Cost efficiency in the management of solid urban waste
Section snippets
Topic framework and research hypothesis
Western governments often link competitiveness in public-service management to the opening-up of markets and privatisation. Actually, if we analyse what international literature has to say, as well as the results of some empirical studies, the problem seems to be more complex; so much so that at the present time it is almost impossible to take the side of supporters of market supremacy, or conversely those who hold faith in various forms of State intervention. In reality there appear to be more
Background theories
The first works on waste cost go back to the end of the 70s. At that time waste management was still seen in terms of collection and disposal in a landfill. From then on, studies began to examine the relationship between costs and certain variables, especially market types and size of catchment area.
Savas (1977) was the first to reveal a correlation between collection costs and population size. In order to exploit economies of scale, he considered 50,000 inhabitants to be the optimal number. In
Empirical study
This section compares the potential determinants of costs of waste management and includes facts and figures for each one. In particular, Section 3.1 analyses the relevance of technology in determining waste management costs; Section 3.2 focuses on population related issues (population density and area extension) as potential explanatory factors. Finally, Section 3.3 considers service delivery arrangements as a cost determinant.
There is evidence to show that costs are mainly determined by
Conclusion
The results of this study would appear to confirm that there is a clear correlation between waste management technique and overall financial-environmental performance. Generally speaking, the choice should fall on the more “industrial” and integrated systems, based on large-capacity recovery plants dedicated to separated waste. On the contrary, systems in which a number of waste firms continue to exploit the “collection-landfill” model need to be phased out.
On the other hand, no correlation was
