Thailand Biodiesel & Renewable Diesel Market Intelligence

Thailand consumed roughly 4.4 million litres of B100 methyl ester per day in 2024 (~1.6-2.1 million tonnes per year), absorbing 30-35% of domestic CPO supply through the B7 plus B20 mandate. Bangchak Corporation (SET: BCP) anchors capacity via the BBE Ayutthaya joint venture with UAC and now operates ASEAN's first commercial HEFA SAF unit at Phra Khanong, supported by the Fry to Fly used-cooking-oil collection programme. PTT Group, Thai Oil (SET: TOP), IRPC (SET: IRPC) handle refinery-gate blending; Verasuwan, PA Renewable Energy, Patum Vegetable Oil and other specialty plants hold the long tail. The AEDP 2024-2037 roadmap fixes B7 as the diesel floor, ramps SAF from 1% (January 2026) to 8% (2036), and frames the structural variables: EV diesel-pool erosion, EUDR palm-traceability compliance, and HVO drop-in renewable diesel as the next-leg pivot.
