He will investigate the fate of PFAS through incineration

For the fourth year in a row, EasyMining is providing an opportunity for a summer trainee to join our team. This year, we welcome Oliver Danielsson, a biology student from Stockholm University. Oliver's project is closely linked to our Ash2Phos technology and involves investigating PFAS substances in ash from sewage sludge incineration and their impact on the environment.

The eight-week summer trainee program, organised by Ragn-Sells, including EasyMining, offers a unique opportunity for hands-on experience. As a trainee, you will have the chance to work across various Ragn-Sells operations, establish connections with senior executives, and even lead your own project within the company.

This year, EasyMining welcomes Oliver Danielsson, a master's student in biology from Stockholm University, to join the team.

– I look forward to the opportunity to work within the environment sector and securing references for future employment. Ragn-Sells is actually one of very few companies that introduces newly educated or still studying students to the job market in a meaningful way, Oliver says.

Oliver will be working under the guidance of Sara Stiernström, Product Manager at EasyMining.

– It feels great to have Oliver on board. Investigating the fate of PFAS in incineration of sewage sludge is an important step in closing nutrients cycles in a safe way, says Sara Stiernström.

Preventing the recirculation of PFAS in society

EasyMining's Ash2Phos process is designed to process ash from incinerated sewage sludge and extract valuable elements such as phosphorus.

PFAS (per- and polyfluoroalkyl substances) are persistent chemicals that accumulate in the environment and are often found in wastewater with limited degradation. Among various treatment methods, incineration offers the only possibility to destroy PFAS.

However, there is limited knowledge regarding the fate of PFAS during incineration, particularly the comparison of PFAS levels between sewage sludge and sewage sludge ash. This information is crucial for the Ash2Phos process to prevent the recirculation of PFAS back into society.

- During my internship, I will be looking into how the burning of sewage sludge affect the PFAS levels in the remaining ashes. Hopefully, the project will help us understand the fate of PFAS and possibly point to gaps that need more attention.
