Our Productivity

Achieving milestones for efficiency and sustainability

In 2020, the development of smelter and refinery facilities has progressed up to 25.55%, consistently exceeding the minimum limit set by the government at each semester.

This shows AMIN’s perseverance to comply with government regulations, despite the challenges faced with the onset of the COVID-19 pandemic. AMIN has already been able to secure all required permits for development and advanced technology for effective operations of the facilities. Currently, the company is also working on securing cooperation with several key groups in Indonesia, such as working with Medco Energi on green and renewable energy for use in the development and operations of the smelter and refinery facilities.
