Addition of an Anaerobic Treatment Stage to MBT Plants - Based on the Example of Rostock

In Germany, a large number of MBT and waste incineration plants are available for the pre-treatment of municipal waste.MBT plants usually separate waste into combustible fractions, mainly plastics, which can be thermally used in specific plants, and another fraction, which mainly consists of natural organic components and is treated aerobically in most cases.

In principle, mechanical(-biological) treatment processes have proven their functionality. Technical difficulties which arose during operation of such plants have meanwhile been solved to a considerable extent. However, there remains a need for optimisation in some plants and regarding certain parts of the MBT-technology.

In January 2004, the city parliament of Rostock decided on a major change in the concept: the MBT plant was still to be built, but plans for an incineration facility under the responsibility of the EVG were cancelled. The Vattenfall Europe New Energy GmbH is currently building an RDF-fired thermal power station next to the MBT plant. The foundation stone for the MBT Rostock was laid on 27 May 2004; operations commenced on 1 June 2005. A fermentation facility as an addition to the MBT plant was commissioned in July 2008.

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.
