Regenerative Energie
Contrasting thermochemical technologies are used, leading to the production of differentend products such as gas, oil and solids. Pyrolysis (pyrochar) and hydrothermal carbonization (hydrochar) are prominent technologies converting organic residues or waste into charcoal or end products resembling charcoal. Due to the different production conditions of these technologies, end products have fundamentally different properties.
Pyrochars are inert, having a highly condensed aromaticring system, where as hydrochars are still rich in carboxyl and hydroxyl groups leading toa high reactivity. Despite or even because of the different material properties of hydrochars and pyrocharsfields of application are highly diverse. Pyrochars can be used for soil Amelioration and long-term carbon sequestration. In contrast, the addition of hydrochars to the fermentation process increases gas yield significantly. Furthermore, the hydrothermal carbonization process can be utilized to produce furfurals like 5-HMF. Hydrothermal carbonization, as well as pyrolysis, are both technologies with high potentials of using organic residues in a multiple sequential way, closing material cycles and refining biomass and waste.

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.
