Civil Engineering and Geosciences
The oceans of the world are filling up with plastic waste carried there by rivers. Where it all comes from no one knows. Wim Uijttewaal, professor of Experimental Hydraulics and professor of Resources & Recycling Peter Rem are on a mission to make the rivers plastic free. ‘We want to turn the removal of plastic from rivers into big business. And we want to devise a plastic waste radar that will show where the plastic is, and how it got there.’
The geocentrifuge: a time machine for soil
What happens underground when a landslide occurs? And how do we prevent a high water load or the weight of passing traffic from causing a dike to collapse? Assistant Professor Amin Askarinejad explains how the geocentrifuge at TU Delft can provide detailed simulations of long term subsurface processes in a short time.
Mapping minerals with sensor technology
Minerals are of great importance to our modern society. From smartphone to laptop, these elements are everywhere. First they need to be extracted from the earth however, an often environmentally taxing, slow and complex process. But this will change soon, if it’s up to PhD student Feven Desta. Desta researches sensor technologies to look for minerals in an environmentally friendly way.
Electricity from biogas
For people living in the rural areas of developing countries access to electricity is often non-existent or limited at best. Ralph Lindeboom is heading a team that is working on a biogas fuel cell system which generates electricity from organic waste (water). ‘In some ways Ugandan farmers and astronauts are very similar.’
Virus removal by low-cost ceramic membranes
Ten years after Doris van Halem’s graduation, the ceramic pot filter has become a major hygiene intervention tool. The system is of a brilliant simplicity: a ceramic pot with tiny holes filters larger micro-organisms, such as bacteria, from the water. The pots are now manufactured in factories around the world, using local materials. The only drawback is that viruses, which account for various water-borne diseases, such as hepatitis, are not removed. But fortunately Van Halem discovered something else as well all those years ago.
Climate adaptation starts (roof) top down
TU Delft is going to become a little bit greener on top: the roof of one of the lecture rooms of the faculty of Civil Engineering and Geosciences has been turned into a sustainable ‘polder roof’. The green blue roof can collect, store and discharge rainwater in a controlled manner. For researcher Olivier Hoes (Watermanagement) the roof is a field lab to research how this smart roof deals with heavy rains and heat stress.
Cycling for science at Ahoy
PhD students Alexandra Gavriilidou and Marie-Jette Wierbos have just finished an intensive cycling experiment. The checklist: 1000 metres of tape, 200 caps, 8 tracking cameras and 1 hall in Ahoy Rotterdam. Scientists have long shied away from predicting cycling behaviour but now TU Delft is gearing up to change all that.
