Abstract
Waterproof waste wood contains a series of chemicals, especially chromium,
copper and arsenic, which can be hazardous to human health and the natural
environment in concentrated quantities. In this welfare economic analysis the
economic and environmental consequences of four methods of processing
impregnated waste wood are considered and compared: deposition, incineration,
gasification and an extraction process. The quantity of impregnated waste wood
is not a limiting factor for the individual method. The analysis includes both the
socio-economic and the environmental consequences of applying these methods.
The results of the analysis show that incineration and gasification are the
cheapest wood processing methods in a welfare economic perspective. The
reason is that both methods produce heat and thereby avoid the use of other more
polluting fuels. Deposition is quite expensive, and it neither recycles nor uses the
energy in the wood. If one only looks at the direct costs of the processes, and
does not estimate and include the value of the environmental consequences, the
differences between the methods are smaller. The basis for the article is a report
by the authors for The Danish Environmental Protection Agency. The authors
would like to express their gratitude to the agency for funding.
Keywords: impregnated waste wood, welfare economic assessment.
