SLU Workshop: Microplastics and their role in the use of sludge on land

Is wastewater sludge an important contributor of microplastics in agricultural soils? Are plastics harmful to our soils? Welcome to a FORMAS and EJP SOIL funded workshop on the role of plastics when managing sludge reuse on land. We gather actors from the industry, public service, quality certification organisations and academia to discover advances in this discussion and identify knowledge gaps to work with in the coming years.

When? 24 November, 10.00 – 16.00 (registration from 09.30)
Where? Uppsala, Campus Ultuna
Cost? For free, lunch and coffee will be offered.
Register: Fill out the form below.
Note: We will also arrange for participation via videolink (zoom or similar) but this will only apply to plenary sessions.

Wastewater treatment sludge in bio-based societies

Using wastewater treatment plant sludge on agricultural soils is an ideal way of closing nutrient cycles and returning carbon to soils. Sludge reuse thus features high on the agenda of countries seeking to become bio-based societies. However, several contaminants such as microplastics from sludge may contaminate agricultural soils and end up in our food chain. The Swedish government has even considered banning the use of sludge on land all together.

Since the information is limited or conflicted on how hazardous plastics are to soil biota and how plastics behave in soils, it is currently unclear what importance microplastics in sludge should have considering restrictions or bans on using sludge to fertilize agricultural land.

Furthering discussions

The Department of Soil and Environment is currently running FORMAS and EJP SOIL funded projects on the fate of microplastics in agricultural soils. During this workshop, we aim to report our project results, share knowledge and discuss ways forward.

We will be joined by both national and international speakers who will present the most recent insights in microplastic measurement, hazards, and fate in soils. By involving these speakers with actors from industry, public service and certification organisations, we aim to spur discussions to bring clarity on the issue and identify where research should do better to fill relevant knowledge gaps.
