Papweed is the result of extensive research linked to the world in which we live, threatened by the anthropic impact that undermines natural systems and our balances. Papweed is intended as an interactive process with the material that becomes capable of self-organizing and allowing generative vitality. Papweed combines two worlds that I have studied: Paper (paper) + Algae (algae), thus creating a new material, modelable and flexible, totally compostable. An example of circular design able to respond to different design needs, from packaging, to packaging, to product design.
