Slag, dross, scalings and other waste from the manufacture of iron or steel

CPC v2.1 Code: 39310

About slag, dross, scalings and other waste from the manufacture of iron or steel

cpc code 39310 covers the waste products generated during the manufacturing of iron and steel. These waste materials, including slag, dross, and scalings, are a significant byproduct of the steel industry, which is a crucial component of the global economy. The proper management and utilization of these waste streams are essential for the sustainability and efficiency of the steel production process.

Production process

The production of slag, dross, and scalings occurs as a natural consequence of the steelmaking process. During the smelting and refining of iron ore, impurities and other unwanted materials are separated from the molten steel, forming a layer of slag on the surface. This slag is then skimmed off and allowed to cool, resulting in the solid waste products covered under cpc code 39310. The specific techniques used to handle and process these waste materials can vary depending on the steel production facility and the intended use or disposal method.

Production inputs

The primary inputs required for the generation of cpc code 39310 materials are the raw materials used in the steel manufacturing process, such as iron ore, coal, and limestone. Additionally, the production of these waste products requires the use of various furnaces, smelters, and other specialized equipment used in the steelmaking industry. The efficient operation and maintenance of these production facilities are crucial for the generation of consistent and high-quality slag, dross, and scalings.

Production outputs

The main outputs of cpc code 39310 are the slag, dross, and scalings generated during the steel production process. These waste materials can be further processed and utilized in a variety of applications, such as 39320 (Ash and residues (except from the manufacture of iron or steel), containing metals or metallic compounds) for the recovery of valuable metals, 23990 Other non-metallic mineral products n.e.c. for use in construction materials, or 38120 Hazardous waste collection for proper disposal and environmental management.
