The article indicates the issue of revitalization of urban areas on the example of the former provincial city. Particular attention was paid to threats to the natural environment caused by difficulties in managing construction waste arising during this process. During the research work on waste demolition material from repairs and reconstruction of buildings, ceramic construction waste was selected. These materials were crushed and dust was generated from them. The purpose of the work was to study the activity indicator, i.e. the research that is carried out for dusts obtained, e.g. in metallurgical processes. The parameter described was a determinant of the possibility of using dust as a recyclable cement substitute in concretes and mortars. The research material was ceramic waste. The waste was picked up from the landfill and sorted. Wastes of red ceramics were isolated in the form of damaged bricks, hollow bricks and roof tiles. Dust was produced from such prepared waste. The research methodology was carried out in accordance with the standard PN-EN 450-1:2012. The activity index of crushed ceramic dust after 28 days was 60.9%, after 90 days 72%. Given the slight change in the strength parameters of mortars and special considerations of the necessity of waste utilization, the described ceramic dust recycling is considered as a solution possible to implement in the production of mortars and non-structural concretes. Introduction of the results of these works to market activities may contribute to the reduction of waste deposited on landfills.
