PT Well Harvest Winning Alumina Refinery

What PT Well Harvest Winning Alumina Refinery does

PT Well Harvest Winning Alumina Refinery (WHW) operates Indonesia's first and largest Smelter Grade Alumina (SGA) refinery, located in Kendawangan District, Ketapang Regency, West Kalimantan, on a site of more than 1,000 hectares. The refinery produces SGA with purity greater than 98.6% via the Bayer process refining of bauxite ore, with nameplate capacity of 2 million tons per year following a 2022 expansion from 1 million tons. Supporting infrastructure includes a dedicated coal-fired steam power plant (PLTU) enabling 24-hour operations, an integrated 615,000 M2 special terminal (Terminal Khusus) with a 429 M pier and five port cranes handling up to 90,000 tons of alumina per month, reverse osmosis water treatment, and an apartment-style worker housing complex accommodating roughly 3,000 employees.

WHW is a private foreign-capital (PMA) joint venture between Indonesian and Chinese shareholders — China Hongqiao Group, PT Cita Mineral Investindo (Harita Group), Winning Investment (HK) Company Limited, and Shandong Weiqiao Aluminum & Electricity — with total committed capital of USD 1.3 billion (USD 1.2 billion realised by December 2020) and a workforce of 3,417+ as of December 2023, of whom roughly 86% are sourced locally from Kalimantan Barat. The asset has been designated an Indonesian National Strategic Project (Proyek Strategis Nasional) under Presidential Regulation, anchored by the country's bauxite downstreaming mandate (UU No. 4/2009 as amended by UU No. 3/2020).

Commercially, WHW functions as an industrial B2B commodity supplier, selling SGA via direct enterprise contracts to domestic and international aluminum smelters, with the first export shipment completed in August 2016. Pricing is not publicly disclosed and is negotiated directly with buyers through a dedicated Alumina Inquiry channel on the corporate website. FY2020 revenue was USD 290 million on a 1 million ton capacity base; the 2022 capacity expansion to 2 million tons is the primary driver of subsequent revenue scaling. Ongoing initiatives include a three-scope GHG inventory, red mud and fly ash co-utilisation, and an SMK3 occupational health and safety system that has produced consecutive multi-million-hour accident-free records recognised by regional and ASEAN-level bodies.
