As a key supplier to the EV battery chain, Harita Nickel ties growth to carbon‑smart operations. At its PT Halmahera Persada Lygend (HPL) HPAL plant on Obi Island, a waste‑heat recovery (WHR) system now converts exhaust heat into electricity, saving energy equivalent to 9 million litres of gasoline annually and avoiding 307,988 t CO₂e.
Circular thinking extends to the cafeteria. Harita Nickel has also taken a novel approach to waste by repurposing used cooking oil—generated from meal services for its 20,000 employees—into an alternative fuel for smelter operations. The reused oil replaces approximately 21% of thermal coal calories each day, reducing daily coal consumption by up to 10 metric tons. Director of Health, Safety and Environment (HSE) Tonny Gultom says the pilot program could be expanded if proven to be technically viable over the long term.
In the Obi Industrial Estate, Harita Nickel has installed solar panels for street lighting, generating 98 gigajoules of energy and cutting emissions by 42.83 tons of CO2e. Since 2023, biodiesel has also been used for transportation and power generation, yielding 908,220 gigajoules of energy and avoiding up to 45,011 tons of CO2e emissions.
Tonny emphasized that sustainability is the foundation of the company’s operations. “Responsible mining must deliver long-term benefits, not just economically, but also socially and environmentally,” said Tonny.
Harita Nickel’s commitment to responsible practice is also reflected with a net-zero emissions target by 2060, ISO 14001 and ISO 45001 certifications under its belt, and other future energy efficiency projects. With these, Harita Nickel proves its strategic role as a pioneer of sustainable mining in Indonesia.
