Hildesheim gets a new sewage sludge system: Focus on phosphorus recovery!
Hildesheim, Deutschland - In Hildesheim, a new lighthouse is built in the sewage sludge recycling! The municipal nutrient recovery Niedersachsen GmbH (KNRN) has commissioned the renowned plant farmers Andritz to build a mono fuel system. According to euwid Wasser, this project aims to ensure reliable sewage slewing and phosphorus to regain the resulting sewage sludge ash-a hot topic in resource conservation.
The system is located in the Hildesheim port and can process up to 14 tons of sewage sludge original substance per hour. This means that it can master around 33,500 tons of sewage sludge dry mass annually. The approval for the construction was granted last autumn and also includes a sewage sludge storage, drying measures and an envelope for waste.
sustainability in focus
Particular attention is paid to the recovery of phosphorus, which plays a crucial role in fertilizers. In view of limited phosphorus and increasing demand from the growing world population, recovery is a requirement of the hour. The new sewage sludge regulation determines for the first time comprehensive requirements for phosphorus recovery, such as Klimaschutz municipality From the beginning of 2029, systems with more than 100,000 inhabitants will actively regain phosphorus to meet the requirements.
The system in Hildesheim will also play a crucial role in the local energy system: The steam generated from the combustion is used for electricity production for the public network and to provide heat for the local district heating network. An environmentally friendly disposal is sought in accordance with the requirements of the sewage sludge ordinance (DänflAmV).
a strategic decision
The decision to invest in a mono fuel could also bring economic benefits in the long term. In view of the increasing prices for phosphate fertilizers, which rose by 60% in 2021 before the Ukraine decline, the safe recovery from sewage sludge becomes all the more significant. Not only for the environment, but also for agriculture. While about 20% of the municipal sewage sludge in Germany was used in agriculture in 2019, energy generation and the exploitation as secondary fuel is another important option.
summarized, the mono fuel in Hildesheim not only offered a solution to the sewage sludge problem, but also a direct contribution to resource conservation and energy supply in the region. The commissioning of this promising facility is planned for December 2027 - and the anticipation for this environmentally friendly innovation is growing.
