Residual products of the chemical or allied industries, not elsewhere specified or included; sewage sludge

HS v2017 Code: 382520

About residual products of the chemical or allied industries, not elsewhere specified or included; sewage sludge

HS code 382520 covers a diverse range of residual products from the chemical and allied industries that do not fit into other more specific categories. This includes materials such as sewage sludge, which are byproducts of various industrial and municipal processes. While these materials may not have a high commercial value on their own, they play an important role in waste management and the circular economy, as they can be repurposed or treated for further use.

Production process

The production techniques for the materials covered under HS code 382520 vary widely depending on the specific type of residual product. Sewage sludge, for example, is typically generated through the treatment of wastewater in municipal or industrial facilities. The sludge is then dewatered, stabilized, and may undergo further processing such as composting or thermal treatment before being disposed of or utilized.

Production inputs

The main inputs required for the industries covered by HS code 382520 are the various waste streams and byproducts generated by other manufacturing and municipal processes. This can include wastewater, industrial process residues, and other materials that are not the primary output of a particular industry. The specific equipment and facilities needed will depend on the type of residual product being handled, such as sludge dewatering equipment, composting facilities, or thermal treatment systems.

Production outputs

The outputs of the industries covered by HS code 382520 can include a wide range of materials, depending on the specific residual products being processed. These may include treated sewage sludge for use as a soil amendment, recovered materials for recycling or energy recovery, and other products that can be reintegrated into industrial or municipal processes. The outputs of this industry may be consumed by other industries, such as 440122 Sawdust and wood waste and scrap, whether or not agglomerated in logs, briquettes, pellets or similar forms, 271091 Waste oils, or 310290 Mineral or chemical fertilizers, nitrogenous, including mixtures not specified elsewhere.
