STW grant

Date of news: 27 November 2015

In November 2015, five interdisciplinary research programs were granted 24 million Euros by Technology Foundation STW to transform fundamental research into innovative technologies. The HFML is involved as a partner in one of these five programs, together with universities and companies throughout the Netherlands.

STW-EngInstead of producing high-tech materials over and over again from ore and oil, it should also be possible to recycle them from waste products. The program ‘Innovative Magnetic Density Separation for the optimal use of resources and energy’ aims to develop a recycling technology for waste products that consist of over one hundred different high-tech materials, like scrap electronics or plastic packaging.

Magnetic Density Separation

The idea is to implement Magnetic Density Separation (MDS) in this technology. MDS is a special method of float-sink-separation where particles of different materials compile at specific heights in a magnetic fluid, according to their density.

Andries den Ouden, ohead of superconducting magnet technology, is one of the collaborators. He explains: ‘At HFML, we will house a postdoc researcher for two years. Together, we will work on the design and realization of a superconducting magnet that can serve as a testbed for the research and development of this new technology.

‘For instance, we will investigate the flow of the ferromagnetic fluid, the interaction of the particles in the ferrofluid with the waste particles and the optimal size of the ferrofluid particles. The actual building of the magnet system will take place at the Universiteit Twente.’

In this project, Andries den Ouden and his colleagues work together with scientists from Technische Universiteit Delft, Technische Universiteit Eindhoven, Universiteit Twente and Universiteit Utrecht and with colleagues from Urban Mining Corp and Didde Magnetic Engineering. Professor P.C. Rem from Technische Universiteit Delft is the program leader.
