    "title": "Seabin - Floating Garbage Collection Device",
    "inventor_name": "Andrew Turton & Pete Ceglinski",
    "publication_year": 2015,
    "device_name": "Seabin",
    "goal": "Continuously collect floating debris and oil from marinas, ports, and other water bodies to reduce marine pollution.",
    "problem_addressed": "Marine and freshwater water pollution caused by floating garbage, oil, and other contaminants.",
    "concept_summary": "A floating container fixed to a dock uses a shore-powered pump to draw water through a natural-fibre catch bag. The bag captures debris while the water is returned to the marina. An optional oil/water separator can be added.",
    "detailed_description": "The Seabin is installed just below the water surface on a floating dock. A shore-based electric pump creates a flow of water into the bin, pulling in floating rubbish. The debris is trapped in a natural-fibre catch bag attached to the top of the container by elastic fastenings. Water is then suctioned out the bottom of the bin and pumped back to the marina. The system can be equipped with an oil/water separator to collect fuel oil, gasoline, or other fluids. The device is designed for marinas, ports, yacht clubs, lakes, rivers, and ponds, and operates 24/7 with low maintenance.",
