Regenerative Energie
Sewage Sludge consists of valuable compounds such as nutrients as well as harmful substances e.g. heavy metals. For sludges with a low pollutant concentration, utilization in agriculture is the best option for sludge reuse.
Highly polluted sludges are not suitable for agricultural reuse, but carbon recycling is possible by using mechanical (disintegration) or chemical pre-treatment with anaerobic degradation processes. The other important valuable compound in sludge is phosphorus which is a limited resource on earth. Recycling options for phosphorus are also describe in the paper. A safe disposal of the residues can be achieved by using incineration.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
