Chief Sustainability Director at Ragn-Sells Pär Larshans will take part in the seminar Circular Aquaculture for Sustainable Food Production, focusing on the environmental challenges linked to aquaculture and the opportunities created through circular value chains. The program addresses the current state of fjords, the impact of sludge on marine ecosystems, and how nutrients such as phosphorus and nitrogen can be recovered and reused rather than lost to the sea - areas where EasyMining’s technologies play an important enabling role.

EasyMining’s CEO Jan Svärd will participate in the seminar Technology and Systems Innovations highlighting how emerging technologies and collaborative initiatives can enable circular value chains within aquaculture. He will take part alongside other industry and technology representatives to showcase how system-level solutions can transform aquaculture sludge into valuable resources and support a circular transition in food production systems.

EasyMining and Ragn-Sells are also involved in broader collaborative efforts, including the EU-funded Aquaphoenix project, that contributes to reducing aquaculture emissions and valorising fish sludge by recovering phosphorus and nitrogen, supporting the transition to circular aquaculture.

“To make aquaculture truly sustainable, we need system-level solutions that turn unavoidable by-products into valuable resources. By recovering nutrients that are essential for food production, we can reduce pressure on nature while strengthening long-term food security,” says Jan Svärd.

Aquaculture plays a crucial role in meeting future food demand, while facing increasing pressure related to environmental impact and resource use. Nutrient leakage from fish farming affects fjords and coastal ecosystems, while critical raw materials such as phosphorus are lost instead of being returned to productive use. Through circular aquaculture - supported by technologies developed by EasyMining and initiatives such as Aquaphoenix - nutrients can be recovered and reintroduced into the food system, supporting both food security and ocean health.
