Hindalco Industries, an Aditya Birla Group company, has commissioned a greenfield Superfine PPT ATH (Precipitated Aluminium Trihydrate) manufacturing plant in Karnataka, bringing domestic production of this high-value specialty alumina product to India for the first time. The new facility, with an annual production capacity of 30,000 tonnes, strengthens Hindalco’s Specialty Alumina portfolio in critical fire-safety applications.
The facility is also the world’s only speciality alumina plant to operate entirely on renewable energy.
PPT ATH is a high-value, halogen-free flame-retardant material used in Halogen-Free Flame Retardant cables, polymer insulators, thermal insulation, composites and paints.
Growing demand for fire-safe materials
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 is growing with stricter fire-safety standards, rising EV and infrastructure adoption, and the shift towards sustainable, high-performance materials.
Further, BIS has introduced IS 17048:2018 for HFFR cables, aligning Indian standards with global safety benchmarks and supporting wider adoption across infrastructure, electrical and mobility applications.
Plant designed to meet domestic demand
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, an important step in self-reliance for 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 new plant will further strengthen the company’s leadership position and enhance the high-value specialty alumina portfolio in India.
The 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, he added.
Indigenous technology and renewable energy
Saurabh Khedekar, CEO, Alumina Business, Hindalco Industries said 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 is an indigenous solution that strengthens self-reliance, reduces import dependence and supports the evolving needs of the wire and cable industry, he added.
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.
The facility is powered entirely by renewable energy from biomass, solar and wind sources, enabling the production of high-performance specialty materials with a lower environmental footprint.
