‘50 : plastic industry Gobal annual production : 260 Mt Plastic = 10% of our garbage = 260 million x Plastic
3
DUMP Ends up in the OCEAN Problem
4
Total surface in oceans occupied by plastic => 700 000 km² (~France) - 15 000 000 km² Highest accumulation : Northern Hemisphere high population density industry prosperity Problem
5
Impact FAUNA At least 267 different species are known to have suffered from entanglement or ingestion of marine debris
6
Impact CORAL REEFS Damaged by dumped fishing material (nets) Eg : Coral reef N-W of Hawaï ->1996-2006 : 511 ton fishing material removed
7
First established in ‘60 1974 : British Plastics Federation and a Fellow of the Plastics Institute, stated that ‘‘plastics litter is a very small proportion of all litter and causes no harm to the environment except as an eyesore’’ => ETHICAL ISSUE Awareness
8
MARINE DEBRIS = 60% - 80% plastic (!) TOURISM (!) FISHERY 15% ends up on beaches- polystyrene in fish -> poison - damaged ecosystems -> less fish Development
9
Breakdown : photo degradation (Nivea, Colgate, L’Oreal, Garnier, Gillette, Clearasil, Johnson & Johnson, Ikea, Biotherm, Albert Heijn and Aldi) + heat & light MICROPLASTICS (< 5mm) MACROPLASTICS Development SCRUBSTOOTHPASTE
10
MICROPLASTICS How small are they ? Can they be filtered out ? => (!) End up in human food chain (!) What are the consequences ? -> human health ? => Can threaten human health => Becoming an important issue Microplastics
11
‘86 : International Coastal Cleanup -> local effort for one day each year “Clean-Up the World” (UNEP) Marine Conservation Society (NGO) National Oceanic and Atmospheric Administration (US government) Solutions ?
12
Recent : The Ocean Cleanup Array -> Boyan Slat (19 years old) ‘Passive clean up’: - array of floating barriers fixed to the sea bed - using the natural circulation period - extracted plastic => energy, oil, new materials (!) GOAL : Extract 7 250 000 kg of plastic from the oceans in just 5 years Solutions ?
13
Most important = handle source (!) Radically reduce influx of new plastic pollution HOW ? Solutions ?
