Rio Tinto has started growing pongamia trees in northern Australia, as part of a biofuels project aimed at reducing the mining giant’s reliance on fossil fuels. Pongamia trees are native to Australia and produce oil-rich seeds that can be processed into renewable diesel… Earlier this year, Rio Tinto trialled 10 million litres of renewable diesel — created from used cooking oil — across its Pilbara iron ore operations in Western Australia. The biofuel got used across the supply chain, featuring in Rio Tinto’s rail, marine, haul trucks, surface mining equipment and light vehicles… Forestry Industry Association of the Northern Territory (FIANT) manager Hanna Lillicrap said it was great to see a major mining company getting involved in the forestry sector. “It reflects a growing recognition of the role forestry can play as a climate-positive solution in emissions reduction strategies,” she said. “It’s great to see serious investment going into research to better understand the species and its potential,” she said.
