Regenerative Energie
In municipal solid waste incineration plants (MSWI) there are varying waste compositions at the feeding system of the plant and changing energy output (district heating and steam). Consequently, different process conditions arise.
The optimization of these plants requires - according to the actual operating condition - detailed material, mass and energy balances, as well as further information about operational behaviour (e. g. corrosion). The newest MSWI plants are equipped with measuring process control systems delivering enough process data to allow online balancing for the different single units and, consequently, also for the overall process.
Such a detailed description of the actual state of MSWI-plants is not yet available. However, with such a tool of online balancing (also referred to as feed forward control) the operational staff will initially be able to optimize the overall process manually.
Objectives of this manual optimization are, for instance, the increase of overall energy efficiency, the saving of additional materials, longer operating period and, consequently, the improvement of economic operation and results.
In this paper the development of an online balance program, its connection to the process control system of the MSWI-plant Schwandorf in Bavaria/Germany, and the valuation of the obtained results are described. At first the fundamental basics of the balancing (method) are explained.
The illustration of the current operational state with the help of an online balance program in the waste incineration plants Schwandorf, Burgkirchen and Coburg is done in the project “EU 24 – Effectiveness of Waste Incineration Plants; Technical, Ecological and Economic Optimization.” This project, with the further project partners of the three plants in Schwandorf, Burgkirchen and Coburg, as well as the plant engineering/construction company in Munich (Martin GmbH für Energie- und Umwelttechnik München), is being supported by the State of Bavaria Department of Health, Environment and Consumer Protection as part of EU infrastructure funding for regional development (EFRE).

Rechtliche und praktische Unsicherheiten bei der Durchführung des europäischen Klimaanpassungsrechts durch das Bundes- Klimaanpassungsgesetz (KAnG)
© Lexxion Verlagsgesellschaft mbH (6/2025)
In the context of the European Climate Law (EU) 2021/1119), the Governance Regulation (EU) 2018/1999 and the Nature Restoration Regulation (EU) 2024/1991, the KAnG came into force on July 1, 2024.
Transformatives Klimarecht: Raum, Zeit, Gesellschaft

This article contends that climate law should be conceived as inherently transformative in a double sense. The law not only guides the necessary transformation of economy and society, but is itself undergoing transformation.
