  • In this subclass the following terms or expressions are added 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
