Despite the use of modern technologies that aim to reduce the environmental impact of manufacturing, industrial production still brings with it some negative phenomena. This mainly relates to the production of waste materials of various types, properties, volumes and also adverse effects on the environment.Most primary raw materials are transformed into waste, so it is essential to maximize the rational use of not only all input materials and energies but also secondary waste materials from production processes. This is especially important since the supply of primary raw materials is not unlimited. The use of waste as a secondary raw material is a beneficial phenomenon for the environment, leading to a reduction in dependence on imported raw materials, and above all, it eliminates the problem of its disposal.The Republic’s strategic goal is to gradually reduce the high raw material and energy intensity of industrial production using low-waste treatment technologies, higher utilization of secondary raw materials and implementation of environmental management such as Circular Economy. According to legislation, the use of waste is preferred to its disposal, with the emphasis being placed on preferential material utilization over other uses of waste.Recently, all developed nations have devoted much attention to the issues of waste management, and it must be emphasized that the solutions to waste management are in the interest of us all for the future and to the heritage, we leave for future generations.The article aims to analyze the possibilities of using waste materials from the production of iron in the construction industry and the possible effects on the environment.Keywords: Slag, construction industry, waste, circular economy
