Implementing a circular economy in cities has been proposed by policy makers as a potential solution for achieving sustainability in the construction sector. One strategy that has gained interest by both policy makers and companies is to develop “circular construction hubs”: locations that collect, store, and redistribute waste as secondary...

Hogenkamp, Laura (author)
The building industry is one of the most resource-demanding and polluting industries in the world. Therefore there is a need to apply the circular economy principles within the industry enabling the transition towards a circular built environment. This transition requires the reuse of building components. However current practice shows that only...

Re-use and recycling in the construction sector is essential to keep resource use in check. Data availability about the material contents of buildings is significant challenge for planning future re-use potentials. Compiling material intensity (MI) data is time and resource intensive. Often studies end up with only a handful of datapoints. In...

The Dutch government aims to become fully circular in 2050 and to reduce the virgin material demand by 50% in 2030 (Rijksoverheid, 2016). For a country that has relied on a linear economy for centuries, this will prove to be a major challenge (Circle Economy, 2020; Rijksoverheid, 2016). Simultaneously, due to urbanization, the Dutch government...

Hui, W.H. (author)
The project site in Anderlecht, Belgium exists a fragmented urban fabric in terms of morphological evolution in the post-industrial period, functional mix of the urban plot, connection with the immediate urban grains and the ephemeral state of ownership of spaces around the site. However, the nomadic site actors practise informal ‘urban mining’...

SummaryThe municipality of The Hague and the Social housing associations are researching on how to cope with the population growth in The Hague. Every year approximately 5,000 new persons arrive at The Hague, meaning that in 10 years The Hague will increase their population by 8%. The main problem is that currently, the city has a shortage of...

Dronkers, Maaike (author)
The combination of the building sector as one of the largest consumers of natural resources with the changing needs and standards of the Dutch population aks for a transition in building methods. This thesis showcases the potential of reusing local resources in architectural design. On the one hand, the Harvest Hub facilitates the logistic...

van der Zaag, Jochem (author)
To allow society to operate within planetary boundaries, it is essential to reduce primary material consumption. The Dutch government has set goals to limit the primary extraction by half in 2030 and to be a fully circular economy by 2050. To be able to achieve this without reducing our standards of living, the only way is to extract the...

Urban mining aims at reusing building materials enclosed in our cities. Therefore, it requires accurate information on the availability of these materials for each separate building. While recent publications have demonstrated that such information can be obtained using machine learning and data fusion techniques applied to hyperspectral...

Franssen, Niels (author)
In most of the current starting construction projects, most stakeholders use virgin materials for building elements. Considering climate change, building materials are getting scarce, it is necessary to reduce the number of virgin building materials and improve circularity in the construction industry. The problem is the absence of a middle man...

Recently, the application of machine learning and data fusion techniques on hyperspectral imagery have demonstrated potential for ground cover classification at material level. Hereby, specific locations of resources enclosed in cities (e.g. roof materials) can be identified, which is critically relevant within the field of urban mining. A...

Lukkes, Dominik (author)
Our excessive need for new building materials is causing our natural material stock to be depleted at an alarming rate. What happens if our most common building materials can no longer be acquired? This thesis shows the potential in reusing buildings and the components they comprise of by setting an example. An existing office building is...

Cobalt is one of the most important critical raw materials for emerging technologies. There are many incentives for analysis of this metal, from increasing demand for rechargeable batteries, rising prices and social issues involved. This paper is the first attempt to perform a substance flow analysis of cobalt at a city level. The analysis...

Gremmen, Luuk (author)
Circular building has been increasing in popularity over several years. The idea being that we should not use resources only once and then discard them, but continue using them in new products. The construction industry has responded to this by designing 'circular' buildings that can be disassembled at the end of their functional life. This...

de Haes, Sabine (author)
Large material flows are extracted from natural mines in the earth’s crust and moved and stored in anthropogenic environments. Extraction processes from natural mines are often harmful for the environment and can cause material scarcity. At the same time governments are formulating ambitions to increase circularity in cities. For these reasons...

In recent years there has been growing interest in urban mining in buildings from various environmental and economic perspectives. Materials hidden in buildings are attractive alternatives to raw ones and building activities are responsible for a large share of urban waste in many societies. The paper presents an analysis of possibilities for...

Bon, Matthijs (author)
One way to stimulate a more circular economy, is to explore opportunities for urban mining. This thesis explores a new method to assess the quantity of underground electricity cables which could one day become available for urban mining. This research answers the question: ”To what extent can topological networks be used to localize and quantify...

According to estimates of the German Federal Ministry for the Environment, the German building stock contains around 10.5 billion tonnes of mineral building materials, around 220 million tonnes of timber products and around 100 million tonnes of metals. Due to continuous building activities, especially renovation and retrofit measures, it is...

Since a few years, the construction sector is focusing on minimizing resources exploitation and waste arising on construction sites. The European Commission has highlighted prevention and reuse as key actions for waste management. The Brussels Capital-Region is a densely built region, generating more than 600 000 tons of C&D waste each year....

NdFeB permanent magnets have different life cycles, depending on the applications: from as short as 2–3 years in consumer electronics to 20–30 years in wind turbines. The size of the magnets ranges from less than 1 g in small consumer electronics to about 1 kg in electric vehicles (EVs) and hybrid and electric vehicles (HEVs), and can be as...
