 abstract={The article presents full mineralogical and chemical characteristics as well as physical and mechanical properties of mineral fibre (basalt, glass and ceramic) waste formed in the process of insulating materials' dismantling. On the basis of chemical investigations (using an electrone microprobe), X-ray and OTA analyses, changes in microstructure, chemical and phase compositions were determined after insulating materials had been used. The examined fibres have been ranked in the following order with respect to the increasing degree of changes: basalt, glass and ceramic. In basalt and glass fibres, changes occur only in chemical composition of individual fibres. Use of ceramic fibres leads to formation of new phases: mullite and cristobalite. Comparison of physical, mechanical and chemical properties of mineral fibre waste with those of asbestos (completely different) must result in different technological characteristics, including respirability, which in the case of mineral fibre is less aggressive in terms of biological effect on a human organism. It cannot be excluded, however, that the increased respirability (signalled in the literature) ofcertain types of ceramic fibres partially results from a supporting role played by chemically different secondary fibres formed in devitrification process. In the case ofceramic fibres examined by the author these are newphase fibres, easily separable from each other at higher temperatures.},
