Regenerative Energie
In low carbon waste landfills the availability of water or a carbon source, or the build up of toxic compounds appears to limit anaerobic gas generation. Thus oxygen consuming chemical/biological reactions occur immediately after the waste is placed, but factors required for anaerobic degradation become exhausted, perhaps because of limited permeability that also appears to be a feature of this waste. Oxygen and its reaction products, principally carbon dioxide, are removed by phase change from the gas filled pore space of the waste.
This results in the proportion of nitrogen in the pore gas rising to more than the 80% typical of atmospheric composition. Nitrogen gas enrichment through oxygen removal can mean either negative pressure within the landfill, or slow air ingress into the waste. New gas management and monitoring techniques at such sites should reflect this different conceptual model.
In landfills containing non-inert waste with low-carbon content, chemical reactions may be more important than biological processes for gas generation. This means that for the risk assessment of a landfill containing a low-carbon waste the source term is different from a typical MSW landfill and so current models are not appropriate for these facilities. There appear to have been no systematic studies of the nature and composition of gas accumulating within wastes having a low content of biodegradable carbon. This study aimed to collect representative data that might inform the rational design of gas management infrastructure and monitoring requirements at sites containing low-carbon, non-inert wastes.

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.
