Eucalyptus trees are growing in Portugal also in the cities and the smell of it is in the air everywhere. The long and wavy bark that peels naturally from the trees and is lying all over the ground, aroused our interest. A process of material preparation for eucalyptus bark was invented based on criteria of regenerative design. To maintain its compostable and natural qualities, we use a starch-based binder. The resulting material is lightweight and durable once dried. It can be dissolved in water, for reuse and reshaping to allow long-life-circles. EUCA wood contains 100% natural components.
