Annual production of fossil fuel-based plastics is set to top 1.2 billion tonnes by 2060 and waste to exceed 1 billion tonnes, according to a report by the Organisation for Economic Co-operation and Development (OECD).
The report said this increase will be driven by economic and population growth, the largest increases are expected in emerging economies in sub-Saharan Africa and Asia.
According to the OECD even with aggressive action to cut demand and improve efficiencies, plastic production would almost double in less than 40 years.
Such globally coordinated policies, however, could hugely boost the share of future plastic waste that is recycled, from 12 to 40 percent.
There is increasing international alarm over volume and omnipresence of plastics pollution, and its effect.
The debris is estimated to cause the deaths of more than a million seabirds and more than 100,000 marine mammals each year.
Plastic pollution is one of the great environmental challenges of the 21st century, causing wide-ranging damage to ecosystems and human health.
Since the 1950s, roughly 8.3 billion tonnes of plastic have been produced with more than 60 percent of that tossed into landfills, burned or dumped directly into rivers and oceans.
Some 460 million tonnes of plastics were used in 2019, twice as much as 20 years earlier. The amount of plastic waste has also nearly doubled, exceeding 350 million tonnes, with less than 10 percent of it recycled.
Currently, nearly 100 million tonnes of plastic waste is either mismanaged or allowed to leak into the environment, a figure set to double by 2060.
