In his doctoral thesis, Mr. Jokari Sheshdeh deals with the simulation and analysis of energy systems based on renewable energies.
Research topic
Feasibility study on the transition to an energy system based on renewable energies in oil-producing countries; case study on Middle Eastern countries
This study attempts to use the experience gained from the energy transition to develop sustainable energy systems based on renewable energies for oil-producing countries. The aforementioned transition in these countries would face several challenges due to the current energy systems. These challenges are listed and analyzed in the study. In addition, several energy systems will be designed, simulated, optimized and analyzed in the selected regions in order to gain a better understanding of the implementation of such systems in these countries.

Research topic
Material limits of the circular economy – status and perspectives of the circular economy under characterization, modelling and evaluation of the material balance with special appreciation of stock dynamics in Germany’s anthropogenic stockpile
The circular economy is increasingly seen in political programs as a consistent solution for a sustainable, resource-conserving economy. The central paradigm of the circular economy is the preservation of the value and function of goods, products and materials in the economic area. As a result, an ideal raw material-utilizing system in a steady state would have to be largely self-sufficient in secondary raw materials and be able to dispense almost entirely with primary raw materials.
However, real systems such as national economies are characterized by a complex, dynamic material interdependence with losses and veritable consumption of raw materials. Recycling is subject to technological and economic barriers. Furthermore, these systems not only experience saturation effects, but also considerable growth and shrinkage dynamics in the anthropogenic camp. There is a large time lag between the placing on the market and the disposal of relevant groups of goods.
Against this backdrop, where are realistic material target corridors in a circular economy and where are the limits? Which materials can actually be managed in cycles and which indicators can be used to reliably describe the development of material life cycles? To what extent will the supply of primary raw materials remain necessary?
The author’s doctoral project is dedicated to these central questions and examines the degree of circularity that will be possible for various materials under current and expected future technical conditions.

Vita
Pauline Jegen, born in Aachen in 1996, has been a scholarship holder at the INZIN Institute since October 2021. She previously studied industrial engineering with a specialization in civil engineering at RWTH Aachen University. She focused on the specializations of water management and sustainability and cooperation. During her studies, she gained practical experience in construction management and project management, as well as in an engineering office for wastewater management and technical services.
Research topic
The construction industry is one of the most resource-intensive sectors of the economy and is responsible for a large proportion of global greenhouse gas emissions. The construction industry is also one of the biggest sources of waste, particularly through the demolition of buildings and roads. Mineral construction and demolition waste accounts for more than half of the total waste stream generated in Germany. The rubble and demolition waste produced can be reused as recycled building materials. However, the largest proportion is used in downcycling processes. Due to population growth and urbanization, construction activities will continue to increase worldwide in the coming years, which will also increase the demand for raw materials. The question therefore arises as to how more effective management of mineral construction and demolition waste can be implemented.

Taner Akbay, born on 01.06.1987 in Hanover, has been working as a specialist engineer for EEW Energy from Waste GmbH since the end of 2017. He previously studied mechanical engineering at Leibniz University in Hanover. As a specialist engineer for flue gas cleaning, he supports and optimizes the company’s waste incineration plants with the aim of safely complying with the emission limits in accordance with the 17th BImSchV. In addition to applying engineering knowledge, he uses the latest AI technologies such as neural networks or machine learning to predict, for example, fluctuating pollutant concentrations, contamination in the steam generator or difficult-to-measure temperatures in the combustion chamber due to the inhomogeneity of the waste. This is because the availability and optimum operation of the system can be increased by recognizing the interdependencies at an early stage.
