The energetic utilization of organic waste and renewable raw materials in anaerobic digestion plants (AD plants) as a climate neutral biogas has increased considerably within the last few years.
In the existing AD plants a completely good mixing of the bioreactors is rarely found. Furthermore the formation of zones without mixing (“dead zones”), sedimentation areas, short circuit flows and floating layers are, possible. These deficits adapt because stirring aggregates used in biogas plants often show unfavourable geometries, are not placed correctly in the AD tank, or are unsuitable for the type of application.
This has the consequence that available reactor volumes are used often only insufficiently or raw material leaves the biogas reactor without a sufficient reduction. On the one hand, the biogas yield is reduced by the insufficient anaerobic degradation of the raw material and on the other hand, methane emissions can have a negative effect on the environment of remaining material. Furthermore floating layers and sediment layers can be removed often only with a very big expenditure of work.

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.
