Civil Engineering and Geosciences
In ten years’ time the methods used to recycle plastic and electronic waste will be completely transformed, predicts Peter Rem, professor of Resources & Recycling at TU Delft. The recycling plants of today, with their huge sorting areas and big separation installations, will have been replaced by distribution centres for recovered raw materials which can be made into high-quality products.
Drilling for heat deep down below
The deeper you go into the ground, the hotter it gets. Richard Bakker, a researcher at the Geoscience & Engineering department, knows all about this. He has previously conducted research on volcanoes, but is currently working on geothermal energy. In other words, using the heat from the subsurface to generate sustainable energy.
SoSEAL: Securing leaking dykes using a natural binding agent
Even the most robust of dykes can be prone to seepage: groundwater that permeates the soil underneath the dyke and ends up in the polders behind them. It’s a headache for livestock farmers and water boards alike. Professor of environmental geotechnics Timo Heimovaara, postdoc Susanne Laumann and PhD candidate Jiani Zhou are currently testing SoSEAL, a technique inspired by a natural process which uses organic materials to seal permeable soil layers.
A better understanding of the Zambesi river
The Zambezi river basin is shared by eight African countries and is vital to the energy supply of Zambia. Hydro dams in the Zambezi river are generating energy but the river can also bring destruction to villages and towns through flooding. That makes mapping the river’s discharge patterns a matter of crucial importance. Hubert Savenije’s aim is to gain a better understanding of the river. What singles him out from most of his colleagues is that he approaches his subject from a slightly different angle.
How do people get to know a city?
What if you are a student or a tourist and you find yourself in a city you have not been to before? How do you go about finding your way? Do landmarks such bridges, churches and other characteristic buildings help? To find out, Transport & Planning PhD Lara Zomer kitted out 250 bikes with gps trackers.
The Dutch vulcanoes
An active volcano? In the Netherlands? Volcanologist Elske de Zeeuw-van Dalfsen has been asked this question on more than one occasion. ‘Actually we have not one, but two active volcanoes,’ she says. However, they are not situated in the flat and obviously volcano-less little country by the North Sea but in the Caribbean.
