Plastic production
• 85% plastic pellets (approx. 40% for packaging)• 65 million tonnes for textile fibres in 2016 (The Fiber Year 2017)

• Overall plastics into the oceans: 4.8-12.7 mio tonnes / year (Jambeck et al. 2015)• 0.8-2.5 mio tonnes of primary microplastics / year (Boucher and Friot (2017)• 15-31% of plastics into the oceans = primary microplastics Boucher and Friot (2017)• 4.83 trillions of microplastic particles afloat in the oceans (Eriksen et al. 2014)

• 98% of losses from land-based activities• Almost 50% end up in the oceans
