Korea to melt instant noodle cups to produce petrochemical feedstock

“For decades, the empty, broth-stained polystyrene cup that once held instant noodles was viewed by Korean sanitation officials as an intractable environmental nuisance. Too heavily contaminated by spicy oil to be processed by traditional mechanical recycling, millions of these lightweight containers were destined for the incinerator or the landfill, a stubborn byproduct of the nation’s ubiquitous convenience food culture.
