The facility is also the world’s only speciality alumina plant to operate en rely on renewable energy, se ng 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 insula on, composites and paints. In applica ons such as cables, it helps suppress flame propaga on and smoke genera on without releasing halogen acid gases, suppor ng safer electrical and infrastructure systems. Demand is growing with stricter fire-safety standards, rising EV and infrastructure adop on, and the shi towards sustainable, high-performance materials.
Further, BIS has introduced IS 17048:2018 for HFFR cables, aligning Indian standards with global safety benchmarks and suppor ng wider adop on across infrastructure, electrical and
mobility applica ons.
Against this backdrop, the plant’s Phase 1 capacity of 30,000 tonnes per annum is designed to meet almost the en re domes c demand for safer cables from the wire and cable industry,
an important step in self-reliance for this cri cal 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 posi on, and enhance our high-value specialty alumina por olio in India. This investment reflects Hindalco’s focus on crea ng 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 por olio and reinforces our focus on innovation-led growth. Our InnoSafe solu on 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 solu on 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 differen ator 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 produc on of high-performance specialty materials with a lower environmental footprint.
By combining domes c manufacturing, in-house innovation, stringent quality control and sustainable production, the plant strengthens India’s capability to develop advanced materials for the next genera on of fire-safe electrical and mobility applications.
