BHP Step Change

BHP contracted MEC to conduct an opportunity assessment aimed at identifying strategies to achieve a substantial reduction in carbon emissions, aligning with their ambitious net-zero 2050 target across their WAIO Operations. MEC initiated the process by developing a comprehensive baseline emissions model, spanning the lifecycle of assets. This model served as the foundation for evaluating various innovative technologies, including In-Pit Crushing and Conveying, Excavator Electrification, Trolley Assist, and the groundbreaking Small Autonomous Battery Electric Truck Fleet, known as the SWARM Principle. These technologies were strategically selected to directly mitigate emissions and facilitate the early adoption of renewable energy sources.

Drawing upon our expertise in the field, MEC meticulously crafted practical and pragmatic solutions for the implementation of each technology. These solutions were designed not only to achieve significant reductions in emissions but also to uphold or enhance Business as Usual (BaU) production and quality, operational productivity, and ore recovery, while simultaneously reducing strip ratios through minimised waste mining. The study revealed emission reduction opportunities of up to 50% compared to the baseline across the spectrum of technology options, highlighting the potential for substantial environmental impact while maintaining operational excellence.
