Belagavi, Aug 27: Hindalco Industries Limited, the metals flagship of the AdityaBirla Group, hascommissioned agreenfieldSuperfine PPT ATH manufacturing plant in Belagavi, Karnataka, bringing domestic production of this high-valuespecialtyaluminaproducttoIndiaforthefirsttime.Thenewfacility,with anannual 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 speciality 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 cables, polymer insulators, thermal insulation, composites and paints. In applications such as cables, it helps suppress flame propagation and smoke generationwithout 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 meetalmosttheentiredomesticdemandforsafercablesfromthe wireandcableindustry, 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.
Satish Pai, Managing Director, Hindalco Industries, said,
“The commissioning of our Superfine precipitated hydrate plant in Belagavi will further strengthen our leadership position, and enhance our high-value specialty alumina portfolio in India. This investment reflects Hindalco’s focus on creating value, moving up the value chain and delivering advanced solutions that meet the emerging needs of customers in India and global markets.”
Saurabh Khedekar, CEO, Alumina Business, Hindalco Industries, said,
“The addition of Superfine PPT ATH strengthens our Specialty Alumina portfolio and reinforces our focus on innovation-led growth. Our InnoSafe solution enhances fire safety by retarding flame spread and suppressing smoke, enabling safer and more sustainable infrastructure. As India’s first manufacturer of Superfine Precipitated Hydrate, we are proud to offer an indigenous, world-class solution that strengthens self-reliance, reduces import dependence and supports the evolving needs of the wire and cable industry.”
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.
