ClearAn Ecological Sustainability Assessment Approach for Strategic Decision Making in International Shipping
This paper develops an ecological sustainability assessment framework for international shipping, examining pollution, biodiversity impacts, and resource use. While not focused on microplastics specifically, shipping is a significant source of marine plastic pollution through cargo spills, lost fishing gear, and ship-generated waste. Incorporating plastic pollution into shipping sustainability assessments could help reduce this contribution.
Optimizing waste management for green shipping: industry commitment through participatory processes in Cyprus
Not relevant to microplastics — this study presents a multi-stakeholder participatory process (DeCyDe-4-Shipping) used in Cyprus to identify consensus actions for reducing plastic waste and improving waste management in the shipping industry, focused on marine litter policy rather than microplastic science.
A multi-criteria assessment of the implementation of innovative technologies to achieve different levels of microplastics and macroplastics reduction
This study applied a multicriteria decision analysis framework to evaluate innovative technologies for reducing microplastic and macroplastic pollution in marine environments, ranking cleanup measures by environmental, socioeconomic, and financial impact to inform better policy decisions.
Multi-Criteria Relationship Analysis of Knowledge, Perception, and Attitude of Stakeholders for Engagement towards Maritime Pollution at Sea, Beach, and Coastal Environments
Researchers used multi-criteria analysis to assess the knowledge, perceptions, and attitudes of stakeholders toward marine pollution governance, finding persistent gaps between awareness and action, and identifying barriers to mobilizing the level of engagement needed for effective protection of vulnerable coastal ecosystems.
Investigation of plastic and microplastic waste from ships in the marine environment
Researchers investigated plastic and microplastic waste originating from ships in the marine environment, examining the types, quantities, and pathways by which vessel operations contribute to marine plastic pollution. The study addresses a relatively underexplored source of marine plastic contamination compared to land-based inputs.
Assessing the Selection of PET Recycling Optionsin Japan: Multi-Criteria Decision Analysis
This study examines PET plastic recycling options in Japan using a multi-criteria decision analysis (MCDA) framework, set against the global context in which only 9% of plastic waste is recycled and 22% bypasses proper waste management. The analysis evaluates competing recycling pathways to identify the most sustainable and economically viable approaches for managing Japan's PET waste streams.
Development Measures to Enhance the Ecological Safety of Ships and Reduce Operational Pollution to the Environment
This study develops measures to enhance ecological safety of ships and reduce operational pollution, addressing exhaust emissions, waste and ballast water discharge, and accident prevention through legislative, organizational, and technical approaches.
Evaluating the net environmental impact of removing plastic pollution from the North Pacific Garbage Patch
Researchers conducted a lifecycle assessment to evaluate the net environmental impact of removing legacy plastic pollution from the North Pacific Garbage Patch, weighing the ecological harm reduction from plastic removal against the environmental costs of cleanup operations including fuel consumption and bycatch. The study found that ocean plastic cleanup can deliver a net environmental benefit when operations are optimised, but that the balance depends critically on vessel efficiency, cleanup technology, and the degradation state of targeted plastics.
Wastewater Treatment and Multi-Criteria Decision-Making Methods: A Review
This review assessed the application of multi-criteria decision-making methods to wastewater treatment, identifying approaches that balance technical, economic, environmental, and social factors. The synthesis aims to support evidence-based selection of treatment technologies aligned with sustainability goals.
Strategies for Green Shipbuilding Design and Production Practices Focused on Reducing Microplastic Pollution Generated during Installation of Plastic Pipes
This paper proposes that shipbuilders should account for microplastic pollution during the design and fitting-out stages of vessel construction, particularly when cutting and preparing plastic pipes — a process that scatters plastic debris that can easily enter the marine environment. By choosing pipe layouts that minimise cutting and handling near open water, the shipbuilding industry could meaningfully reduce its contribution to ocean microplastic pollution.
Consumer-based actions to reduce plastic pollution in rivers: A multi-criteria decision analysis approach
Researchers applied multi-criteria decision analysis to evaluate consumer-based actions for reducing macroplastic pollution in European freshwater environments, focusing on commonly found single-use plastic items. The analysis ranked actions by their potential to reduce plastic inputs to rivers, providing a framework to guide consumer choices and inform policy targeting the most impactful plastics.
Decision-science navigates trade-offs between environmental and socio-economic objectives for marine debris mitigation
Researchers applied decision-science methods to evaluate marine debris management strategies across Southeast Asia, balancing environmental protection with socio-economic impacts. They found that structured decision-making helped identify the best sites and approaches for reducing plastic exposure to marine ecosystems and coastal communities. The study demonstrates how systematic frameworks can navigate the complex trade-offs involved in tackling ocean plastic pollution.
Microplastics in Ship Sewage and Solutions to Limit Their Spread: A Case Study
Researchers found microplastic particles in both grey water and post-treatment sewage from transport ships, with mean concentrations of 72 particles per litre in grey water and 51 per litre in treated sewage, demonstrating that ships represent a significant and underregulated source of microplastic pollution in protected marine areas.
Comparative Analysis of Environmental, Economic, and Social Criteria for Plastic Recycling Technology Selection in India, Sri Lanka, Pakistan, and Thailand
This study surveyed stakeholders in four Asian countries about criteria for selecting PET plastic recycling technologies, finding that environmental and economic factors were rated highest. Improving PET recycling capacity is critical for reducing plastic waste that ultimately becomes microplastic pollution.
A Cross Disciplinary Framework for Cost-Benefit Optimization of Marine Litter Cleanup at Regional Scale
This paper presents a cost-benefit framework for prioritizing where and how to clean up marine litter at regional scale. The framework considers factors like litter type, removal cost, ecological damage, and population exposure. Better economic tools for prioritizing cleanup could help direct limited resources toward areas where marine plastic removal has the greatest benefit.
Site selection within the maritime spatial planning: Insights from use-cases on aquaculture, offshore wind energy and aggregates extraction
This paper reviews how maritime spatial planning frameworks incorporate competing ocean uses such as aquaculture, offshore wind energy, and aggregate extraction, presenting case studies to illustrate site selection challenges and multi-use conflict resolution.
Polymer prioritization framework: A novel multi-criteria framework for source mapping and characterizing the environmental risk of plastic polymers
Researchers developed a multi-criteria framework for ranking the environmental risk of plastic polymers, finding that polyvinyl chloride, polypropylene, and polystyrene posed the highest risk, with packaging and construction sectors as dominant sources.
Plastic litter in life cycle assessment: Advances of the marine impacts in life cycle assessment international taskforce and application to case studies
