Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:


discarding, e.g. dumping, or destroying of waste or its transformation into something useful or harmless;

Solid waste

ncludes waste which, although it has liquid content, is for practical purposes handled as solid

Dumping solid waste
Definition statement

This place covers:

Disposing of solid waste by means of dumping, either as bulk material or as

discrete elements of stabilized and/or packaged waste. Dumping may be

within underground cavities.

Example: US-A1-2003/053865


{Sea dumping (disposal of radioactively contaminated material by storage under water G21F 9/24)}
Definition statement

This place covers:

Dumping solid waste on or into the seabed.

Example: BE-A5-1015677


{Covering of dumping sites}
Definition statement

This place covers:

Covering dumped waste, the cover means being applied to the top surface of the dumped waste.

Example: US-A1-2002/067953


{Shafts or wells in waste dumps}
Definition statement

This place covers:

Shafts or wells and providing these in waste dumps, the shafts or wells being manufactured before, during or after dumping the solid waste.
