DISPOSAL OF SOLID WASTE NOT OTHERWISE PROVIDED FOR

Introduced: January 1980

Description

B09B encompasses disposal methods and systems for solid waste that do not fall within more specific waste treatment classifications. This subclass covers general-purpose waste disposal techniques including landfilling, incineration, and other terminal treatment processes for mixed or unclassified waste streams. It serves as a residual category for waste management inventions that lack a dedicated classification elsewhere in the IPC system, particularly where the waste composition or disposal method does not align with specialized subclasses like B09C (reclamation of contaminated soil) or sector-specific waste handling classes.

Of 5 combined children, 3 exist in both systems.

1 codes are CPC-only extensions, 1 exist only in IPC.

Note: 1 CPC extensions are marked as secondary classification only.

IPC defines codes here since 1980.
