There were millions of tonnes of plastic waste poured into the ocean on the earth every year. Inspired by coral growth, we maximize the reuse of those plastics wastes. Turn them into the “parts” of the reefs, which combine the plastics and coral reefs. While cleaning the ocean, those reefs also create the underwater habitat providing biological diversification. We reuse the abandoned offshore oil rigs left in the ocean to collect the floating wastes to construct the reefs. Those platforms regain the vitality and share their energy to activate life underwater.
