MBT-Landfill as Carbon Sink - Expected Carbon Content after Aeration

Target of MBT (mechanical biological treatment of wastes) is to mineralise and to stabilise waste organic matter. This leads to a reduction of emissions after landfi lling the pretreated wastes. It is well known, that MBT-landfills can be seen as a carbon sink, but there is a deficit in knowledge about the time frame respectively which share of organic carbon will remain in the landfill over long period.

During last decades at ABF-BOKU approximately 800 incubation tests (according to Ö-NORMS2027 part 2 2012) were analysed (380 MBT samples and 330 samples from old landfill sites). Many of these tests were carried out over much longer test periods than minimum duration (21days + lag-phase) described in the Austrian standard. Duration was several 100 days up to 8 years! 141 of these long-term tests were evaluated to get an idea about gas formation potential respectively the 'end-carbon-content†in MBT-landfills. In a first step a prediction model (log-normal distribution curve) for gas formation potential was developed (Tintner et al. 2011; Binner et al. 2013). Actual the gas formation potential of 91 MBT-samples and 27 samples from old landfills was estimated by this model. The MBT-samples were taken in 12 Austrian MBT plants. Thus feedstock materials and mechanical treatment as well as duration of treatment of the analysed samples differ very huge.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens - ein Rechtsvergleich
© Lexxion Verlagsgesellschaft mbH (8/2024)
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.
