issues, and provided opportunities for students’ relatives and the whole local community to become more environmentally conscious, through the process of intergenerational communication and influence.

Willingness to pay for waste management improvement in Dhaka city, Bangladesh

We employed the contingent valuation method to estimate the willingness to pay of the respondents to improve the waste collection system in Dhaka city, Bangladesh. Our objective was to estimate how WTP differs between respondents who received or did not receive door to door waste collection. The methodology consisted of asking people directly about their willingness to pay an additional waste collection service charge to cover the costs of a new waste management project. The mean value of WTP for areas that received waste collection service areas was higher than for residents of areas that did not but the difference was not statistically significant. The aggregate value of WTP of the respondents in Dhaka city was 7.6 million Taka (USD0.1 million).     

A Comparison of Waste Reduction Practices and the New Environmental Paradigm in Four Southern Chinese Areas

On domestic waste recycling, it was found that source separation of domestic waste in mainland China was supported by 85% of the urban population and about 11–13% of the household waste was recovered and sold by the householders for financial gains. It was also found that the lower income group tended to recover a greater portion of waste, indicating that voluntary waste recovery activities in mainland China were carried out largely due to economic reasons. Thus, the Western type of source separation program in which residents are requested to separate recyclables for the community may not be welcomed in mainland China. In Hong Kong, despite the presence of community waste recovery programs, the recovery of domestic waste is only about 6% and is therefore less than those of the mainland Chinese cities surveyed. On the choice of source separation programs, it was found that Hong Kong people ranked familiarity a more important criterion than convenience. Therefore, the collection frequency of recyclables and time and place for setting out recyclables should be as similar to those of normal waste collection as possible to attract high participation in source separation programs.     

Social and environmental injustices in solid waste management in sub-Saharan Africa: a study of Kinshasa,the Democratic Republic of Congo

This paper investigates social and environmental injustices in solid waste management in Kinshasa, the capital of the Democratic Republic of Congo. The urban poor in most parts of Kinshasa bear a huge encumbrance of the solid waste burden and face multiple challenges associated with poor management of solid waste. This situation has resulted in poor and unhealthy living conditions for the majority of the urban residents. The problem of solid waste management in Kinshasa has further been compounded by rapid urbanisation which has occurred in the face of poor urban governance, civil conflict and weak institutional set-up. The combination of these challenges has resulted in increased overcrowding, poor sanitary conditions, lack of water and an unprecedented accumulation of solid waste which have triggered a myriad of urban problems. The worst affected are the poor urban who reside in locations that receive little or no socio-economic services from the Kinshasa Municipal authority. Using secondary data collected through a desk study, this paper argues that the poor solid waste situation in Kinshasa is not only a health risk, but also presents issues of both social and environmental injustices. These issues are analysed within the context of evolving arguments that focus on the need to develop a pro-poor approach in solid waste management that may present an opportunity for achieving both social and environmental justice for the urban poor in Kinshasa.     

Our battle with hexachlorobenzene: citizen perspectives on toxic waste in Botany

The perspectives of residents are brought together in this assembly of statements concerning the management of hexachlorobenzene waste in Botany, a southeastern suburb of Sydney. The paper indicates how residents have responded as participants in public participation exercises, and the contribution made by lay experts in the search for a negotiated solution to the problems of legacy wastes. Resident comments on the role of independent scientific experts, on legal liability, and on the State Government sponsored Commission of Inquiry, indicate the deficit of resources faced by the local community. The paper provides insights into the status of citizen knowledge in environmental controversies and the pitfalls of participatory processes.     

Conflicting views on opposition to LULUs: distributive justice in three Japanese cases of waste disposal facility siting

Local residents often oppose some types of facilities because of their negative side effects, even though they are claimed to be necessary for the public good. These facilities are known as locally unwanted-land-uses, and local opposition to them is often referred to as not-in-my-backyard, usually with a pejorative connotation. However, some studies have challenged this conventional view of local opposition. Given these conflicting views, the present article explores how local mobilisation should be evaluated, focusing particularly on distributive justice. First, the study illuminates how different interpretations of distributive justice lead to difference in views on local opposition. Then, by comparing three waste disposal facility cases in Japan, a distinction between cost sharing and cost overlapping cases is illuminated. The study further develops discussions by pointing out the limits of using this distinction to evaluate local opposition movements and provides insights that can contribute to a fuller understanding of siting conflicts.     

Residents' willingness to pay for improved liquid waste treatment in urban Ethiopia: results of choice experiment in Addis Ababa

This paper discusses residents’ willingness to pay (WTP) for improved liquid waste treatment in Addis Ababa based on data collected in 2011 using random parameter logit model. Findings indicate that respondents are willing to contribute for improved liquid waste treatment with higher quantity and quality. Their mean WTP for the medium improvement scenario is found to be 15.53 ETB (0.93 USD) per month. The compensation surplus tends to increase from the status quo to the alternative scenarios with aggressive improvement. Finally, the paper concludes by indicating the socioeconomic difference across households, and sub-cities need to be considered in designing environmental protection plans for the city.     

Public opinion and solid waste in Bangkok

The problems encountered when seeking suitable locations for landfill sites often include public concern over the potential visual, health and environmental impacts. There have been many attempts to predict the response of residents in an area to a proposed landfill site and suggestions of ways to adequately consult and include the local population in the decision-making process. An alternative approach is described in this article where the residents living in the vicinity of a landfill site in Bangkok were asked how much they would be willing to pay for the landfill site to be closed and the waste taken out of the city. The method used, the contingent valuation method, can provide information on how much people value environmental goods and services. The use of the technique in this instance provided an estimate of the costs of the disamenity effects of the landfill site to the local residents.     

Willingness to Pay for Improving the Residential Waste Disposal System in Korea: A Choice Experiment Study

This study attempts to apply choice experiments with regard to the residential waste disposal system (RWDS) in Korea by considering various attributes that are related to RWDS. Using data from a survey conducted on 492 households, the empirical analysis yields estimates of the willingness to pay for a clean food-waste collection facility, the collection of small items (such as obsolete mobile phones and add-ons for personal computers), and a more convenient large waste disposal system. The estimation results of multinomial logit models are quite similar to those of nested logit models. The results reveal that residents have preferences for the cleanliness of facilities and the collection of small items. In Korea, residents are required to purchase and attach stickers for the disposal of large items; they want to be able to obtain stickers at not only village offices but also supermarkets. On the other hand, the frequency of waste collection is not a significant factor in the choice of the improved waste management program.

Motives as Predictors of the Public's Attitudes Toward Solid Waste Issues

/ Surveys focusing on solid-waste-related issues, conducted over a period of several years, provided data from independent samples of residents of a Midwestern, USA, community. The collection of these data yielded useful information about the relationship between residents' recycling motives and their attitudes toward solid waste management in light of several changes in the solid waste infrastructure of the community over that time. The initial survey assessed baseline beliefs and attitudes, while later surveys were conducted after the implementation of a community educational program and a curbside recycling program. The findings indicated that for recyclers and nonrecyclers, different motives predicted endorsement of solid waste programs and policies. Although a similar percentage of recyclers and nonrecyclers were in support of various proposed programs and policies, concern for the environment was found to be positively related to nonrecyclers' support of proposed programs, particularly before these programs were implemented. Prior to program implementation, motives other than environmental altruism were found to be related to recyclers' support of the programs. Additional findings support the idea that educational programs and increased accessibility to recycling opportunities affect the relationship between people's attitudes toward solid waste management and their recycling motives.     

Costs and benefits of packaging waste recycling systems

This Special Issue provides several different perspectives on the complex issue of packaging waste recycling. It comprises a diverse and rich set of contributions with insights from very different disciplines that range from economics to engineering. All types of “costs and benefits” are addressed in this collection of articles. In addition to the economic and strictly financial impacts of selective collection and sorting of packaging waste, several authors discuss other types of impacts, such as the environmental and social ones. The reader will find articles that address recycling systems as a whole, pieces that focus on specific impacts and detailed discussions of particular material streams or waste management strategies. The Special Issue represents an indispensable resource for academics, policy-makers and practitioners with interests in recycling and packaging waste management.     

How much do people who live near major nuclear facilities worry about those facilities? Analysis of national and site-specific data

Large nuclear waste management, laboratory and electric power generating complexes are a daunting challenge for state, regional and local planners. A survey of 2101 residents who lived near 11 nuclear power plants and US Department of Energy (DOE) nuclear waste management sites and laboratories was conducted to determine how much nearby residents worried about accidents and chronic emissions at the nuclear sites, how much they trusted the sites’ responsible parties, and actions that they wanted responsible parties to take to reduce public concern. Six hundred other people who lived elsewhere in the US were a comparison group. Nuclear site-related issues were a greater concern among the 2101 who lived near the sites than the comparison group. Yet many were more concerned about global warming, traffic congestion, and loss of open space than nuclear technologies. Monitoring the environment and people were the actions deemed most likely to reduce public concern. The results pose a challenge to owner-operators of nuclear facilities, government entities and especially to locally based environmental planners and managers to establish partnerships with each other and diverse communities that will allow them to manage some of these risks for decades and in some cases into perpetuity.     

Voluntary recycling despite disincentives

This paper assesses the determinants of take-up of a voluntary waste separation scheme, in a scenario where residents sorted, stored and paid for collection of recycling waste even though mixed waste was collected at the kerbside more conveniently, free of charge and without any quantity limits. Uptake of the scheme was positive, persistent and diverse across localities, offering an opportunity to assess the factors determining voluntary participation in the presence of disincentives. We employ a unique panel data-set (n = 4,644) from Malta, including data on recyclable waste kilogrammes collected over the first 86 weeks of the scheme's operation. Drawing on insights from environmental economics and psychology, a model is empirically estimated. Results indicate that uptake is suppressed by the initial constraints households may face and stimulated by collection frequency. Political vote is an important determinant of participation and this interacts with scheme promotion to create diverse uptake rates.     

A new system for groundwater contamination hazard rating of landfills

In developing countries, several unregulated landfills exist adjacent to large cities, releasing harmful contaminants to the underlying aquifer. Normally, landfills are constructed to hold three types of waste, namely hazardous waste, municipal solid waste, and construction and demolition waste. Hazardous waste and municipal solid waste landfills are of greater importance as these pose greater hazard to groundwater, in comparison with landfills holding waste from construction and demolition. The polluting landfills need to be prioritized to undertake necessary control and remedial measures. This paper assesses existing site hazard rating systems and presents a new groundwater contamination hazard rating system for landfills, which can be used for site prioritization. The proposed system is based on source-pathway-receptor relationships and evaluates different sites relative to one another. The system parameters have been selected based on literature. The Delphi technique is used to derive the relative importance weights of the system parameters. The proposed system is compared with nine existing systems. The comparison shows that the site hazard scores produced by the existing systems for hazardous waste, municipal solid waste, and construction and demolition waste landfills are of the same order of magnitude and tend to overlap each other but the scores produced by the proposed system for the three types of landfills vary almost by an order of magnitude, which shows that the proposed system is more sensitive to the type of waste. The comparison further shows that the proposed system exhibits greater sensitivity also to varied site conditions. The application of different systems to six old municipal solid waste landfills shows that whereas the existing systems produce clustered scores, the proposed system produces significantly differing scores for all the six landfills, which improves decision making in site ranking. This demonstrates that the proposed system makes a better tool for prioritization of landfills for adopting control measures and remediation.     

Who will pay? Subsidies or taxes for recycling in the heartland

Attaining recycling goals of 25 to 50% over the next few years will require substantial recycling of residential wastes. A combined program of curbside recycling of conventional post-consumer materials and collection and composting of both leaves and grass will yield a composite diversion rate of 12 to 21% by weight. But in many communities, particularly in the west central and south central states of the American heartland, implementation of such programs will result in a net increase in solid waste management costs. Case studies of four communities in Oklahoma are used to estimate the potential increase in first-year net costs that would result from implementing a combined recycling and yard waste composting program. The results are compared to survey data from Oklahoma and Florida that define the amount residents are likely to be willing to pay for the benefits of recycling. The potential to close the apparent willingness-to-pay gap through state subsidies is then assessed. Where state capital grants programs are insufficient to bridge the gap, and local officials are reluctant to impose costs that are not publicly supported, public education efforts will be needed to increase the value residents ascribe to the nonexclusive positive externalities and local nonmarket benefits of recycling.     

Improvements in financing for sustainability in solid waste management

Contributing elements toward the development of a sustainable solid waste management system in Tucumán, Argentina, are described. Changes in the working environment for the wastepickers have been instrumental in providing a livable wage and diminished health and environmental risks to the wastepickers and to neighboring residents. Income levels to the wastepickers are now approximately 1.75 times minimum wages in Tucumán and are being driven almost entirely by the recycling of plastics. Educational improvements in Tucumán, which are assisting sustainability of the solid waste system, are being significantly improved by the operation of a pilot scale project, by demonstrating opportunities to government officials and school children. Improved financial sustainability to the solid waste management system is also potentially available from carbon credit trading opportunities, presenting the opportunity for 1.2 times the income available from recycling efforts.
