Note(s)

  1. This subclass covers only single or combined, e.g. multistage, operations not fully classifiable in a single other subclass. [3]
  2. 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; [3]
    • "solid waste" includes waste which, although it has liquid content, is for practical purposes handled as solid. [3]
