PTT Global Chemical (GC) and Siam Piwat Group have expanded their "From Kitchen to Flight" project by collecting used cooking oil from restaurants within Siam Paragon, Siam Center, and Siam Discovery shopping malls. This collected oil will be processed at GC's biorefinery to produce sustainable aviation fuel (SAF) and other high-value bioproducts.

This collaboration extends GC's circular economy model to the business sector, reinforcing Siam Piwat's commitment to integrated waste management and sustainability goals, including achieving Zero Waste to Landfill by 2040.
