PT Trimegah Bangun Persada Tbk (NCKL), better known as Harita Nickel, has reinforced its commitment to sustainable mining by receiving the Change The World award from FORTUNE Indonesia. The honor was presented at the FORTUNE Indonesia Summit 2025, held at The Westin Jakarta on Thursday, February 6.
The Change The World award is a prestigious recognition given to companies that drive positive change through innovation, sustainability, and tangible social impact. Harita Nickel was honored for its nickel slag recycling initiative, transforming industrial by-products into valuable resources for infrastructure development and surrounding ecosystems.
Previously classified as hazardous waste, nickel slag has now been reclassified by the government as non-hazardous, unlocking new opportunities for reuse. The material is being repurposed for road construction within the company’s operational areas, as concrete bricks—used in various Harita Nickel’s operational areas and to build 259 homes in the new settlement of Kawasi Village—and in the creation of 1,700 reef cubes designed to support artificial coral reef ecosystems.
Additionally, Nickel slag is being repurposed as a medium for laterite soil revegetation, reducing compost dependency while improving the efficiency of land reclamation efforts.
Tonny Gultom, Harita Nickel’s Director of Health, Safety, and Environment (HSE), emphasized that this innovative approach not only addresses the accumulation of slag waste but also significantly reduces land reclamation costs, saving between Rp52 million and Rp100 million per hectare. “Through this initiative, we are not only optimizing resource utilization but also reinforcing our commitment to a more responsible nickel industry,” said Tonny.
By the end of 2023, Harita Nickel had recycled 644,234 tons of slag and aims to recycle another 97,000 tons in 2024. This commitment aligns with the company’s efforts to integrate sustainability into its operations, including investing in research and technology to ensure the nickel industry grows responsibly and benefits both the environment and local communities.
