Plastic is accumulating far faster than recycling systems can process it. Over 400 million tonnes of plastic are produced worldwide each year, and only about 9% of it is recycled; the rest is landfilled, incinerated or released into the environment. According to US statistics, landfills accepted about 27 million tons of plastic waste in 2018, which is almost one-fifth of all municipal solid waste that was produced in that year. The problem with roads is quite different; however, the two issues share a common link: asphalt, which is bound together by bitumen, a fossil‑fuel derivative. The asphalt on roads in hot states such as Texas cracks and ruts in high heat.
