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.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
