Scientists at the University of Bath have developed a new method for tackling ‘forever chemicals’ in wastewater and removing these contaminants from the environment.

Removing perfluoroalkyl and polyfluoroalkyl substances (PFAS) from water has become an increasingly important environmental challenge as the impact of them on both human and environmental health has become better understood.

These harmful contaminants are commonly referred to as 'forever chemicals,’ because once they’re in the environment or our bodies, they can take up to 1,000 years to break down. They have been used for decades in a variety of applications and persist in the environment and human body due to very strong molecular bonds that bind them together, leading to health issues linked to cancer.

The innovative solution from the University of Bath involves 3D-printed ceramic pieces infused with indium oxide, which are designed to bond with PFAS molecules and capture them when submerged in polluted water. In initial testing, these 3D-printed ceramic pieces – which look like frozen waffles or a clump of dried instant noodles, were able to remove 53 per cent of PFAS from polluted water within three hours.
