Sewage sludge disaster in Dammbach: state road closed!

Sewage sludge disaster in Dammbach: state road closed!

In a remarkable incident, an eleven-kilometer-long trail of sewage sludge was discovered on State Road 2317 near Dammbach in Lower Franconia. This discovery occurred on Thursday night, whereupon police immediately closed the road. The closure was necessary due to the roadway being heavily contaminated and classified as dangerous. The Aschaffenburg district fire inspection describes the road as “slippery and extremely dangerous” and warns of possible dangers to road traffic.

The police have already started an investigation and are actively looking for the person who caused this mud trail. It is currently being investigated whether the sewage sludge was spread on the street due to a technical defect or possibly as an intentional environmental crime. Before the clean-up operation, there was a car accident nearby, and police are investigating whether there is a connection between the two incidents. The road closure is expected to last until midday while investigations continue. Witnesses are asked to contact police to provide further information.

Background on sewage sludge disposal

The problem with sewage sludge is not new. According to information from the Federal Environment Agency, sewage treatment plants deal with the purification of wastewater in various treatment stages, which creates sewage sludge. This sludge can contain a variety of contaminants, including heavy metals, organic contaminants and even drug residues. The big challenge is that many wastewater treatment plant operators are increasingly moving away from the direct agricultural use of sewage sludge and moving towards thermal disposal.

The effects of the 2017 Sewage Sludge Ordinance are particularly important in this context. Since then, stricter limits have applied to sewage sludge that can be used as fertilizer. Larger sewage treatment plants are obliged until 2029 or 2032 to only use their sewage sludge for soil purposes under certain conditions. Particular attention is also paid to phosphorus recovery, which is required for sewage sludge with correspondingly high phosphorus contents. Innovative technologies to recover phosphorus from sewage sludge and ash are currently being developed, showing that disposal practices in Germany are undergoing change.

The goal of the Federal Environment Agency is environmentally friendly sewage sludge disposal that is both resource-efficient and sustainable. It is essential that all stakeholders, from wastewater treatment plant operators to waste management companies, work closely together to overcome these challenges. In this context, the Federal Environment Agency has published a brochure that offers insights into the current situation and future developments in sewage sludge treatment.

If the investigations into the sewage sludge trail in Dammbach produce a result and those responsible are found, this may also have an impact on the discussions about the safe and environmentally friendly disposal of sewage sludge in Germany, which must be conducted on an ongoing basis.
