Tackling Marine Plastic Pollution Through Source-To-Sea Approach and Circular Economy
AI summary Read the abstract
This paper reviews the global problem of marine plastic pollution through a source-to-sea lens and proposes circular economy principles as a path toward solutions. It discusses policy instruments, extended producer responsibility, and international cooperation needed to address marine plastic litter.
Marine litter and associated marine pollution are becoming a complex global environmental hazard these days. Among the different faces of marine pollution, by far the largest and probably the most dangerous part is marine plastic litter. Plastic litter can be found in almost every marine environment in the world, including deep ocean beds and frozen polar ice. Unless new sustainable methods of plastic production and waste management are encouraged, marine plastic pollution will continue to pose a severe threat to the natural ecosystems of the world. In this paper, the status of marine plastic litter is reviewed using a DPSIR framework, and it is found that significant changes in the way we live and consume are needed to prevent it. A framework that combines the source-to-sea approach and circular economy is introduced as a possible solution to eliminate plastic waste from the environment as well as from the economy.

An Overview of the Current Trends in Marine Plastic Litter Management for a Sustainable Development
AI summary Read the abstract
This review summarizes current knowledge about marine plastic litter, from its land-based origins to its distribution across ocean environments, and evaluates recovery and recycling strategies. Researchers found that while technologies for collecting and recycling marine plastics are advancing, significant economic and logistical barriers remain. The study emphasizes that a circular economy approach, combining prevention, collection, and material recovery, is essential for addressing ocean plastic pollution.
Circular economy measures to keep plastics and their value in the economy, avoid waste and reduce marine litter
AI summary Read the abstract
This policy-oriented paper examines how circular economy measures — including improved collection, reuse, and recycling of plastics — can reduce marine litter and keep plastic materials and their economic value in the economy rather than allowing them to leak into marine environments.
Marine litter: how to monitor, reduce and prevent ocean debris. Focus on plastics and microplastics.
AI summary Read the abstract
This report reviewed the growing problem of plastic pollution in the oceans and the policy landscape for addressing it, emphasizing that production, use, and end-of-life management all require reform. It frames plastic pollution as a systemic challenge requiring coordinated international action rather than single-issue solutions.
Circular economy measures to keep plastics and their value in the economy, avoid waste and reduce marine litter
AI summary Read the abstract
This review argues that circular economy measures — including improved collection, reuse, recycling, and design for end-of-life — are necessary to keep plastic value in the economy while reducing the estimated 5-15 million tonnes of plastic entering oceans annually. Researchers present a framework of policy and industry measures to transition away from the current linear 'make-use-dispose' model that drives marine litter accumulation.
