Research status and prospect of microplastics in ship grey water
Summary
This review examines microplastic pollution in ship grey water, covering potential sources, current management measures, and progress in qualitative and quantitative analysis techniques for characterizing marine grey water microplastics. The authors propose future research directions including standardized analytical frameworks and improved estimation methods for marine plastic inputs from vessels.
This paper deeply discusses the microplastic pollution of ship gray water which is getting more and more attention at present. This paper begins with an overview of the potential sources of microplastics and the current management measures. Then, the research progress on the qualitative and quantitative analysis techniques of Marine gray water microplastics, Marine input estimation and type distribution of microplastics in domestic and foreign literature is reviewed in detail. On this basis, the paper puts forward suggestions for future research directions, including establishing the analysis method of gray water composition based on actual ships, strengthening the research on the basic data of microplastics, formulating the inventory of gray water microplastics discharge from ships, and promoting the improvement and development of the control policy of gray water discharge from ships. These suggestions aim to provide scientific basis and strategic guidance for the treatment of ships' grey water microplastics pollution.

Assessment of Microplastic Abundance and Discharge from Greywater of Ships
Researchers quantified microplastics in ship greywater from showers, washbasins, laundry, and dishwashers and found that laundry sources produced the highest microplastic concentrations. Since greywater can be discharged to the sea without treatment in most areas, ships contribute substantially to marine microplastic pollution. The study supports the case for regulating greywater discharge from vessels.
Microplastic generation and emission from ship's greywater
Researchers measured microplastic abundances and characteristics in greywater from different vessel types — a research vessel, a container ship, and passenger ships — and estimated global microplastic emissions from the discharge of untreated ship greywater. They found a mean abundance of 135,563 particles/m3 in research vessel greywater with fibers comprising about 66% of particles, identifying greywater discharge as a significant and largely unregulated sea-based microplastic source.
Microplastic generation and emission from ship's greywater
Researchers investigated microplastic concentrations and characteristics in greywater discharged from three vessel types - a research vessel, a container ship, and passenger ships - and estimated total microplastic emissions from global commercial shipping. The study found that untreated ship greywater represents a significant but unregulated sea-based microplastic source, with passenger vessels generating the highest microplastic loads per volume of discharge.
Occurrence and characteristics of microplastics in greywater from a research vessel
Microplastics were found in greywater from a research vessel across multiple water usage types, with laundry water showing the highest microplastic concentrations, identifying ships as an underappreciated sea-based source of microplastic 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.
