Ash and residue (except from the manufacture of iron or steel), containing metals or metallic compounds, except precious metals

cpc code 39320 covers the classification of ash and residue containing metals or metallic compounds, excluding those from the manufacture of iron or steel, as well as those containing precious metals. This industry plays a crucial role in the broader waste management and recycling ecosystem, as it enables the recovery and reuse of valuable materials that would otherwise be discarded. By extracting and processing these materials, the industry contributes to the circular economy and helps reduce the environmental impact of waste disposal.

The main production techniques used in this industry involve the collection, sorting, and processing of the ash and residue materials. This typically includes mechanical separation methods, such as screening and sorting, to isolate the metal-containing fractions. Further processing may involve thermal or chemical treatments to extract and purify the metal compounds for subsequent use in other industries.

The primary inputs required for this industry include the ash and residue materials themselves, which are sourced from various industrial and commercial activities. Additionally, the industry relies on specialized equipment and machinery for the collection, sorting, and processing of the materials, as well as energy sources and chemical reagents used in the extraction and purification processes.

The main outputs of this industry are the recovered metal compounds and metallic materials, which can be used as feedstock for a variety of downstream industries, such as 39330 (Slag, dross (except granulated slag), scalings and other waste from the manufacture of iron or steel), 38120 Waste and scrap of precious metal or of metal clad with precious metal, and 38130 Ash and residues containing metals or metallic compounds. The industry also generates waste streams that may require further processing or disposal, depending on their composition and environmental regulations.
