Abstract
The article analyses the application of two management systems - REACH directive and ISO 14040 (Life Cycle Assessment - LCA) with reference to the technological process as well as by-products of mineral wool production. It characterizes basic differences between the norms discussed, i.e. the strict formalization of REACH, which results in the analysis being conducted according to a precisely defined scheme, or the subjective character of LCA, which makes it possible to take into account the most important environmental aspects pertaining to the entire life cycle of a particular product. The discussion provides a basis for formulating the general conclusion that the classification criteria encompassed by REACH regulations do not allow for a complex analysis of the negative environmental impact of a particular substance (preparation, product) and should be complemented with elements of LCA analysis.
