Civil engineering constructions are primarily functional. The Climate Adaptation Lab aims to add functions to weirs, sluices and bridges by encouraging civil engineering and architecture students to work together.

With their latest genetically modified yeast, TU Delft researchers think they can boost bioethanol production from agricultural waste. “Within two years the first full-scale plants for second generation bioethanol will have started production.”

One of the largest laboratories for nanotechnology research in Europe lies right here in Delft; TNO’s and TU’s Van Leeuwenhoek Laboratory. It became fully operational last summer.

The climate is changing, the end of fossil fuel stocks is in sight and more and more people live in cities. All this creates the need for different uses of resources like water. Rutger de Graaf studied options for sustainable water management in urban areas.
