The regional allocation is based on the location of the waste water treatment plant (WWTP).
1: No multiple responses.
2: Multiple responses possible.
3: Pursuant to the German Sewage Sludge Ordinance (AbfKlärV), as amended.
4: Utilisation in or on soil used for agriculture.
5: For example, recultivation.
6: This only includes plants that have humified or composted quantities themselves in the current reporting year or have transferred quantities to other plants for humification and composting.
The quantities may also have been used to produce mixtures of sewage sludge and other materials under the Fertiliser Ordinance (Düngemittelverordnung), as amended.
7: For example in sewage sludge incineration plants or via pyrolysis, or gasification, low temperature conversion LTC (LTC) and
hydrothermal carbonisation HTC (HTC). Quantities that are incinerated with excess oxygen, for example in fluidised bed, grate and rotary firing systems, are also included.
8: For example in coal-fired power plants, coal upgrading facilities, cement plants, waste incineration plants and in other industrial combustion plants such as paper mills and wood-fired power plants,
even if the exact thermal co-treatment is not known.
9: This includes the transfer of quantities where further disposal is unknown.
