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.
Assessment of Sustainable Wastewater Treatment Technologies Using Interval-valued Intuitionistic Fuzzy Distance Measure-based Mairca Method
Researchers developed a decision-making framework for evaluating sustainable wastewater treatment technologies using fuzzy set theory and multi-criteria analysis. The method accounts for uncertainty in expert assessments while comparing technologies across economic, environmental, and social criteria. The study provides a systematic approach for selecting wastewater treatment solutions that can address emerging contaminants including microplastics.
Marine plastic pollution: A systematic review of management strategies through a macroscope approach
Researchers applied a systems-level framework to review 176 studies on marine plastic pollution management, finding that waste collection infrastructure and freshwater pathways are critically understudied and that no existing strategy — from beach cleanup to biomaterials — is scalable enough to meaningfully reverse the plastic crisis.
Evaluating the environmental impact of cleaning the North Pacific Garbage Patch
Researchers developed a novel plastic pollution impact assessment framework and applied it to evaluate whether cleanup operations targeting the North Pacific Garbage Patch could deliver a net environmental benefit, finding that removing legacy plastic pollution from the subtropical gyre may benefit marine life and carbon cycling when assessed against the environmental costs of the cleanup itself.
Global assessment of innovative solutions to tackle marine litter
Researchers reviewed 177 validated innovative solutions for preventing, monitoring, and cleaning marine litter from a global search, finding that most focused on monitoring rather than prevention, few had reached commercial maturity, and none had been validated for environmental impact or efficiency.
Plastic pollution solutions: emerging technologies to prevent and collect marine plastic pollution
Researchers created a comprehensive inventory of 52 technologies designed to either prevent plastic from entering waterways or collect existing marine plastic pollution. The study found that while many promising solutions exist, most target macroplastics and there are far fewer options for capturing microplastics. The inventory serves as a roadmap for policymakers and innovators to compare approaches and identify where more technological development is needed.
Life Cycle and Techno‐Economic Assessment of Microplastics Remediation Technologies and Policies
This chapter analyzes microplastic remediation technologies using life cycle assessment, techno-economic assessment, and SWOT analysis to compare their sustainability and cost-effectiveness. Researchers evaluated methods such as froth flotation, density separation, and electrostatic separation for removing microplastics from water. The study aims to help researchers understand which remediation approaches are most technologically and economically feasible without compromising environmental sustainability.

Análise de técnicas de remediação para a mitigação de micro e nanoplásticos em oceanos com base na revisão da literatura
This review analyzed scientific literature on remediation techniques for removing micro- and nanoplastics from ocean environments, identifying and comparing two key approaches: the first focused on membrane-based methods — ultrafiltration, membrane bioreactors, and dynamic membrane technology — for wastewater treatment, and the second examined nanomaterials as adsorbents. Membrane technologies demonstrated high removal efficiency for micro- and nanoplastics, though each method presents implementation challenges that require further research.
