Cost savings of contracting out refuse collection

The article discusses the possible cost savings of contracting out refuse collection in the Netherlands. According to foreign econometric studies, contracting out refuse collection leads to cost savings of approximately 20%. Our findings indicate that similar cost savings apply to the Netherlands. However, different production technologies apply to internal or external refuse collection. The Chow test, which examines whether the estimated coefficients on the explanatory variables are the same, reveals that different cost functions have to be estimated for the sub-samples. We show that the postulated cost savings can even be larger, when taking account of effects of different production technologies. Though significant cost savings exist on contracting out waste collection, households will not experience these cost savings on a one to one basis. Private refuse collection firms must pay VAT while public firms are exempted. At present the Dutch fiscal system hinders a more pronounced role for private refuse collection firms.Refuse collection, cost estimation, Chow stability test, pooling, VAT

Measuring the efficiency in Spanish municipal refuse collection services

The objective of this study is to analyse the technical or productive efficiency of the refuse collection services in 75 municipalities located in the Spanish region of Catalonia. The analysis has been carried out using various techniques. Firstly we have calculated a deterministic parametric frontier, then a stochastic parametric frontier, and finally, various non-parametric approaches (DEA and FDH). Concerning the results, these naturally differ according to the technique used to approach the frontier. Nevertheless, they have an appearance of solidity, at least with regard to the ordinal concordance among the indices of efficiency obtained by the different approaches, as is demonstrated by the statistical tests used. Finally, we have attempted to search for any relation existing between efficiency and the method (public or private) of managing the services. No significant relation was found between the type of management and efficiency indices- L'objectiu d'aquest estudi és analitzar l'eficiència tècnica o productiva dels serveis de recollida d'escombraries a 75 municipis de Catalunya. L'anàlisi s'ha portat a terme utilitzant varies tècniques. En primer lloc, hem calculat una frontera paramètrica determinística, després una frontera paramètrica estocàstica, i finalment, varies aproximacions no-paramètriques (DEA i FDH). Pel que fa als resultats, aquests naturalment difereixen en funció de la tècnica utilitzada per aproximar la frontera. No obstant això, guarden una aparença de solidesa, al menys pel que fa referència a la concordança ordinal entre els índexs d'eficiència obtinguts per les diferents aproximacions, com mostren els tests estadístics utilitzats. Finalment, hem intentat buscar si existeix alguna relació entre l'eficiència i el mètode (públic o privat) de gestionar els serveis, no trobant-se cap relació significativa entre el tipus de gestió i els índexs d'eficiència

Emissions pollutant from diesel, biodiesel and natural gas refuse collection vehicles in urban areas

Urban pollution is more and more concern due to human health implications. In that way, emissions pollutant from commercial vehicles which move daily at fixed itineraries such as, buses and refuse collection vehicles must be monitored. In this study we have aimed to show the results of the test made on refuse collection vehicles, in real conditions, with regard to their energy consumption and emissions pollutant. A comparative study is carried out with regard to CO, HC, NOx, PM and greenhouse gas emissions, in respect of two types of engine with three different fuels. The fuels analyzed are diesel, biodiesel (B50 and B100) and compressed natural gas (CNG)

Caddo Ceramic Sherd Assemblage from a Hearth Feature at the Cherokee Lake Site (41RK132) in Rusk County, Texas

There is a collection of plain and decorated ceramic sherds in the Gregg County Historical Museum from a feature, described as either a fire pit or a hearth, excavated by Buddy Calvin Jones in March 1956 at the Cherokee Lake site (41RK132) on Toawichi Creek in northern Rusk County, Texas. This assemblage is discussed in this article. The Cherokee Lake site is best known for its early 18th century Nadaco Caddo component, but it also has a Middle Caddo period (ca. A.D. 1200–1400) component. In Jones’ discussion of work he conducted at the Cherokee Lake site, he mentions the excavation of an Historic Caddo burial as well as a large “refuse pit” of prehistoric age, both in Area A of the site. The excavation of a fire pit or hearth in any area at the site is not mentioned by Jones, but it seems likely that the “fire pit/hearth” may be the same feature as the aforementioned refuse pit. In any case, this “fire pit/hearth” feature at the Cherokee Lake site contained a considerable number of plain and decorated ceramic sherds, as did the “refuse pit.” According to Jones, the refuse pit had “Hickory Engraved, Dunkin Incised, variant types, unidentified types of punctated and incised wares,” as well as a small Bullard Brushed jar, a fragment of a second Bullard Brushed jar, both from the upper part of the pit, and fragments of a plain bowl from the floor of the pit

Similar problems, different solutions: Comparing refuse collection in the Netherlands and Spain

Local public service provision can vary greatly because of differences in institutional arrangements, public service markets, and national traditions regarding government intervention. In this paper we compare the procedures adopted by the local governments of the Netherlands and Spain in arranging for the provision of solid waste collection. We find that Spain faces a consolidation problem, opting more frequently to implement policies of privatization and cooperation, at the expense of competition. By contrast, the Netherlands has, on average, larger municipalities, resorting somewhat less to privatization and cooperation, and more to competition. The two options - cooperation and competition - have their merits when striving to strike a balance between transaction costs and scale economies. The choices made in organizational reform seem to be related to several factors, among which the nature of the political system and the size of municipalities appear to be relevant.Local governments, contracting-out, privatization,inter-municipal cooperation.

Is green a grey area? Sustainability and inclusivity; the ageing population and recycling

There are growing pressures (political, legislative and environmental) to increase material recovery through recycling. There are two basic recycling schemes in the UK; kerbside and bring-site schemes. With current kerbside schemes, when a householder becomes unable, through age, illness or disability, to physically move their waste containers (bins,boxes or bags) onto the pavement for collection, the refuse collection service provider will enter the property premises, take the containers out to the refuse collection vehicle (RCV), empty them before returning them to the starting point. Obviously, with bring sites, people travel to the site and place the recycling in the banks themselves. With an ageing population, increasing numbers of older people are requiring specialist recycling services. These are likely to become more time consuming and costly as household numbers increase. Bring sites have obvious limitations for older people with their limited mobility and reduce strength. To date little or no previous research has been undertaken about barriers to recycling for older people and the implications to waste management providers of an ageing population. This paper describes initial work beginning to assess this problem within Lab4Living at Sheffield Hallam University (SHU).In this positioning paper, we examine literature regarding barriers to recycling and relationships with age. We outline a hypothetical scenario for the impact of the ageing population on future material recovery rates in the UK, present the initial results of a survey and we describe the potential role that design can play to eliminate these barriers and our activities within this area in our project; ‘The Grey Areas of Green Design’

The institutional choice of refuse collection: Determining variables in the Netherlands

General empirical evidence suggests that contracting out refuse collection results in a cost decrease in the order of 20%. However, although the method of contracting out refuse collection has become more popular, it is still less common than in-house provision. This paper investigates the reasons behind this phenomenon. Recently, L?pez-de-Silanes et al. (1997) tried to explain the reservedness of local authorities towards contracting out with US-data and show that political patronage is an important explanation. In this article we give such an empirical assessment using Dutch data. We base our empirical research on the combination of the theories around efficiency, interest group influence and ideology. To test these theories we model the choice between private and public provision of refuse collection on the one hand side and the choice between in-house and out-house provision on the other side. Data are available for nearly all Dutch municipalities. A most striking conclusion is that nearly all political parties in the Netherlands do have a preference for public and in-house provision of refuse collection. We find only modest evidence for the hypothesis that a high level of real estate tax (proxy for the soundness of municipal financial affairs, the efficiency argument) or a low leve

The impact of compulsory competitive tendering on refuse collection services

Compulsory competitive tendering (CCT) of blue-collar services such as refuse collection and street cleaning was introduced in the UK by the Local Government Act 1988. This law, imposed by central government, obliged elected local authorities to expose specific services to competitive tendering at fixed intervals and subject to national guidelines. Whilst the issue of competitive tendering of public services has generated a substantial literature over recent years (see Domberger and Rimmer (1994) for a review), there have been relatively few studies of compulsory competitive tendering.2 This paper uses a dataset on refuse collection costs and services for the 365 English local authorities over the period 1984-94. It follows on from Szymanski and Wilkins (1993) who analysed the same database using data up until 1988

Public vs private production efficiency: A theoretical and empirical comparison

The relative efficiency of private and public production of a public service (in particular households' refuse collection) is studied using the theory of property rights and the economic theory of bureaucracy. Both kinds of institutional organization of production result in inefficiencies if realistic conditions are considered. The empirical analysis of refuse collection of 103 Swiss cities shows evidence that private production may be more efficient. If refuse collection were turned over to private enterprise on the basis of some such evidence, the government's task does not end but rather is shifted, only. It has to find ways and means to set the conditions such that private producers function efficiently in the long run. In particular, it must insure that competitive pressure on costs persists
