Hindalco Industries Limited, the metals flagship of the Aditya Birla Group, commissioned India’s first greenfield Superfine Precipitated Aluminium Trihydrate (PPT ATH) manufacturing plant on 27 August 2026. The facility is located in Belagavi, Karnataka, and marks domestic production of a specialty alumina material used in fire-safety applications.
Superfine Precipitated Aluminium Trihydrate
Precipitated Aluminium Trihydrate is an aluminium hydroxide-based mineral compound used as a flame-retardant filler in polymers. Superfine PPT ATH is used in halogen-free flame-retardant materials, polymer insulators, and thermal insulation products.
Plant Capacity and Expansion
The Phase 1 annual production capacity of the plant is 30,000 tonnes. The facility has been designed for phased expansion to 60,000 tonnes per year, which is double the initial capacity.
Renewable Energy and Manufacturing Features
The plant is described as the world’s only specialty alumina plant powered entirely by renewable energy. Its energy mix includes solar, wind, and biomass power, and the facility uses fully automated process controls under Hindalco’s in-house “flask-to-factory” R&D and technology programme.
Important Facts for Exams
- Hindalco Industries Limited is part of the Aditya Birla Group and operates in the metals sector.
- Belagavi is a city in Karnataka and is the location of the new PPT ATH plant.
- HFFR stands for halogen-free flame-retardant, a category used in cable insulation and safety materials.
- Precipitated Aluminium Trihydrate is also known as ATH and is used as a flame-retardant additive in polymers.
Industrial and Strategic Use
Superfine PPT ATH is used in HFFR cables, polymer insulators, and thermal insulation to suppress flames and reduce toxic acid gas emissions. The domestic plant is linked to reduced import dependence for electrical, infrastructure, and electric vehicle applications.
