Regenerative Energie
During the processing of solid waste for the recovery of valuable materials certain residual fractions are inevitably created. As a rule, these cannot be processed at state-of-the-art solid waste processing technology for economic reasons and for quality restraints.
Thus, any contained valuable materials are largely lost for the economic cycle or removed for the long-term by incinerationor landfilling. The more complex mixtures of solid waste from anthropogenic utilization grow, the greater the proportion of residue fractions after processing. In particular, fine-grained material send up in such residual fractions.Through individual examination of objects it is possible to record detailed geometric data thatcannot be detected in mechanical methods or processes. Such data can be used to determine grain sizes according to varying definitions and to deduct information concerning grain shape. Inliterature, a variety of shape indices is proposed. In this study, filling level, surface ripple factor,aspect ratio, sphericity and symmetric elongation were used. So-called descriptors serve for the calculation of these indices. Descriptors are simple geometric properties of an object. These are usually measures of length, as well as areas or volume.

Rechtliche und praktische Unsicherheiten bei der Durchführung des europäischen Klimaanpassungsrechts durch das Bundes- Klimaanpassungsgesetz (KAnG)

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.
