In the present paper, the validity of the waste hierarchy for treatment of solid waste is tested. This is done by using the tool life cycle assessment on recycling, incineration with heat recovery and landfilling of recyclable waste for Swedish conditions. A waste hierarchy suggesting the environmental preference of recycling over incineration over landfilling is found to be valid as a rule of thumb. There are however assumptions and value choices that can be made that make landfilling more preferable. This is the case for some waste fractions and for some of the environmental impacts studied when only a limited time period is considered. When transportation of waste by passenger car from the households is assumed for the other treatment options but not for landfilling, landfilling also gains in preference in some cases. The paper concludes that assumptions made including value choices with ethical aspects are of importance when ranking waste treatment options. Uncertainties related to the assessment of toxicological impacts can also influence the conclusions.
