Legal framework - initial situation for sewage sludge in Germany
The Sewage Sludge Ordinance (AbfKlärV) of October 2017
In order to improve sustainable environmental and resource protection, the ordinance on the reorganisation of sewage sludge utilisation tightens the previously effective requirements on the land application of sewage sludge. The Sewage Sludge Ordinance (AbfKlärV), which entered into force on 3 October 2017, is thus leading to a reorientation of sewage sludge utilisation in Germany.
In order to reduce environmental pollution, the new sewage sludge ordinance no longer allows sewage sludge to be applied to agricultural land so easily. Central elements of this ordinance are, among others, the requirements for the recovery of phosphorus from sewage sludge and sewage sludge incineration ashes.
The amendments to the Fertilizer Act in 2017 are intended to reduce environmental pollution resulting from the spreading of sewage sludge containing nitrogen and phosphate and to increase fertilizer efficiency. The limitation of nitrogen loads to 170 kg N/ha*a, the competition between different fertilizers such as fermentation residues, liquid manure and sewage sludge, extended blocking periods for the application of fertilizers and the new requirements for the degradability of synthetic polymers will further complicate the current practice of sewage sludge disposal in the short term.
