| Deponiebasisabdichtung | landfill base sealing | |
| Deponiebasisabdichtung | landfill base sealing (Sealing of a landfill with a relatively impermeable barrier designed to keep leachate inside. Liner materials include plastic and dense clay) | |
| Deponiebetreiber | site operator | |
| Deponieboden | landfill soil | |
| Deponiedrainageschicht | gas drainage layer | |
| Deponieentgasung | landfill degasification | |
| Deponieentgasung | landfill degasification (Landfill gas is highly dangerous as methane is highly explosive; therefore it must be controlled at all operational landfill sites, whether by active or passive ventilation or both especially in the case of deep sites. There exist venting systems for shallow and deep sites respectively) | |
| Deponieform | morphology of the landfill waste | |
| Deponiegas | landfill gas (Landfill gas is generated in landfill sites by the anaerobic decomposition of domestic refuse (municipal solid waste). It consists of a mixture of gases and is colourless with an offensive odour due to the traces of organosulphur compounds. Aside for its unpleasantness, it is highly dangerous as methane is explosive in concentrations in air between 5 per cent, the Lower Explosive Limit (LEL), and the Upper Explosive Limit (UEL) of 15 per cent. Landfill gas must be controlled at all operational landfill sites, whether actively or passively vented or both especially in the case of deep sites) | |
| Deponiegasüberwachung | gas control | |
| Deponieklasse | class of landfill | |
| Deponiekörper | landfill body | |
| Deponienabfall | waste for landfill | |
| Deponierung | landfill | |
| Deponiesickerwasser | landfill leachate (Liquid that has seeped through solid waste in a landfill and has extracted soluble dissolved or suspended materials in the process) | |
| Deponiesickerwasser | leachate | |
| Deponiestandort | dump site | |
| Deponiestandort | dumpsite | |
| Deponiestandort | landfill site | |
| Deponieuntergrund | underground dump |
