Optimal energy supply structures for industrial food processing sites in different countries considering energy transitions
(2017-05-10)
This study focuses on analysing the most energy efficient utility system supply structure in terms of carbon emissions, primary energy efficiency and energy costs. In the German food processing industry, the state-of-the-art technologies in the utility supply structure are a gas fired steam boiler for steam generation and ammonia chillers for chilled water generation. Low investment costs and its durability are attractive for industrial production sites. But, given the ongoing energy transition to renewable energy, ...

Managing Risk, Performance and Sustainability in Textile & Apparel Supply Chains.
(2023)
The thesis at hand analyzes sustainability prerequisites, practices, risk and performance in textile and apparel (T&A) supply chains (SCs). Given the growing awareness of sustainability risks by various stakeholders, T&A firms are required to implement and adapt sustainability practices along their SCs, while at the same time measuring their performance to counteract the (re)emergence of risks. Appropriate management strategies are therefore needed to ensure sustainable transformation in T&A SCs. While the state of ...

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.

The politics of energy landscapes: the influence of local anti-wind initiatives on state policies in Saxony, Germany
(2020-01-23)
Background
In recent years, landscapes in many countries have been transformed by efforts to fight global warming, specifically the shift towards renewable energies such as wind power. This development has been met by growing opposition from local citizens and their initiatives. There is an ongoing debate about whether and how such protests have a real impact on the development of energy landscapes.
Methods
Drawing on the rare case of a state government scaling back ambitious targets for the expansion of renewables, ...

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 ...

Working paper
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 ...

Colombia and the Coalition of the Pacto Histórico: From Extractivism to a Productive Economy?
(2022-07)
• The new Colombian president Gustavo Petro pushes for a transition from an extractivist to a productive economy.
• He needs to address the country’s enormous inequalities to achieve long-term peace.
• Agrarian reform and tax reform are urgent and part of the government’s plan.
• Mining will continue to be a strategic economic sector and a potential source of social conflicts that can weaken the action of
the new government if a dialogue with the affected groups is not established.
• With the new commodity boom ...
