Plastic to outweigh fish in oceans by 2050, study warns

19 January 2016
By David Williams (PhysOrg) – Plastic rubbish will outweigh fish in the oceans by 2050 unless the world takes drastic action to recycle the material, a report warned Tuesday on the opening day of the annual gathering of the rich and powerful in the snow-clad Swiss ski resort of Davos. An overwhelming 95 percent of plastic packaging worth $80-120 billion (73-110 billion euros) a year is lost to the economy after a single use, said a global study by a foundation fronted by yachtswoman Ellen MacArthur, which promotes recycling in the economy. The study, which drew on multiple sources, proposed setting up a new system to slash the leaking of plastics into nature, especially the oceans, and to find alternatives to crude oil and natural gas as the raw material of plastic production. At least eight million tonnes of plastics find their way into the ocean every year—equal to one garbage truckful every minute, said the report by the Ellen MacArthur Foundation, which included analysis by the McKinsey Centre for Business and Environment. “If no action is taken, this is expected to increase to two per minute by 2030 and four per minute by 2050,” it said, with packaging estimated to represent the largest share of the pollution.

19 January 2016 (Ellen MacArthur Foundation) – Applying circular economy principles to global plastic packaging flows could transform the plastics economy and drastically reduce negative externalities such as leakage into oceans, according to the latest report by the World Economic Forum and Ellen MacArthur Foundation, with analytical support from McKinsey & Company. The New Plastics Economy: Rethinking the future of plastics provides for the first time a vision of a global economy in which plastics never become waste, and outlines concrete steps towards achieving the systemic shift needed. The report, financially supported by the MAVA Foundation, was produced as part of Project MainStream, a global, multi-industry initiative that aims to accelerate business-driven innovations to help scale the circular economy. The new report acknowledges that while plastics and plastic packaging are an integral part of the global economy and deliver many benefits, their value chains currently entail significant drawbacks. Assessing global plastic packaging flows comprehensively for the first time, the report finds that most plastic packaging is used only once; 95% of the value of plastic packaging material, worth $80-120 billion annually, is lost to the economy. Additionally, plastic packaging generates negative externalities, valued conservatively by UNEP at $40 billion. Given projected growth in consumption, in a business-as-usual scenario, by 2050 oceans are expected to contain more plastics than fish (by weight), and the entire plastics industry will consume 20% of total oil production, and 15% of the annual carbon budget. […] Plastic packaging generates significant negative externalities, conservatively valued by UNEP at USD 40 billion and expected to increase with strong volume growth in a business-as-usual scenario. Each year, at least 8 million tonnes of plastics leak into the ocean — which is equivalent to dumping the contents of one garbage truck into the ocean every minute. If no action is taken, this is expected to increase to two per minute by 2030 and four per minute by 2050. Estimates suggest that plastic packaging represents the major share of this leakage. The best research currently available estimates that there are over 150 million tonnes of plastics in the ocean today. In a business-as-usual scenario, the ocean is expected to contain 1 tonne of plastic for every 3 tonnes of fish by 2025, and by 2050, more plastics than fish (by weight).
