Lemon Eucalyptus trees are a common species of economic value, they have a large amount of peeling each year, and the bark usually decays naturally without being used. According to the results of our research, the bark can inhibit the growth of molds. We mixed the material into the pulp to make recycled paper and used the paper's own latch and tenon structure. We made geometric containers through the radiating symmetric pattern of the cutting without any additional tools, while the paper was processed in multiple layers after the team's experiments to give it a certain degree of support.
