Marine Plastic Waste: Understanding the Challenge and Paths Forward

When talking about marine plastic waste, any plastic debris that ends up in the ocean, from large bottles to tiny fibers. Also known as ocean plastic litter, it threatens marine life, tourism and the climate. Plastic pollution, the broader flow of plastic into rivers, streets and seas fuels this problem, while microplastics, particles smaller than 5 mm that slip through filters and enter food chains make the issue almost invisible but deeply harmful.

Marine plastic waste intersects with several key concepts. First, ocean waste management involves collection, recycling and prevention strategies that target ports, beaches and offshore platforms. Second, the circular economy, a system that keeps materials in use through reuse, repair and recycling offers a framework to design products that never become litter. Third, marine biodiversity suffers as turtles, seabirds and fish mistake plastic for food, leading to injury or death. Finally, policy actions—like bans on single‑use packaging and extended producer responsibility—link the waste stream to industry behavior.
