At the 2025 Indonesia Mining Conference & Critical Metals Conference - 2025 Southeast Asia Tin Industry Conference, hosted by SMM Information & Technology Co., Ltd. (SMM), supported by the Indonesian Ministry of Foreign Affairs as a government supporter, and co-organized by the Association of Indonesian Nickel Miners (APNI), the Jakarta Futures Exchange, and China Coal Resource, Aryo Djojohadikusumo, CEO of PT Arsari Tambang, shared insights on the theme "Innovation for Sustainable Development: Arsari Tambang's Vision for the Future of the Green Critical Minerals Industry."

►The Roots of Indonesia's Tin Industry

PT Timah Tbk, established in 1976 as a state-owned enterprise (BUMN), marks a significant milestone in Indonesia's tin industry.

Arsari Tambang is Indonesia's largest private tin mining company, holding a 2,175-hectare mining concession on Bangka Island.

Arsari Tambang is an integrated tin mining company covering the entire tin production chain, from exploration, mining, smelting, refining to tin metal production, and beyond to tin downstream products. Its tin solder production line just commenced operations in June 2025, with plans to develop tin plate products in the future.

Arsari Tambang is an end-to-end integrated tin mining company and the first private enterprise to lead post-mining ecological restoration in the Bangka Belitung Province.

Arsari Tambang sells high-quality tin ingots while adhering to environmental and safety standards.

The company also elaborated on its environmental restoration plans and provided relevant case studies.

►Arsari Tambang is Poised to Become Indonesia's First Tin Mining Company to Achieve Net-Zero Emissions

Transitioning to renewable energy (REC) electricity certified by Indonesia's state electricity company (PLN); to achieve sustainable tin ingot production, the company is shifting its fuel source to electric furnaces and utilizing renewable electricity sources such as hydropower and geothermal energy; transitioning to renewable energy-based power generation.

Commitment to Developing the Tin Downstream Industry

Arsari Tambang is dedicated to developing downstream tin industry businesses, in line with the initiative of President Prabowo Subianto of the Republic of Indonesia to promote the downstream processing of natural resources for the benefit of the Indonesian people.

Global Surge in Downstream Tin Demand

It is projected that downstream tin demand will grow by approximately 25% by 2030, primarily driven by solder demand. By 2030, the world will require an additional 61,000 mt/year of tin solder, with 17,000 mt/year coming from ASEAN countries.

Vision

To become the first truly environmentally friendly tin producer in ASEAN and beyond.

Stania is a concrete manifestation of Arsari Tambang's commitment to developing the downstream tin industry.

The Stania factory, with an annual production capacity of 2,000 mt of tin solder rods, is located in the Tunas Industrial Zone on Batam Island and officially commenced operations on May 25, 2025.

STANIA's Vision Roadmap

The glow from molten tin droplets illuminates our digital future.

Tin plays a crucial role in generating extreme ultraviolet (EUV) light, which is the core element enabling ASML's cutting-edge High Numerical Aperture (High NA) EUV lithography technology for advanced chip production.
