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.
