Tin is an important metal for society with a high risk of supply disruptions. It is, therefore, classified as a critical material in many parts of the world. An exception is the European Union, for which tin was classified as a non-critical material in 2023. However, there are ...
Towards neodymium recycling
Analysis of the availability and recyclability of European waste flows
The world is facing a growing neodymium demand, creating the need for developing a recycling system to handle future waste flows. Recycling technologies are emerging, but the recycling system around them can only be established with knowledge about available end-of-life (EoL) pro

Data implementation matters
Effect of software choice and LCI database evolution on a comparative LCA study of permanent magnets
Life cycle assessment (LCA) databases and software evolve. We analyzed to which extent software and evolving life cycle inventory databases affect the comparison of technology alternatives, using a comparative LCA on permanent magnets as a case study, with two selected softwar ...

Tailings are a waste product of primary metal production. Although these metals contribute to the development of modern technology and renewable energy systems, tailings pose significant environmental, economic, and human health risks. Stored behind a dam in tailings storage faci

Digitalisation pressures the earth's resources, especially critical raw materials (CRMs). The CRMs, are functional materials that meet current challenges and future demands in information and communication technology (ICT). The extraction and processing of CRMs are highly concent

A circular hub for end-of-life wind turbine blades
Analysis of the location and magnitude of return volumes of wind turbine blades in and around the Netherlands until 2050 for the development of a circular wind hub at a Dutch port under the application of different circular strategies
Wind turbine blades are composed of complex composite material structures that are difficult to recycle at the end of their operational lifetime. As such, they are oftentimes landfilled or incinerated. Following the Circular Economy principles, there are a multitude of strategies

This thesis aims to develop an energy transition scenario for the cement industry using a simulation model that models energy flows to achieve net-zero emissions by 2050. The model's decarbonisation pathways are constructed with assumptions about the country's socio-economic cond

Air-to-Methanol via the micro-plant approach
An ex-ante Life Cycle Assessment
The capture of carbon dioxide before or after it is emitted has been regarded as a crucial mitigation pathway to prevent the rapidly increasing accumulation of CO2 in the atmosphere. The valorisation of the captured CO2 into value added products such as methanol provides an addit

Circular Economy Strategies’ Impact on Critical Raw Materials in Servers
A Case Study from the Perspective of a Dutch Telecommunications Company
Critical Raw Materials (CRMs), materials with high economic importance and supply risk, are the key components of strategic sectors, including Information and Communications Technology (ICT). With foreseeable growth in CRMs demand, principles such as Circular Economy (CE) strateg
