Researchers can track hazardous chemicals from fast-food wrappers in the body

Scientists have developed a new method that enables researchers to radiolabel three forms of perfluorinated and polyfluorinated alkyl substances and track the fate of these chemicals when they enter the body.

Energy from toilet wastewater

Wastewater is considered to be of no use - quite wrongly! Washing water has an average temperature of 30 C. Toilet water might not only be used to produce biogas or fertilizers, but also valuable resources that otherwise would enter the sewer system unused.

Vitrimers: the rise of recyclable plastics

With renewed fundamental insights on the chemical process of the reprocessing, researchers succeeded in controlling the properties and reprocessing of vitrimers by addition of specific additives, both for rubbers and hard plastics.
