1. Three Levels of Information

The Level 3 texts correspond to the full text of the Life Cycle Assessment
 "LCA of thermal treatment of waste streams in cement clinker kilns in Belgium Comparison to alternative treatment options" a report published in October 2007 by TNO (the Netherlands Organisation for Applied Scientific Research).

The Level 1 is a short summary for non-expert readers of the above assessment and the Level 2 a more detailed summary. Because these summaries are directed to the general public, the results of the environmental comparison are presented separately for each type of environmental impact, in accordance with ISO 14044 – the international standard that specifies requirements and provides guidelines for Life Cycle Assessments.

For experts and decision makers weighed results expressed in artificial monetary terms and underlying assumptions are available in the full report presented in Level 3.

2. Rationale – change in taxation on secondary fuels

The context of the study is the contestation by Febelcem of a decree of the Flemish Region (decreet van 22 december 2006 houdende bepalingen tot begeleiding van de begroting 2007).

This decree modified the taxation rate on waste according to their final treatment. For the first time the tax on waste going to co-incineration is equal to the tax on waste going to incineration plants. From the Febelcem point of view this is in contradiction with the European legislation (waste hierarchy: co-incineration is a recovery operation and has to be preferred to incineration, that is a disposal operation). In addition a tax should be an incentive that favours the best treatment (from an environmental point of view).

However, the Flemish Region (OVAM) argued that incineration and co-incineration present similar environmental impacts (argumentation principally based on the fact that both waste treatment are submit to the same directive on incineration and co-incineration (2000/76/CE)).

The study has been commissioned in order to tackle this controversy and now proves that co-incineration is to be preferred to incineration.

FEBELCEM now feels that the Flemish Region has to revise the taxation rates.

3. Publication History

The Life Cycle Assessment was conducted at the request of Febelcem.
