Beacon Trusteeship Limited 4C and D Siddhivinayak Chambers, Gandhi Nagar, Opposite MIG Cricket club, Bandra East, Mumbai -400051 GAIL (India) Limited Press Release GMPL, A Wholly Owned Subsidiary of GAIL (India) Limited, Successfully Commissions 1.25 million tons per annum PTA Manufacturing Plant at Mangalore Mangalore, November 5, 2026: GAIL Mangalore Petrochemicals Limited (GMPL), a wholly owned subsidiary of GAIL (India) Limited (GAIL) has successfully commissioned its 1.25 MTPA Purified Terephthalic Acid (PTA) manufacturing plant located in the Mangalore Special Economic Zone (MSEZ), Karnataka. The plant was originally established by JBF Petrochemicals Limited (JBPL), which subsequently underwent Corporate Insolvency Resolution Process (CIRP). In the year 2023, GAIL acquired JBPL through the CIRP, pursuant to the Resolution Plan approved by the National Company Law Tribunal (NCLT) and subsequently undertook extensive revival and refurbishment of the plant. The successful commissioning is the culmination of an extensive revival and refurbishment exercise undertaken by GAIL, involving significant engineering, technological and operational challenges. The successful commissioning represents a significant milestone for GAIL in its strategic endeavour to strengthen its presence in the downstream petrochemical sector. It is a testament to GAIL's commitment, sustained management support and the collective efforts of GMPL-Team, technology partners, consultants, contractors and other stakeholders. This achievement marks not merely the revival of an industrial asset, but the realisation of a strategic vision and the beginning of a new chapter in GAIL's petrochemical growth journey. PTA is a key raw material used in the manufacture of polyester fibre, yarn, PET resin and other polyester-based products, finding extensive applications in the textile, apparel and packaging industries. With an installed capacity of 1.25 million tons per annum, GMPL's facility represents a significant addition to India's domestic PTA manufacturing capacity and is expected to strengthen domestic availability of this critical raw material, reduce import dependence and support the growth of India's downstream polyester industry. Strategically located near New Mangalore Port, the plant is also supported by dedicated logistics infrastructure for efficient movement of raw materials and finished products. GAIL will market the product under the brand name 'G-Tex', leveraging its established marketing network and customer reach.
