The authors present a unique possibility of utilizing hitherto unused and difficult-to-store types of waste such as dust generated during the extraction and treatment of a natural stone, and still difficult to recycle part of construction and demolition waste – residual mineral inert material. Stone dust mixed with residual mineral inert material, water, and binders in various proportions formed five types of mixtures which were transformed into manufactured aggregates using hyper-pressing. The properties of these manufactured aggregates – resistance to crushing and bulk density – presented on laboratory-based samples were similar to those of natural aggregates. The production of manufactured aggregates, the processing of unused types of construction and demolition waste, together with stone dust, fully comply with the rules of circular economics. The availability of stone dust has been checked based on data obtained by personally interviewing the authors in the quarries of the pilot regions of South Bohemia and Pilsen. Data on the amount of construction and demolition waste produced were obtained from the publicly available database of produced construction and demolition waste – Waste Management Information System (ISOH).
