Hindalco Industries has launched a 30,000 tonnes-per-annum Superfine Precipitated Aluminium Trihydrate (PPT ATH) facility in Belagavi. As India's first plant for this high-value flame-retardant material, it aims to reduce import dependence while catering to growing demand in the EV and infrastructure sectors. Powered entirely by renewable energy, the facility is designed for future scaling up to 60,000 tonnes.
Hindalco Commissions India's First Superfine PPT ATH Plant
Initial Capacity: 30,000 Tonnes Per Annum | Planned Scaling: 60,000 Tonnes Per Annum
Reader Takeaway: This capacity expansion boosts domestic supply of high-value flame-retardants, positioning Hindalco to capture rising industrial and EV demand.
What just happened
Hindalco Industries has successfully commissioned a greenfield manufacturing plant for Superfine Precipitated Aluminium Trihydrate (PPT ATH) in Belagavi, Karnataka. This is the first facility of its kind in India. The plant currently holds a capacity of 30,000 tonnes per annum with infrastructure designed for a future expansion to 60,000 tonnes as domestic demand increases.
Why this matters
PPT ATH is a premium, halogen-free material essential for fire safety. It is critical for the production of HFFR cables, polymer insulators, and thermal insulation. By producing this domestically, Hindalco is directly addressing the country’s reliance on imports for these safety-critical materials. The expansion aligns with the company's broader strategy to climb the value chain into high-margin specialty products.
Sustainability
The new plant operates exclusively on 100% renewable energy, utilizing a combination of biomass, solar, and wind power. This move reinforces Hindalco’s commitment to lowering its greenhouse gas footprint, with the Belagavi refinery reporting a GHG intensity of 0.44 tCO2e per tonne of alumina for the year-to-date in FY26.
What to track next
Investors should look for updates on capacity utilization rates and the contribution of this specialty alumina segment to overall revenue margins in upcoming quarterly filings. The company's ability to capture market share from international suppliers will be a key performance indicator.
