B09B
DISPOSAL OF SOLID WASTE NOT OTHERWISE PROVIDED FOR [2024-01]
NOTES

  • This subclass covers only single or combined operations, e.g. multistage operations, not fully classifiable in a single other subclass.
  • In this subclass, the following terms or expressions are used with the meanings indicated:
    • "disposal" means the discarding, e.g. dumping, or destroying of waste or its transformation into something useful or harmless;
    • "solid waste" includes waste which, although it has liquid content, is for practical purposes handled as solid.
  • In this subclass, it is desirable to add the indexing codes of group {B09B 2101/00}.
