CO₂ as Carbon Source
(2022-04)
This thesis examines several aspects of the use of CO₂ as a carbon source for the chemical industry in Germany. The analysis focuses on the usage potential for CO₂ in the chemical and plastics industries, the current and future competitiveness for the production of CO₂ based chemicals in Germany and the characteristics of a CO₂ based value chain for polymer products. To investigate the different aspects, multiple methods of system analysis are applied, which investigate environmental and economic aspects of CO₂-based ...

Unsicherheitsfaktor globale Landbedeckung: Konsequenzen für die Landsystemmodellierung
(2022-01)
Änderungen im Landsystem sind eine zentrale anthropogene Ursache globaler Klima- und Umweltveränderungen. Der stetig wachsende Bedarf an landwirtschaftlichen Flächen für Nahrung, Futter, Fasern und Energie und die damit verbundene Konversion natürlicher Ökosysteme gelten als wesentliche Triebkräfte der Landänderungen. Globale räumlich-explizite Landsystemmodelle tragen dazu bei, ein besseres wissenschaftliches Verständnis für derartige Landänderungsprozesse zu erlangen und zukünftige Entwicklungen mit Szenarien zu ...

Sustainable alternative water supply systems
(2023)
Freshwater is a critical resource which is intrinsically limited (only about 0.8% of Earth’s water is accessible freshwater) and chronically scarce. Therefore, given the rapidly dwindling supply and unceasing demand that multiplicatively exacerbates global freshwater scarcity, achieving water supply security has become a principal requirement and an endeavour for humankind. Water scarcity is considered a long-term threat to life on Earth; thus, alternatives are sought within the inherently limited options. To that ...
