Borneo Alumina Indonesia

What Borneo Alumina Indonesia does

PT Borneo Alumina Indonesia (PT BAI) is an Indonesian state-owned enterprise and subsidiary of the MIND ID state mining holding group, operating alongside parent companies PT INALUM (Indonesian Asahan Aluminium) and PT ANTAM Tbk (Aneka Tambang). The company runs the Smelter Grade Alumina Refinery (SGAR) in Mempawah, West Kalimantan, which was inaugurated by President Joko Widodo in September 2024 with a designed Phase 1 capacity of 1 million tons per year of Smelter Grade Alumina (SGA). SGAR processes domestically mined bauxite ore into high-purity alumina (Al2O3) via the Bayer process, supplying feedstock for aluminum electrolytic smelting and supporting Indonesia's national mineral downstream processing (hilirisasi) strategy.

The company's core product is Smelter Grade Alumina, marketed under the "PURE" high-purity branding, sold through direct B2B enterprise sales to aluminum manufacturers both domestically and internationally. PT BAI completed its first production and 16 trial shipments (domestic and export) by end-2025, with full commercial production targeting the 1 million tons per year Phase 1 capacity. Pricing is negotiated on multi-year industrial contracts and is not publicly disclosed. The primary customer is its parent company PT INALUM as off-take buyer, with PT ANTAM participating in project governance under the MIND ID holding.

Beyond alumina refining, PT BAI maintains an extensive CSR and community engagement program in West Kalimantan, including MSME mentorship in collaboration with the Indonesian Ministry of MSMEs (KUMKM), welder training programs with local government bodies, and quarterly blood donation drives. The company is currently preparing the Feasibility Study for SGAR Phase 2 expansion to scale capacity beyond the Phase 1 baseline, with corporate headquarters in Jakarta and operational headquarters at the Mempawah refinery site.
