CEO’s greeting

Reflecting on the past year, I am pleased to acknowledge the significant progress we’ve achieved. Our strategic relocation to new premises in Jyväskylä in late 2023 was timely, accommodating the rising number of customer projects that demanded additional space and enhanced facilities for our technology development and growing team.
2024 has marked a period of intense activity and productivity for us. We successfully piloted our innovative 4D Scavenger® technology in recovering battery metals, won a prestigious water resource innovation challenge, and initiated multiple collaborations across all business focus areas. These accomplishments were driven by the exceptional collaboration and dedication within our skilled team, alongside the unwavering support from our diverse stakeholders.
The practical applications of our technology throughout the year have provided invaluable insights into generating the most economically viable customer and environmental value. The ongoing support from our investors and alignment with European goals for circular economy have been crucial in enabling us to concentrate on our core mission—developing solutions that benefit both our customers and the environment.
Thank you for your trust in our work.
