Situated 10km north-west of Gladstone, Yarwun alumina refinery produces 3.4Mtpa of high quality product. Similarly to the QAL facility, where Walz is also engaged, Yarwun uses the world class four stage Bayer process to refine bauxite mined in Weipa on Queensland’s western Cape York. The expanded refinery incorporates a 160Mw cogeneration facility which significantly reduces the operations’ greenhouse gas impact and feeds surplus low emission electricity back into the Queensland electricity grid.

We have been working at the Yarwun refinery for many years and have a strong relationship with the facility’s operations team. With a workforce situated at the site, we provide comprehensive maintenance and shutdown services, as well as general sustainability works. We also support ongoing operations through our piping fabrication, protective coating, and light, medium and heavy fabrication facilities.

Throughout our long standing relationship, we have also completed several major capital works projects. In the last five years, Walz Group has worked with the Rio Tinto Yarwun team to deliver more than 290 projects valued at over $32M.
