Entwicklung einer vereinfachten europaweit anwendbaren Methodik zur Festlegung von Effizienzanforderungen an Wärmerückgewinnungssysteme in der Raumlufttechnik für Nicht-Wohngebäude auf der Grundlage mehrdimensionaler Optimierungsberechnungen
(2022)
Die vorliegende Dissertation beschäftigt sich mit der Anpassung der EU-Verordnung 1253/2014, welche die Effizienzkriterien an die WRG von RLT-Geräten in NWG festlegt. Die Verordnung definiert die Anforderungen als starre Grenzwerte, die vom Süden bis zum Norden Europas gelten ohne den jeweiligen Standort oder die Gebäudenutzung zu berücksichtigen. Gemäß den Referenzwerten der aktuellen Verordnung wurde eine Verschärfung des Anforderungsniveaus diskutiert, wobei auch hier zunächst starre Grenzwerte geplant waren. Der ...

Gold Mining (artisanal gold mining): Is it an engine of development in Mauritania?
(2023)
• In 2021, Mauritania exported approximately 13 million tons of iron, 20% of which was bound for Western Europe.
• The economic structure of this country is increasingly rent based.
• The extractive sector does not act as a catalyst for the country's development. Its contribution to poverty reduc-tion remains insignificant.
• Poverty remains a significant feature of the country, ranking 157th out of 189 according to the Human Development Index in 2020.

Argentina in the context of the global socioenvironmental crisis
(2023-07-26)
• Agro-extractivism has shaped the productive matrix during the last four decades in Argentina.
• Agro-extractivism not only does not satisfy the population's food demand, but also deepens the socio-environmental crisis, generating environmental depredation, health problems, economic concentration, and social polarization.
• To overcome the crisis of agro-extractivism in Argentina, it is necessary to transform the patterns of production, consumption and accumulation, which will require democratizing access to land ...

Lignocellulosic biorefinery with a thermo-biological pretreatment concept
(2023)
There is great interest, not only in technologically advanced societies, in developing innovative sources of raw materials, especially lignocellulosic biomasses such as cereal straw, which do not interfere with food production. In Germany, 4 – 9 million tons of cereal straw, mainly wheat, are utilized annually, corresponding to an energy potential of 57 – 129 PJ/a. Lignocellulose, found in plant cell walls, consists of hemicellulose, cellulose, and lignin, and it requires complex fractionation to enable its polymers ...

Assessing African Energy Transitions: Renewable Energy Policies, Energy Justice, and SDG 7
(2021-02-26)
Renewable energy has made significant inroads in addressing growing energy demands on the African continent. However, progress towards SDG 7 is still limited and difficult to trace. Furthermore, the results-oriented rationale of the SDGs means that both policy change and the dimension of environmental justice are not covered properly. We argue that the energy justice concept may provide a powerful tool to offset looming trade-offs and enhance the co-benefits of SDG 7 within broader transition endeavours. In doing so, ...
