Who we are

The chemical flagship of the PTT Group.

Formed in 2012 from the amalgamation of PTT Chemical and PTT Aromatics & Refining, GC integrates a world-scale refinery with olefins, aromatics, polymers and a fast-growing portfolio of green and specialty chemicals.

One value chain, five business groups — from the first molecule of crude and condensate to the materials that move modern life.

What we do

Five integrated
business groups

View all businesses →
01 · REFINERY

Refinery

280,000 bbl/day of crude and condensate — the feedstock backbone producing fuels, naphtha, jet, diesel and aromatics precursors.
02 · OLEFINS

Olefins

Ethane-based ethylene and propylene — the lowest-cost feedstock advantage in the region, cracked into the molecules everything is built from.
03 · AROMATICS

Aromatics

Benzene, paraxylene and toluene — feeding polyester, fibres, packaging and engineering plastics worldwide.
04 · POLYMERS

Polymers

HDPE, LLDPE and polypropylene under InnoPlus & DIAREX — resins for packaging, automotive and consumer goods.
05 · GREEN & SPECIALTY

Green & Performance

Bioplastics, recycled resins and specialty chemicals — NatureWorks, ENVICCO and allnex. The growth engine →

Molecule to market

One integrated value chain

Integration is GC's edge: every stage feeds the next, capturing margin and carbon efficiency from the wellhead molecule to the finished material.

STAGE 01

Crude & Condensate

Feedstock sourced through PTT, including low-cost ethane.

STAGE 02

Refinery

280k bbl/day into fuels, naphtha & aromatics precursors.

STAGE 03

Olefins & Aromatics

Cracking & extraction into building-block molecules.

STAGE 04

Polymers & Derivatives

Resins, EO/EG, phenol & performance materials.

STAGE 05

Market

Packaging, mobility, healthcare & green materials worldwide.

Generation Sustainability

Net Zero by 2050.

A clear roadmap built on three levers — efficiency, portfolio and carbon compensation — and ranked the world's No.1 chemical company for sustainability by S&P Global.

Innovation & specialty

Higher-value molecules, lower-carbon future

Bio & circular

NatureWorks Ingeo PLA and ENVICCO recycled resins — a fully integrated PLA complex at Nakhon Sawan online by 2026.

Sustainable Aviation Fuel

SAF production commissioned at the Map Ta Phut refinery in 2025 — new low-carbon value from existing assets.

Performance materials

allnex eco-friendly coating resins and high-value specialties — targeting 35% of long-term EBITDA from performance chemicals.

Investors

Built for the long cycle

A 'Holistic Optimization' strategy targets THB 4.5 billion in annual value through efficiency and portfolio quality — disciplined through the chemical trough.
