Story summary

Korean researchers developed a plasma conversion process that recycles mixed waste plastics into raw materials, achieving over 70% yield of high-purity ethylene and benzene at 1,000–2,000 °C. This aims to boost Korea's chemical recycling rate, currently below 1%.
Japan introduced an electron beam technology that efficiently recycles PTFE, achieving up to 86% decomposition while reducing energy consumption.
Both technologies promote sustainable recycling practices to combat environmental challenges from persistent materials.
