Abstract	Utilization of different kind of waste in reclamation of disturbed terrains is main a part of Circular Economy concept. The use of the waste gives an opportunity to reduce the amount of generated waste and the areas disturbed by their disposal. All of it is key point for the conservation of environmental. Bottom ash utilization like a soil improver can reduse the amount of valuable waste with a hight content of organic matter and essential nutrients. This study aims to analise the possibilities for the use of bottom ash from biomass (straw) combustion for the reclamation of strongly acidic mine soils were studied. The ash shows hight potential for use on acid soils due the alkaline pH, high content of organic matter and nutrients - total N, P2O5, K2O. Vegetation experiment with different bottom ash content is performed to be proven this possibility. The experiment shows that the addition of bottom ash leads to the neutralization of strongly acidic mine soils, but at the same time leads to salinization with an increase in the percentage of bottom ash. The optimum quantity of bottom ash for use is 5% of the amount of soil.
