ABSTRACT
Classic environmental impact analysis is usually used in order to assess the whole life cycle on the basis of actual real data. In the process of coal combustion all steps from cradle to grave should be included, which means from coal mine to the combustion chamber. This analysis is relatively easy if all necessary input data is available. The evaluation of potential environmental impact of the coal itself is much more problematic. Some part of environmental impact is associated with fuel properties like composition and concentration of specific compounds, and could be predicted for instance on the basis of the stoichiometric analysis. However, some part of emission is associated with specification of installation where combustion process takes place which is much more difficult to predict. Methodology of assessment of potential environmental effect of the coal itself is proposed in the manuscript. The evaluation is made using CML2001 methodology in 6 major impact categories: human health, eutrophication, acidification, abiotic depletion, climate change and photo-oxidant formation. The new indicator of coal quality, which is introduced in different major impact categories, is defined in the manuscript. The indicator could be treated as a measure of potential nvironmental impact of the coal, which could be used for assessment of balancing the environmental costs associated with the activities at the coal mine.
