Regenerative Energie
The ReMFra project encompasses two sustainable solutions for treating by-products derived from steel production. The first is a novel Plasma Reactor for the treatment of coarsegrained by-products.
The second is the RecoDust process for treating fine-grained by-products, including those derived from the basic oxygen furnace (BOF), electric arc furnace (EAF) and the HIsarna process, a smelting reduction technology for ironmaking with a reduced carbon footprint. The primary objective of the RecoDust process is the separation of zinc and iron from fine-grained feedstocks via smelting and reduction in the so-called Flash-Reactor. This paper describes two trials, in which a zinc separation degree of over 98% could be reached with a highly stable pneumatic dosing rate being one important requirement for an efficient process. The specific energy demand is significantly lower than before, thanks to previous optimisations. This also resulted in a significant high zinc separation, from approximately 20% in the feedstock to less than 0.3% in the iron-rich RecoDust slag (RDS), one of the two products from RecoDust (crude zinc oxide dust is the second product stream).

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.
