Three nations, three ways to recycle plastic waste with nuclear technology
Plastic waste pollutes oceans, streams, and bloodstreams. Nations in Asia and the Pacific are working with the International Atomic Energy Agency through the Nuclear Technology for Controlling Plastic Pollution (NUTEC Plastics) initiative to tackle the problem. Launched in 2020, NUTEC Plastics is focused on using nuclear technology to both track the flow of microplastics and improve upstream plastic recycling before discarded plastic can enter the ecosystem. Irradiation could target hard-to-recycle plastics and the development of bio-based plastics, offering sustainable alternatives to conventional plastic products and building a “circular economy” for plastics, according to the IAEA.

A simplified but approximate method for the calculation of nuclear heating is described. Results using this method are compared with those of more rigorous calculations. The computational effort required is significantly reduced, and an accuracy generally better than ±20% can be achieved provided reasonable estimates of gamma-ray production are used. It would appear that the gamma-ray absorption coefficients used here are too low as a result of assuming average gamma-ray energies that are too high. As experience is gained with use of the method, greater accuracy should result from improved assumptions regarding both gamma-ray production and average gamma-ray energies.
