Plastic pollution is a major environmental challenge that poses a direct threat to sustainable development and, ultimately, our livelihood. When no longer useful, plastics are often destined for incineration or landfills. Much of the plastic waste ends up in the oceans, harming marine life and potentially contaminating the seafood we eat. Nuclear techniques can help monitor and reduce plastic waste.
“The times we are living – as we are still struggling with the pandemic – have confirmed to all of us in a powerful and painful way that global problems need global solutions. We can only solve big issues when we come together,” said IAEA Director General Rafael Mariano Grossi, during a roundtable discussion today with partners in Asia and the Pacific region.
More than 340 participants from countries across Asia and the Pacific attended the event. They included users of nuclear technologies and environmental experts from industry, academia and international organizations. The event was the first of a series of roundtables that provide a platform to discuss ongoing efforts, innovative solutions and partnerships to confront plastic pollution.
Of all plastic produced since 1950 to 2015, only 9 per cent has been recycled, and about 17 per cent remains in use, according to a study published in Science Advances. Leaving the remaining bulk to landfills (60 per cent) that contaminate downstream ecosystems, such as rivers, groundwater and eventually the ocean, and incineration (12 per cent), which often releases toxic gases. By 2025, the ocean will contain one tonne of plastic for every three tonnes of fish, and by 2050, there may be more plastic in the ocean than fish, according to projections.
The IAEA is at the forefront of deploying nuclear science and technology to address global challenges, including for plastic pollution. “Nuclear techniques can help in assessing and understanding the dimension of the problem … but also in the recycling of plastic through radiation techniques, which allow us to produce materials that can be further used in the concept of a circular economy,” Mr Grossi said.
