Regenerative Energie
Elevated temperatures in landfills are caused by the biodegradation of the organic constituents of the waste or by exothermic chemical reactions within certain waste types. Concurrently with biodegradation, landfill gas is generated and leachates are created. The correlation of these indicators of biodegradation is complex and will change with the factors controlling the biodegradation process but, where the rates of biodegradation or chemical reactions change, it is to be expected that waste temperatures and landfill emissions will be commensurately affected.
This paper presents results of more than 6 years of temperature monitoring at the liner of a mainly MSW landfill in south-east England, with leachate recirculation during and after waste disposal. The paper also reviews published temperature data at other landfills and discusses the two main factors controlling the durability of HDPE geomembrane liners, being the lifetime temperature profile and the activation energy of the antioxidant depletion mechanism. The phases of degradation of HDPE liners are considered with the inclusion of the "half-life" of oxidative degradation within estimates of liner service life being questioned.

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.
