Dynamic MFA Modelling on Individual Building Level: Exploring Secondary Material Supply in the City of Hamburg

This research delves into the challenging task of exploring secondary materials supply from existing building stocks, crucial for sustainable resource management in the face of climate change. Focused on Hamburg, Germany, the study employs a unique combination of GIS-based bottom-up building stock analysis and dynamic Material Flow Analysis ...

Navigating New Horizons: Mapping the Global Technical Potential and Exploring the Material Demand of Offshore Floating Urban Dwellings: A GIS-based Approach Integrating Technical and Motivational Perspectives to Provide Insights into the Global Technical Potential and Associated Material Demand of Modular Floating Structures and Circular Floating Breakwaters as a Proposed Alternative for Sustainable Coastal Communities

Modular Floating Structures (MFS) have emerged as an innovative alternative for sustainable offshore urban development, providing a response to the multifaceted challenges posed by coastal urban expansion: significant urban growth and coastal migration, increasing sea-level rise exposure and land scarcity. This thesis presents a geographically...

Material stock of buildings in Brno: Towards circularity in the construction and demolition industry

GIS bottom-up analysis of the material stock of construction materials (concrete, bricks, mortar) in buildings in Brno, Czech Republic.

The Missing Stock: Exploring Concrete Use in Trondheim’s Residential Building Foundations

Concrete is one of the most widely used materials in residential building construction. It contributes about 4% to 7% of global greenhouse gas emissions annually. Thus, better understanding the material stocks and flows of concrete can support efforts to better manage this resource and its use. Concrete is especially popular for the construction...

Analysing the Waste Potential of Solar PV In India

With growing demand for energy and the shift towards renewable energy, countries like India are targeting energy mixture with alternate sources like solar, wind and water. With the current growth of solar energy use in India, it is predicted that high amounts of Solar Photovoltaic (PV) waste would be generated in the near future which left...

Integrating Reuse in MaTrace Models: An implementation and evaluation

The growing world population gaining affluence is driving the extraction of raw materials. Resource availability is finite and concerns about future supply shortages rise. An approach to tackle this problem is circular economy which entails multiple strategies to reduce the demand of virgin materials. The implementation of those strategies...

The silicon carbide industry in the spotlight – Energy Intensive Industries (EIIs) and the sustainability transition

Transitioning of energy intensive industries (EIIs) towards more sustainability forms an important building block in achieving the Paris climate goals. Silicon carbide (SiC) production is such an EII, though it has not yet received much attention in systemic research. This thesis attempts to fill this gap by studying how SiC flows through the...
