The recycling of metal waste and scrap is an essential component of a circular economy, which is predicated on the principles of reducing waste and consumption of resources through the reuse and recycling of materials. However, it is not always possible to process the metal while maintaining its chemical composition and producing high-quality ingots without complicating the technological process and incurring excessive costs. From this point of view, electroslag remelting can be an effective technology for recycling alloyed steel and nickel alloys to produce a high-quality material with reduced environmental impact and minimized toxic emissions. Modern two-circuit ESR technology with a current supplying mould significantly reduces the requirements for the geometry of the consumable electrode and greatly improves the ability to control the thermal processes taking place in the slag and metal bath. The research conducted has demonstrated the ability to effectively recycle various types of metal scrap, from used small tools to nickel alloy fragments, while preserving their chemical composition and producing quality ingots. The experiments also showed significant potential for processing metal chips and other similar metal wastes with production of quality ingots. The presentation reviews the technological aspects and the results of a series of studies on the recycling of various types of alloy steel and nickel alloy waste and scrap using the current supplying mould and two-circuit electroslag remelting technology.
