The relevance of the study is due to the need to identify the problems, features and consequences of strategic transformations in the metallurgical industry of Ukraine in the context of reviewing the circular process of organization of the economy, where the blast furnace, open-hearth and rolling production waste are of a high potential. The reuse of metallurgical waste has a number of economic advantages in terms of the chemical composition of the product life cycle. Blast furnace slag is suitable as a raw material in cement production and can be used as fillers in the construction of roads, hydraulic and environmental facilities, during reclamation works, etc. Agriculture actively uses slag as a fertilizer that contains potassium, magnesium, phosphorus, magnesium, boron – as an additive that reduces soil acidity. Currently, all slag can be processed into fertilizers or building materials. The economic effect of the use of slag in construction is accounted for in the relatively low cost of products, improvement of the quality and durability of the structures. The main positive consequences of smartization of the metallurgical industry are increase of its resource efficiency and environmental friendliness, negative – the low level of blast furnace slag use in various sectors of the economy compared to the experience of developed countries, an insufficiently developed legal framework. The mechanism of state management of the use of secondary raw materials, especially metallurgical origin, in conditions of shortage of energy resources and the intensive use of non-renewable natural resources remains an important scientific problem and requires further research.
