Regenerative Energie
The building of biogas plants comes along with a considerable economic risk, in particular when unknown organic substrates are involved. To minimize this risk it is highly desirable to mimic the industrial scale processes first in the laboratory. This provides a cheap and simple way of investigating important process parameters like biogas potential, methane yield, microbial inhibition, etc. The results of these investigations are useful both in the planning and productive phase of the plant. In this paper we present the results of an investigation of feasibility, comparability and reproducibility of this approach. (Session A11: Biological treatment -anaerobic digestion (II))
The aim of the investigation of this paper was to prove the reproducibility of anaerobic processes. To examine this approach digesters have been run in the laboratory over an 11 weeks period with input taken from a co-fermentation plant. The laboratory conditions were adjusted to the biogas plant with respect to temperature, hydraulic residence time, input substrate, feeding schedule and mixing. To examine the reproducibility of the results inside the laboratory scale, the experiments were run parallel in two laboratory digesters. By means of the process describing parameters - degree of degradation of VS and TOC, biogas yield, NH4-N, sum of organic acids - we examined the processing at the laboratory scale and the application to the industrial scale.

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.
