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, marking the first domestic production of this high-value specialty alumina product in India.
The new facility has an annual production capacity of 30,000 tonnes and strengthens Hindalco’s Specialty Alumina portfolio while advancing India’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 for PPT ATH is growing due to stricter fire-safety standards, rising EV and infrastructure adoption, and the shift towards sustainable, high-performance materials. The Bureau of Indian Standards (BIS) has also 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. This represents an important step towards self-reliance in 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.
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 in YTD FY26. The facility is powered by 100% renewable energy sourced from biomass, solar and wind, enabling the production of high-performance specialty materials with a lower environmental footprint.
By combining domestic manufacturing, in-house innovation, stringent quality control and sustainable production, the plant strengthens India’s capability to develop advanced materials for the next generation of fire-safe electrical and mobility applications.
