Hindalco Commissions India’s First Superfine PPT ATH Plant, Strengthens Self-Reliance in Cable Fire Safety
Karnataka, 27 August 2026: Hindalco Industries Limited, the metals flagship of the Aditya Birla Group, has commissioned a greenfield Superfine PPT ATH (Precipitated Aluminium Trihydrate) manufacturing plant in Belagavi, Karnataka, bringing domestic production of this high-value specialty alumina product to India for the first time.
The new facility, with an annual production capacity of 30,000 tonnes, strengthens Hindalco’s Specialty Alumina portfolio and advances the country’s journey towards Atmanirbhar Bharat in critical fire-safety applications.
The facility is also the world’s only specialty alumina plant to operate entirely on renewable energy, setting a global benchmark for sustainable manufacturing.
PPT ATH is a high-value, halogen-free flame-retardant material used in Halogen-Free Flame Retardant (HFFR) cables, polymer insulators, thermal insulation, composites, and paints. In applications such as cables, it helps suppress flame propagation and smoke generation without releasing halogen acid gases, supporting safer electrical and infrastructure systems.
Demand is growing with stricter fire-safety standards, rising EV and infrastructure adoption, and the shift towards sustainable, high-performance materials. Further, BIS has introduced IS 17048:2018 for HFFR cables, aligning Indian standards with global safety benchmarks and supporting wider adoption across infrastructure, electrical, and mobility applications.
Against this backdrop, the plant’s Phase 1 capacity of 30,000 tonnes per annum is designed to meet almost the entire domestic demand for safer cables from the wire and cable industry, an important step in self-reliance for this critical material. The facility is designed for phased expansion to 60,000 tonnes, enabling Hindalco to scale capacity in line with domestic market growth.
The facility has been developed through Hindalco’s flask-to-factory innovation journey, with technology and R&D developed in-house from the ground up. The plant incorporates automated controls for critical processes and a fully integrated manufacturing ecosystem, enabling stringent control over feedstock quality and product consistency. Sustainability is another key differentiator of the facility.
The PPT ATH is produced at Hindalco’s Belagavi refinery, which achieved a GHG intensity of 0.44 tCO₂e per tonne of alumina (YTD FY26). The facility is powered by 100% renewable energy from biomass, solar, and wind sources, enabling the production of high-performance specialty materials with a lower environmental footprint.
