The purpose of this paper is to describe the trends in residential solid waste collection (RSWC) services in rural China over the past decade and analyze the determinants of these services using nationally representative data.

The authors draw on panel data from three rounds of village-level surveys of 101 villages. The three surveys were conducted in 2005, 2008, and 2012 in five provinces. The authors used fixed-effected regression approach to analyze the determinants of these services.

The results show that in the aftermath of increased investment and policy attention at the national level, the proportion of villages providing RSWC services in rural China increased significantly from 1998 to 2011. However, half of all villages in rural China still did not provide RSWC services as of 2011. Based on econometrics analysis, the authors show that villages that are richer, more populous, and villages with more small hamlets are more likely to provide RSWC services.

The analyses are based on primary survey data and the first to quantify trends in waste management services in the beginning of the twentieth century. The authors believe that the results will have significant policy implications for China in its continuing quest for better waste management policy.

Privatization continues to receive serious consideration at the federal, state, and local government levels. The most frequent reason cited for privatizing services is to reduce the size and cost of government. While many government entities have privatized services, it is often up to academic researchers to determine if the goals of privatization have been realized and to shed light on the organizational and service characteristics that make it more likely that the results of privatizing a particular service will be positive. This paper seeks to provide a background to those researchers interested in examining the privatization of government services. The paper reviews and synthesizes prior privatization research and discusses future research directions.

This paper investigates residential sanitation collection (RSC) pricing under two different service delivery arrangements: (1) the municipal RSC arrangement where municipal employees collect residential refuse, and (2) the contract RSC arrangement where private sector firms, under contract with a municipality, collect residential refuse. The results of the study indicate that municipal RSC prices are significantly higher than contract RSC prices. Furthermore, municipal RSC prices exhibit greater variability than contract RSC prices. These findings suggest that contract pricing is consistent with pricing in a competitive market.

The paper aims to compare the efficiency of alternative municipal solid waste (MSW) management business models: a single provider against multiple providers.

In this paper the drivers of MSW management costs are analysed to test the impact of the scale and scope of MSW management services on the average cost. While the business-as-usual scenario foresees a single provider, the alternative scenario foresees multiple providers.

Based on the empirical data on municipal waste management costs, on average, the size and the average cost of the service are inversely related. This trend is supported using sub-sets defined by the quantity of waste managed. Multiple factors aid in explaining this result, and among others, due to scale and scope, factors such as transition costs increase with the number of players running different services.

The provision of public services of economic interest should favour the participation of more companies wherever possible to the extent that social surplus is produced. However, pursuing this principle to the detriment of efficient service delivery is not ideal. This paper demonstrated that a single-provider waste management business model is efficient under specific conditions, as in this article.

This paper presents an original research methodology for comparatively analysing waste management service efficiency in urban areas and provides adequate evidence using alternative measures of costs according to the phase of the waste management chain, the scale and ultimately the scope of MSW management services.

本學術論文擬比較另類的都市固體廢物管理模式的效率, 比較的對像是:單一服務提供者和多個提供服務者。

研究人員分析都市固體廢物管理成本和價格的動因, 以測試有關的管理服務之規模和範圍對平均成本的影響。若在一切照常的情況下, 我們會預見單一服務提供者, 唯在不尋常的情況下, 我們則會預見多個提供服務者。

根據都市廢物管理價格和成本上的實證數據, 平均而言, 服務的規模與其平均成本是成反比的。我們使用了以所處理之廢物量來界定的子集來支持這趨勢。多重因素會幫助解釋和說明這研究結果, 其中包括:因規模和範圍的關係, 諸如過度成本等的因素, 會按著提供各種不同服務的主要參與者的數目而增加。

在能達創造社會剩餘的前題下, 會帶來經濟效益之公共服務的提供, 應有利於在可行範圍內有更多公司的參與; 但如果實行這原則而因此有損於服務提供的效率的話, 則這是不理想的。本文展示了在特定的情況下, 單一服務提供者的廢物管理商業模式是高效率的, 本文已說明這些特定情況。

本文為以比較分析法去探討城市地區廢物管理服務的效率、提出了一個新穎的研究方法, 並根據廢物管理鏈的階段、都市固體廢物管理服務的規模、以及最終其範圍, 考慮了成本和價格的另類測量方法, 繼而提供充分的證據, 以支持這些測量方法。

The purpose of this paper is to investigate the management of solid waste during monthly environmental sanitation exercise in different residential areas of Ibadan municipality, Nigeria. The study also examined how the government performed its responsibility during the exercise. This is expected to assist in improving the conduct of sanitation exercise in one of Africa’s populous indigenous settlement, Ibadan.

Collection of data for the study was through participant observation, administration of questionnaire, and interview. As a way of participating and observing, the authors were involved in the conduct of the exercise in the different residential areas of Ibadan municipality. Questionnaire was administered on respondents drawn from one of every ten buildings (10 percent) in the study area using systematic sampling technique. A respondent (preferably a household head) was surveyed from a floor of selected residential building. A total of 367 copies of questionnaire were completed and returned for analysis. Information provided in the questionnaire was analyzed using both descriptive and inferential statistics. Interview was conducted to collect information from the head of environmental sanitation unit in each of the five local government areas of Ibadan municipality.

The most widely used medium of storing solid waste was the polythene bag, which accounted for 22.8 percent of all the storage receptacles and was employed by 50.4 percent of the residents. Similarly, residents employed a combination of waste disposal methods which included burning, and dumping in the drains, river banks and on vacant plots. Methods of solid waste storage and disposal varied across the different residential areas of Ibadan municipality. It was established that despite the huge amount of money expended on the collection of solid waste during the exercise, only government-owned vans constituted less environmental health hazard.

It would assist in evaluating the success and failure of the monthly environmental sanitation exercise. It would also reveal to policy makers’ direction to which policy initiative should focus. Findings of the study could serve as a guide for the management of solid waste from similar exercises in countries of the developing world with similar socio-economic and environmental sanitation practices.

Presented in this paper are results of an investigation into solid waste management during monthly environmental sanitation exercise in Ibadan municipality, Nigeria. The study was an attempt at examining the different storage and disposal methods employed by households in the management of solid waste during the exercise. It also revealed what is committed financially into the collection and transportation of solid waste for final disposal during the exercise by government.

A systems perspective of waste management allows an integrated approach not only to the five basic functional elements of waste management itself (generation, reduction, collection, recycling, disposal), but to the problems arising at the interfaces with the management of energy, nature conservation, environmental protection, economic factors like unemployment and productivity, etc. This monograph separately describes present practices and the problems to be solved in each of the functional areas of waste management and at the important interfaces. Strategies for more efficient control are then proposed from a systems perspective. Systematic and objective means of solving problems become possible leading to optimal management and a positive contribution to economic development, not least through resource conservation. India is the particular context within which waste generation and management are discussed. In considering waste disposal techniques, special attention is given to sewage and radioactive wastes.

The commercial and residential refuse generated by Ellsworth Air Force Base, USA was characterized and analyzed for collection procedures, and the opportunities for increasing the amount of solid waste that could be recycled were evaluated.

Random loads of hauled solid waste (an average 3.0 US tons/load) from different waste streams of Ellsworth Air Force Base were sorted. The weight fraction of each category of recyclable material derived from the hand sorting operations was applied to the three years of mixed waste tonnage in order to estimate the tonnage of each recyclable category disposed of as refuse during each year. The assessment of the data obtained from three full calendar years focused on the mixed solid waste generated from commercial and residential areas such as offices, childcare, lodging, supermarkets, food service facilities, and others.

Over 2,500 tones of recycling opportunities were missed during the 1999‐2001 calendar years. The characterizations of the total weight produced from commercial and residential waste streams showed that recyclable material constituted 35.95 percent and 23.27 percent of refuse from the commercial and the residential areas, respectively. The amounts of total recyclable material as missed opportunities for recycling were found to be 1,728 tons and 715 tons from the commercial and residential areas.

In response to the findings, Ellsworth Air Force Base has implemented a number of strategies for increased recovery of recyclables from its solid waste streams.

Quantifying missed opportunities for recycling is a useful action in planning future recycling operations aimed at best solid waste management practices.

This study aims to examine whether or not residential properties closer to landfill sites have lower offer values by the developers. That is, by analyzing real estate data and landfill site locations, the study seeks to provide insights into whether properties situated closer to landfill sites tend to have a lower offer values than those located farther away.

The study is exploratory in nature, and a case study approach is applied. A landfill site named “Uruli Devachi” is selected in the region of Pune district, and data is collected from 102 developers selling residential projects within a radius of 15 km (about 9.32 mi). The gathered data is analyzed by using basic descriptive statistics, one-way ANOVA and ordinary least squares (OLS) regression. The OLS regression helps to determine whether there is a relationship between the distance of a residential property from a landfill site and its offer value.

The findings suggest that landfill sites have a detrimental impact on residential property offer values, with the negative impact increasing with proximity to a landfill site. The negative effect seems to vanish after over 10 km (about 6.21 mi). The developers provide extra facilities including a clubhouse, a children’s play area, a gym and a swimming pool in an effort to mitigate the negative effects of the landfill site on residential properties.

The findings of this study could have implications for property developers, real estate professionals and policymakers in understanding how landfill proximity might impact property offer values.

This study presents many novelties for the Indian housing market: the landfill sites do have a negative effect on the offer value of residential property; the closer the residential property to a landfill site, the higher the negative effect. Further, the developers try and mitigate the negative effect of landfill sites on residential properties by providing additional amenities such as a clubhouse, children’s play park, gym and swimming pool.

The chapter aims to evaluate the efficacy of stakeholder participation in the solid waste management system of Mauritius in view of providing a possible mechanism to attain the goals of a sustainable waste management framework.

The study employs qualitative indicators, namely, User Inclusivity and Producer Inclusivity of the Wasteaware Benchmark Indicators. Secondary data are used to conduct a critical and comprehensive analysis of the sub-indicators falling under each of the two main indicators to determine the overall compliance level with respect to stakeholder engagement of the waste management sector of Mauritius.

The results of the study show a LOW/MEDIUM compliance level for both User Inclusivity and Provider Inclusivity indicators, which indicates that improvement is required in the stakeholder engagement mechanism in Mauritius. The main weaknesses identified comprise of lack of an adequate legal framework with clear definition of waste types with regards to segregation, especially for non-hazardous wastes, low efficiency of sustainable waste management awareness campaigns and lack of inclusion of the informal sector. The main strengths identified consist of a proper bidding mechanism in place and a good level of equity in the provision of waste management services with respect to comingled waste collection. Suggested improvement areas include a revamping of the existing legal framework related to waste management to cater for higher inclusivity of all stakeholders together with including sustainable waste management topics in the formal education curriculum.

The User Inclusivity and Producer Inclusivity indicators were previously applied only to cities to measure the level of stakeholder participation, but this study has demonstrated that these indicators can also be adopted on a nation-wide level to evaluate stakeholder engagement. The use of these indicators together with secondary data presents a less time-consuming method to assess stakeholder participation in the waste sector, which can be particularly useful for Small Island Developing States.

The concept of sustainability has been gaining importance globally due to the growing environmental concerns and rising support from the nations to conserve the planet. Particularly for a country like India, this approach is highly relevant for combating the increasing stress on different sectors of the society due to the growing population. Solid waste management is an important sector that requires an immediate attention in the current context. Implementation of integrated sustainable waste management approach minimizes the waste and provides economic benefits, through best suitable method for managing the waste. In the present scenario, it is difficult for local bodies to apply this approach throughout the country due to diverse conditions and financial constraints. However this approach can be implemented through decentralization of solid waste management by the local bodies at a small scale. Technical institutes have a greater role to play in the society by nurturing the young minds about the need and ways to develop a sustainable society. The paper aims to discuss these issues.

The study area discussed in this paper is Jaypee University of Engineering and Technology situated on Agra-Mumbai national highway, Guna district, Madhya Pradesh, India. It covers an area of 125 acres and houses a population more than 3,000. The present work discusses about the development of strategic plan for sustainable waste management on the campus through the characterization and analysis of waste samples collected from academic buildings, hostels, mess, shopping complex and residential areas for beneficial utilization.

The study revealed that potential benefits such as biogas generation from organic waste, resource optimization through 3R concept (reduce, reuse and recycle) from paper, plastics, cardboard, glass, metals, etc. could be derived by adopting suitable waste management strategy.

The present work discusses the feasible options for the efficient utilization of the components of solid waste through integrated solid waste management system. The university with its diverse nature of wastes generated from academic buildings, hostels, mess, shopping complex and residential areas; provides a good opportunity to understand the options for sustainable waste management on the campus for wider applications.
