Research projects on Waste Science and Technology

Arsenic (As) and polycyclic aromatic hydrocarbons (PAH) were used in Sweden for decades in wood preservatives, leading to severe soil and groundwater contamination. Remediation of such areas is complex and costly, often conflicting with principles of sustainable resource use, while effective in sit...

Our project aims to revolutionize the approach to addressing PFAS remediation in soil by raising awareness of precursor management while developing innovative techniques.

The BEAR project aims to boost biogas production in Arctic regions through smart process optimization, new substrates, and improved microbiology. The goal is to increase energy efficiency, reduce emissions, and contribute to a more sustainable and profitable biogas sector in northern Scandinavia.

A new PhD-student project has been granted by the Wallenberg Initiative Material Science for Sustainability (WISE).

The aim of the project is to develop a treatment technology that can be flexibly applied to remove and destroy a wide range of PFAS compounds from contaminated soil and water, thereby contributing to the reduction of persistent chemicals in the aquatic environment.

The purpose of this project is to identify sources of error in the sampling and analysis of coal tar asphalt and to point out opportunities for improvement of the risk classification process.

In this project we propose a completely novel approach of soil remediation where As is immobilised and at the same time PAH are degraded in situ , i.e. without soil excavation. We will achieve this by modifying electrokinetic principles to fit our purpose.

The main objective of our project is to create a sustainable and cost-effective solution for managing PFAS-contaminated groundwater that can be applied on site at the source of contamination. To address this issue, we will build on our earlier achievements and continue developing solutions to break ...

Through the RE:SOURCE program funded by the Swedish Energy Agency, Vinnova and FORMAS, LTU's research groups for Waste Technology and Water Technology have been funded the project.

The main objective of our project is to create a sustainable and cost-effective solution for managing PFAS-contaminated groundwater that can be applied on site at the source of contamination.

Waste and materials management is about how sustainable systems can be developed for Kiruna municipality conditions.

Per- and polyfluoroalkyl substances (PFAS) are extremely stable chemical compounds, widely used in multiple applications and products worldwide.

Up until the beginning of the 70s roads were mostly built using asphalt with coal tar as binder, so called tar asphalt. This tar asphalt remains under the wear layer in many roads both in Sweden and abroad and contains PAH which is both an environmental hazard and cancerogenic.

In this international project funded by EU and China, we investigate the possibility of simultaneously immobilising metal(loid)s in situ and degrading organic contaminants (PAH) in soil using plants, mycorrhiza and electrochemistry.
