GreenWave – a US-based vertical ocean farming solution – has won the Sustainia Award. GreenWave’s revolutionary technology allows ocean farmers to produce 30 tons of sea vegetables and 250,000 shellfish per acre in a year while restoring ocean ecosystems. Sustainia handed over the Sustainia Award to Bren on Wednesday February 8, at Sustainia’s big Sustainia Living event at the Royal Danish Opera House in Copenhagen.
One of the Film4Climate Global Video Competition winning entries "Three Seconds" (1st Prize Short Film) was showcased at this Sustainia event.
Fed up with the unsustainable practices of the fishing industry, fisherman Bren Smith founded GreenWave just three and a half years ago on Long Island, New York, U.S. GreenWave relies on a new innovative system, which enables seaweed, scallops and mussels to grow on floating ropes, stacked above oyster and clam cages below. The system provides food, fertilizer, animal feed and sustainable biofuels, making ocean farmers the stewards of their local waters. Bren Smith now has 15 farms in development in Connecticut, New York, Rhode Island, Massachusetts, and California.
GreenWave represents a readily scalable and replicable solution, which takes a triple bottom line approach – one that builds a blue-green economy, acts on climate change, and provides better food options – while addressing the global goals, making it a clear recipient for the Sustainia Award.
