"PFAS are some of the worst environmental pollutants, and unfortunately we don’t yet have green methods that can completely break the very strong carbon-fluorine bonds that make the substances extremely resistant to natural decay," says Assistant Professor Zongsu Wei. Photo: Zongsu Wei.

Research project to eliminate ‘forever chemicals’

The Novo Nordisk Foundation has granted funding to a project to develop a multi-step system to treat water for per- and polyfluoroalkyl substances. The method is based on nature's own enzymes and a completely new nanomaterial being developed by researchers at Aarhus University.

New discovery opens novel pathway for high-titer production of drop-in biofuels

Using an unusual, light-dependent enzyme and a newly discovered enzymatic mechanism, researchers from Aarhus University and Massachusetts Institute of Technology have enabled the biological synthesis of high-yield industry relevant production of climate neutral drop-in fuels from biowaste.

Ammonia (NH3) is today primarily based on the so-called Haber-Bosch process, invented in the early 20th century. The process is one of the largest contributors to global CO2 emissions. Photo: Istock.

Researchers aim to make ammonia production 100% green

In a new project, researchers from Aarhus University and Stanford University will develop a sustainable technology for local-scale production of green ammonia.

Danish researchers develop budget optical ammonia sensor

In collaboration with the Technical University of Denmark (DTU), the Department of Engineering at Aarhus University has developed photonic sensor technology that can pave the way for a portable, reliable and, above all, inexpensive device for detecting ammonia and other gases in agriculture.

You need to know something about textile fibres and particle chemistry if you want to design an effective face mask. And it has to be sewn so that it perfectly fits your face. These are the conclusions from last week's face-mask speed experiment at Aarhus University (Photo: Colourbox)

Students test face masks in the laboratory

There are large differences in how well cloth face masks filter particles, and it is crucial that they fit snuggly against your face. These are the main conclusions of an experiment at Aarhus University.

How do you recycle composite from wind turbines?

When composite from wind turbines is to be disposed of then it either ends up in landfills, or it is incinerated. However, researchers are working on a sustainable way of recycling the composite material, says Mogens Hinge, expert in plastics from Aarhus University, in this blog post.

DKK 14 mill. for engineering research on the green transition

Independent Research Fund Denmark (DFF) has just published the 65 research projects on the green transition that have been awarded grants. Researchers from the Department of Engineering, Aarhus University will receive grants for five new engineering projects.

From Danish hemp fields to sustainable textiles

One hectare of Danish-grown hemp can replace 2-3 hectares of cotton and requires significantly less water in production. A new project, supported by Innovation Fund Denmark, aims to develop a method that will make the hemp textiles a sustainable alternative to cotton.

Intelligent camera technology to revolutionise plastics recycling

A new research project is aiming to develop a camera-based separation system that can separate plastic waste according to type. The machine will be implemented at plastic recyclers, enabling the manufacturing industry to significantly increase the use of recycled plastics.
