Regenerative Energie
Different directives of the European Union may require operators of Waste to Energy WTE plants to monitor the composition of their waste feed with respect to the Content of biomass and fossil organic matter. The mass fractions of both materials are not only of relevance for the amount of fossil and thus climate relevant CO2 emissions of the plant, but also for the ratio of renewable energy generated, as biomass in wastes is considered as renewable energy source.
In recent years different methods, including manual sorting, selective dissolution, the radiocarbon method and the Balance Method have been developed to determine the biomass content of waste, and thus the fraction of renewable energy and fossil CO2 emissions produced by WTE plants. Until now all of these methods have been applied to different WTE plants and different wastes aiming at, on the one hand, the determination of characteristic values for the biomass content and fossil CO2 emissions and on the other hand, at a comparison of the different analysis methods. With respect to the latter, results of the different studies indicate that methods requiring waste feed sampling - e.g. sorting analysis or selective dissolution method - are much more vulnerable to waste heterogeneity and temporal changes in waste composition as quantities of manageable waste samples (at Maximum a few tons) are very small in comparison to the total amount thermally utilized.

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.
