Sources and Leakages of Microplastics in Cruise Ship Wastewater

To date, the contribution of sea-based sources to global marine litter and plastic pollution problem remains poorly understood. Cruise ships produce large amounts wastewater concentrate their activities in fragile ecologically valuable areas. This paper explores for first time microplastics cruise ship wastewater, as well pathways from source sea. It thereto uses a novel approach identification pathways, based on scientific literature microplastic operations management questionnaire among lines. The study highlights personal care cosmetic products, cleaning maintenance products synthetic microfibers released textiles laundry relevant categories. Untreated grey water overboard discharge biosludge, resulting treatment sewage water, were identified key pathways. lines can reduce emissions by adapting purchasing policies care, cosmetic, professional textiles. In addition, holistic all streams waste is essential prevent leakages vulnerable coastal ecosystems. Furthermore, be used guide company-level assessments modified address other maritime sectors.
