Regenerative Energie
The aerobic degradability of different types of biologically degradable polymer (BDP) packaging in two selected home composting systems was investigated during a test period of 12 months.
Tested items were starch based films, copolyester coated starch trays and poly lactic acid (PLA) cups. The results of two experimental test series are presented here: indoor pilot-scale experiments under optimised environmental conditions and outdoor pilot-scale trials under the conditions of European climate. Tested BDP items degraded well with the exception of (PLA) products. Mass based degradation rates of starch based materials were detected between 67 and 97% in indoor trials after 12 months of processing. The type of composting system showed only slight variations in the degradation velocity and final degradation values were detected in the same range. Generally no significant differences of the degradation behaviour between in- and outdoor composting trials and the different systems were detected.

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.
