The construction industry has a significant climate footprint. To phase out fossil-based materials, more sustainable alternatives are needed. In the Nordic project MOBI –Moldable Ocean Biomass for Industry – Axfoundation is working with processors, designers, and material developers to explore whether seaweed from our oceans could be one of them. The goal is to demonstrate how this local and underutilized biomass can reduce climate impact without competing for valuable land – while also contributing to a more circular and bio-based economy in the Nordic region.
