Marine Litter and the Circular Economy

AI summary Read the abstract

This study analyzed the sources of marine litter in Croatia and examined how circular economy principles could help reduce plastic waste entering the Adriatic Sea. The findings indicate that Croatia needs more proactive policies linking packaging reduction, bioeconomy integration, and improved waste management systems to meet environmental and economic goals.

Marine litter has been identified as one of major threats to marine ecosystems due to its environmental, economic, safety, health, and cultural impacts. The paper analyses the sources of marine litter and the obstacles to resolving the issue of pollution by marine litter. It addresses the quality of the national waste management concept as well as the efficiency of its implementation in the Republic of Croatia where the Adriatic Sea is subject to substantial pressure from littering. Resolving the problem of marine litter means adopting appropriate policy regarding waste generated at sea, marinas, cruising and fishing, and at land in line with circular economy principles. Findings of the study show that the country should be proactive in adopting policies to reduce and modify packaging and link the bioeconomy to the circular economy in achieving environmental and economic benefits in terms of materials and energy efficiency. Further research concerning all Mediterranean countries should integrate, in a holistic manner, municipal waste management, food packaging and food waste, marine litter, tourism, local agriculture, and local economies.

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.

Marine litter in the Croatian part of the middle Adriatic Sea: Simultaneous assessment of floating and seabed macro and micro litter abundance and composition.

AI summary Read the abstract

Floating and seabed macro- and micro-litter in the Croatian middle Adriatic Sea were simultaneously surveyed, finding average floating micro-litter concentrations of 127,000 particles per square kilometer and seabed micro-litter of 36 particles per 100 g dry weight. The study confirms that plastic pollution is widespread at all depths in this semi-enclosed Mediterranean sea.

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.
