Plastic trash turned into high-quality jet fuel with new atomic-scale catalyst

SMRTR summary

Researchers from Nanjing and Tsinghua universities developed a two-stage process converting waste polystyrene plastic into jet fuel using atomic-scale catalysts, operating at lower temperatures and pressures than previous methods. The process is estimated to produce fuel competitively priced at $1.00–$1.80 per kilogram, though large-scale production remains unproven.
