Weeefiner Oy is a Finnish deep-tech company that has developed the groundbreaking 4D Scavenger® technology, enabling the recovery of valuable metals and nutrients from industrial wastewater. Instead of losing these materials during water treatment, companies can recover them and reuse them in production or sell them as raw materials. In this way, Weeefiner transforms waste into a resource and helps companies both reduce environmental impact and strengthen their business.
Weeefiner Oy was awarded the Nordic Innovation Award 2026 among five finalists from across the Nordic countries.
The Nordic jury highlighted that Weeefiner’s technology combines resource efficiency and environmental protection while also delivering measurable business benefits. The solution has demonstrated its potential in practice, opens up new revenue streams, and contributes to significant environmental improvements. Moreover, the company has shown a strong focus on the protection of intellectual property rights, which ultimately led to the jury’s unanimous decision to name Weeefiner Oy the winner of the Nordic Innovation Award 2026.
The Danish finalist, Sonus Fishery, with co-founder and CTO Jan Muller, reached the final as Denmark’s representative in the Nordic Innovation Award. The company was nominated for its patented, sound-based solution, which has the potential to make trawl fishing more environmentally sustainable.
The Danish jury highlighted Sonus Fishery’s breakthrough acoustic technology, which uses sound to guide fish movement and reduce bycatch. The sound generated by the invention creates a “virtual net”, extending the effective range of the trawl while simultaneously reducing the need for physical contact between the seabed and fishing gear.
