At Foundation Why Knot, we take a fresh approach to invasive species. Instead of seeing them as a problem, we materialize Japanese Knotweed into circular, biobased materials and products.

By responsibly collecting and processing invasive plants, we reduce environmental impact, support biodiversity, and create sustainable materials with social and economic value.

We believe the future of design is built locally. By reconnecting with nature and restoring ecosystems, we create biobased products that contribute to a more diverse world.

Through collaboration with designers, researchers, and land managers, we turn ecological challenges into opportunities for innovation and circular design.
