Rio Tinto tests biofuel crop for diesel in Australia

Rio Tinto has announced an investment in Pongamia seed farms in Australia to explore the potential of using the oil from these seeds as a feedstock for renewable diesel. This initiative is part of the company's broader strategy to reduce its reliance on fossil fuels, which currently contribute to approximately 10% of its emissions in Australia. The company aims to achieve net-zero Scope 1 and 2 carbon emissions by 2050, with electrification being the long-term solution for replacing diesel in its operations. However, in the interim, Rio Tinto is seeking quicker alternatives to lower emissions from diesel sources, such as biofuels. The partnership with Midway Limited will facilitate the planting and management of the Pongamia farms, which are expected to play a crucial role in developing a biofuel feedstock industry in Australia. Currently, the country lacks the infrastructure to meet domestic biofuel demand, and this pilot project is seen as a significant step towards addressing that gap. The seeds of the Pongamia tree, native to northern Australia, can be processed into renewable diesel, which has a much lower carbon footprint compared to traditional fossil diesel. In addition to this biofuel initiative, Rio Tinto is also making strides in other areas of sustainability. The company has transitioned its Boron operation in California to renewable diesel, becoming the first open-pit mine globally to achieve this milestone. Furthermore, it plans to replicate this success at its Kennecott copper operation in Utah. Overall, these efforts reflect Rio Tinto's commitment to decarbonization and its proactive approach to reducing emissions while exploring innovative solutions in the mining sector.
