HS v2022 Code: 262021

About slag, ash and residues; (not from the manufacture of iron or steel), containing mainly lead; leaded gasoline sludges and leaded anti-knock compound sludges

HS code 262021 covers a range of slag, ash, and residues that contain primarily lead. This industry plays a crucial role in the management and recycling of hazardous waste materials, particularly those generated by the automotive and petroleum industries. The proper handling and processing of these materials are essential for environmental protection and resource conservation within the broader economy.

Production process

The main production techniques involved in this industry include the collection, sorting, and processing of the slag, ash, and residues. This often involves specialized treatment methods, such as smelting or chemical processing, to extract and recover the lead and other valuable materials. The goal is to safely and efficiently process these hazardous materials while minimizing environmental impact.

Production inputs

The primary inputs for this industry are the slag, ash, and residues containing lead, which are typically generated as byproducts or waste from other industrial processes. This includes leaded gasoline sludges and leaded anti-knock compound sludges, as well as other lead-containing materials. The industry also requires specialized equipment and facilities for the safe handling, transportation, and processing of these hazardous materials.

Production outputs

The main outputs of this industry are the recovered lead and other valuable materials extracted from the slag, ash, and residues. These outputs can be used as raw materials in various 260300 Lead ores and concentrates, 780110 Unwrought lead; refined, and other related industries. The industry also generates processed waste materials that may require further specialized disposal or treatment to minimize environmental risks.
