Sustainable Corrosion Protection Using Recycled Plastic-Resin Coatings for Marine Applications

This project investigates the use of recycled plastic mixed with resin as a protective coating for steel against corrosion in marine environments. The study involved collecting plastic waste from the sea, grinding it into a fine powder, and mixing it with resin to form a composite coating. A total of 20 steel pieces were used in the study, where 10 pieces were coated and 10 remained uncoated. The coated and uncoated steel pieces were tested under real marine conditions and laboratory-controlled conditions using sea water. After every 15 days, samples were inspected for signs of corrosion and degradation. The results revealed the potential of using plastic waste for protective coatings in marine applications, with promising outcomes for reducing corrosion on coated steel surfaces. This project investigated the feasibility of utilizing recycled sea plastic as a reinforcement material in resin-based protective coatings for marine applications. Plastic waste collected from coastal areas was processed into powder and incorporated into a resin matrix, which was then applied to steel substrates. The performance of this navel coating was evaluated through real-sea exposure and laboratory seawater immersion tests, comparing coated and uncoated steel samples. Results demonstrated that the recycled plastic-resin coating significantly enhanced the corrosion resistance of steel in marine environments, offering a sustainable solution for both plastic waste management and marine infrastructure protection.
