Rio Tinto launches biofuel crop farming trial for renewable diesel production

Rio Tinto will develop Pongamia seed farms in Australia as part of a new biofuels pilot.
The project will explore the potential of Pongamia seed oil as a feedstock for renewable diesel, a cleaner alternative to traditional fossil fuels.
The pilot aims to determine if the seed oil can contribute to Rio Tinto's renewable diesel needs while potentially contributing to the growth of a new biofuel sector in Australia.
Rio Tinto is in the final stages of acquiring approximately 3,000 hectares of cleared land near Townsville in north Queensland to establish farms to study growth conditions and measure seed oil yields.
Rio Tinto has partnered with Midway Limited, to oversee the planting and management of the seed farms.
Rio Tinto chief decarbonisation officer Jonathon McCarthy said: “Diesel accounts for around 10% of our emissions footprint in Australia.
“While we continue to pursue electrification as the long-term solution for displacing the majority of our diesel use, the Pongamia seed pilot is an important parallel pathway that could reduce our reliance on diesel in the mid-term. It also presents a compelling option for other applications that are challenging to electrify, including blasting and non-haul equipment.
“Australia does not yet have a biofuel feedstock industry sufficient to meet domestic demand. A sustainable biofuels industry here could enhance the region’s fuel security, create local economic opportunities, and contribute to emissions reductions targets.”
Midway Limited managing director Tony McKenna said: “We are very excited to be partnering with Rio Tinto on this innovative pilot project. We are proud to be playing an important role in helping develop a sustainable domestic biofuel industry.
“The collaboration continues the growth of our position as trusted providers with the capability and experience to deliver a variety of projects for emitters who are committed to seeking alternative solutions to reduce their net emissions.”
This pilot follows a smaller-scale trial at Rio Tinto Gove operations in the Northern Territory where Pongamia saplings were planted to learn more about their response to low soil quality, heat and other climatic conditions in northern Australia.
