Regenerative Energie
The effects of crude glycerol on the performance of single-stage anaerobic reactors treating sewage sludge were examined. A significant decrease of biogas production in the digester fed with sewage sludge supplemented with 3% crude glycerol was observed after 20 days of operation.
On the other hand, primary sludge containing 1% crude glycerol showed the highest biogas production rate. The reactor treating the sewage sludge produced 1106±36 CH4/d before the addition of glycerol and 2353±94 mL CH4/d after the addition of glycerol. The supplementation of the feed with glycerol resulted in a higher organic loading rate, not only had negative effect but contrary enhanced more than the theoretical value the reactor performance.

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.
