The story of SIEVE begins several years ago on a beach in Denmark when Sebastian collects plastic that has washed up on the shore. He then started to think about how to prevent plastic from getting into our oceans in the first place. And so he starts to form the idea of making some of his own surfing equipment, the surf fins, from recycled plastic himself, to offer a sustainable alternative to conventional surf fins and to advocate for the responsible use of plastic.
