On 16-17 September 2026, we exhibited at Smart City Expo Poland at EXPO XXI in Warsaw as part of the GreenEvo program’s promotional activities. It was a great opportunity to showcase our GreenEvo-awarded solution, the SYMBIO Biomonitoring System, at an event dedicated to innovative technologies for smart and safe cities. As usual, our mussels attracted considerable interest and sparked many interesting conversations. Thank you to everyone who stopped by our stand, intrigued by the mussels and curious to learn more about SYMBIO. The many presentations and conversations showed just how much interest there is in protecting drinking water intakes.
