The new facility, with an annual produc(cid:415)on capacity of 30,000 tonnes, strengthens Hindalco’s Specialty Alumina por(cid:414)olio and advances the country’s journey towards Atmanirbhar Bharat in cri(cid:415)cal fire-safety applica(cid:415)ons. The facility is also the world’s only speciality alumina plant to operate en(cid:415)rely on renewable energy, se(cid:427)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(cid:415)on, composites and paints. In applica(cid:415)ons such as cables, it helps suppress flame propaga(cid:415)on and smoke genera(cid:415)on without releasing halogen acid gases, suppor(cid:415)ng safer electrical and infrastructure systems. Demand is growing with stricter fire-safety standards, rising EV and infrastructure adop(cid:415)on, and the shi(cid:332) towards sustainable, high-performance materials. Further, BIS has introduced IS 17048:2018 for HFFR cables, aligning Indian standards with global safety benchmarks and suppor(cid:415)ng wider adop(cid:415)on across infrastructure, electrical and mobility applica(cid:415)ons. Against this backdrop, the plant’s Phase 1 capacity of 30,000 tonnes per annum is designed to meet almost the en(cid:415)re domes(cid:415)c demand for safer cables from the wire and cable industry, an important step in self-reliance for this cri(cid:415)cal material. The facility is designed for phased expansion to 60,000 tonnes, enabling Hindalco to scale capacity in line with domes(cid:415)c market growth. Sa(cid:415)sh Pai, Managing Director, Hindalco Industries, said, “The commissioning of our Superfine precipitated hydrate plant in Belagavi will further strengthen our leadership posi(cid:415)on, and enhance our high-value specialty alumina por(cid:414)olio in India. This investment reflects Hindalco’s focus on crea(cid:415)ng value, moving up the value chain and delivering advanced solu(cid:415)ons that meet the emerging needs of customers in India and global markets.” Saurabh Khedekar, CEO, Alumina Business, Hindalco Industries, said, “The addi(cid:415)on of Superfine PPT ATH strengthens our Specialty Alumina por(cid:414)olio and reinforces our focus on innova(cid:415)on-led growth. Our InnoSafe solu(cid:415)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(cid:415)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 innova(cid:415)on journey, with technology and R&D developed in-house from the ground up. The plant incorporates automated controls for cri(cid:415)cal processes and a fully integrated manufacturing ecosystem, enabling stringent control over feedstock quality and product consistency. Sustainability is another key differen(cid:415)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(cid:415)on of high-performance specialty materials with a lower environmental footprint. By combining domes(cid:415)c manufacturing, in-house innova(cid:415)on, stringent quality control and sustainable produc(cid:415)on, the plant strengthens India’s capability to develop advanced materials for the next genera(cid:415)on of fire-safe electrical and mobility applica(cid:415)ons.
