In 2017, China implemented its National Sword policy, effectively halting the import of plastic waste—a practice that had allowed the country to process nearly 45% of the world’s plastic waste. This sudden shift left a major question: What happens to all that plastic now?
With limited international processing options, the burden of disposal has returned to domestic systems. In the United States alone, over 30 million tons of plastic waste are generated each year, yet only about 4.5% is recycled. The rest? It’s ending up in landfills, which are growing at an unsustainable rate.
This crisis has sparked innovation across industries. The asphalt sector is now exploring how it can be part of the solution by incorporating recycled plastics into pavement materials, reducing landfill waste while enhancing asphalt performance.
