    2008年12月5日第63届联合国大会通过第111号决议,决定自2009年起,每年的6月8日为“世界海洋日(World Oceans Day)”。

    2019年世界海洋日的主题是“性别与海洋(gender and oceans)”。




    The Seabin project

    Invented by two Aussie surfers, the Seabin is pretty much exactly what you think: it’s a large flowerpot-shaped container that captures everything from plastic bottles, bags and utensils, as well as trash as small as 2mm. A pump at the bottom of the bin sucks in water and rubbish, which are then separated by a mesh unit inside. The water is then released, while the trash is recycled.


    The seabins are fitted around marinas and coasts, trapping rubbish before it can make its way into the ocean proper. According to the Seabin website, each bin can catch 90,000 plastic bags a year, nearly 36,000 disposable cups, 16,500 plastic bottles and 166,500 plastic utensils. There are over 700 Seabins located around the world, with many concentrated along the coasts of European countries.

    Recycling Technologies

    Capturing plastic in the oceans is one thing, but what to do with it once it’s back on land? According to the UN, less than one tenth of plastic produced gets recycled. However, one UK company has come up with an ingenious way of dealing with types of plastic that are ‘unrecyclable’— before they even make it into our waters.


    Rather than let many types of plastic get sent to landfills, be incinerated or exported, Recycling Technologies has come up with another solution: melt it, and then turn it into an oil that can then be turned into everything from new packaging to wax for waterproofing, product surface coating and more.

    Plastic-eating enzyme

    An innovation that has a profound impact on plastic was created completely by accident. Back in April 2018, scientists announced that they inadvertently created an enzyme called PETase that can break polyethylene terephthalate (PET) plastics down to its original chemicals.


    inadvertently['ɪnəd'vɝtntli]:adv. 无意地,不经意地

    enzyme['ɛnzaɪm]:n. [生化] 酶


    This is seen as a breakthrough because PET, which is used to make packaging by the food and drink industry, is extremely hard to break down into a state that would allow it to be recycled into other high-quality plastic products, instead coming out as a lower-grade and therefore less-valuable product. This means that new high-quality plastic packaging still has to be made.


    However, with the discovery of PETase, it is hoped the recycling loop can be closed so that old PET products get recycled into products of the same high-quality.




    Referred to as the ‘Wall-E of the water’ the WasteShark is an aquadrone that sucks up garbage from the water.


    Created by RanMarine, a Dutch environmental technology company, the WasteShark was initially deployed in the Dubai Marina. It can swim for up to 16 hours and consume as much as 1,100lbs of trash.


    It collects everything from floating trash, plastic and even microplastic. It has sensors that measure everything from pH, nitrate, water salinity and chloride. Once the trash is collected, the aquadrone delivers it to the collection point.



    PlanetCare’s washing machine filter

    PlanetCare approaches the issue of ocean pollution from a different angle. Rather than dealing with the plastic pollution that has already made it out into the open water, the Slovenian company designed a product that tackles it at source.


    The company’s focus is microfibres on items of clothing such as fleeces. These strands, as small as 0.5mm are too small to be captured by machine wash filters, and ultimately make their way into the ocean, where they are mistaken for food by marine life. The fish can then suffocate on the fibers which can also attract toxins.


    PlanetCare has created a special washing machine filter that is designed to capture the fibres shed from clothes during washes, which can add up to as many as 700,000 per average 6kg wash.
