Advancing circularity and asset efficiency

The Thiess Rebuild Centre on Batam Island, Indonesia, is a strategic hub for rebuilding mining equipment that supports our operations across Asia and Australia

Now in its second year of operation, the Centre has successfully completed the rebuild of 54 Caterpillar 785 and 789 trucks – each incorporating product updates, technology enhancements and composite solutions (see Asset life extension) to improve productivity, reduce emissions and extend asset life.

The rebuild approach reflects our commitment to circular economy principles – prioritising reuse and recycling over replacing. The Centre also enables us to explore decarbonisation options for mining equipment and develop innovative solutions while lower-emission truck technologies continue to mature.

The rebuild program results in a significant reduction in environmental impacts. Rebuilding 54 trucks reused approximately 1,671 tonnes of steel in major components, avoiding up to 2,986 tonnes of CO²-e compared to manufacturing new trucks. Of the remaining 7.2 tonnes of steel in the major components, 6.5 tonnes were recycled. This process also reduces emissions and costs associated with transporting new trucks, reduces new part pipeline requirements and supports specialised local services that support the Centre minimising supply chain risks.

The Batam team continues to build capability to increase the number of salvaged and reused parts, with the aim of further enhancing cost efficiency and sustainability outcomes for the Group.
