BHP Billiton has partnered with Allonnia, a Bill Gates-backed biotech startup, to investigate the use of rock-eating microbes to address emissions from the steelmaking process.Allonnia has discovered microbes in BHP Billiton’s iron ore that reduce the levels of phosphorus and aluminum in the ore, increasing the grade of the iron ore from 62% to at least 65%. Scaling up these microorganisms could produce direct-reduced iron suitable for steelmaking with hydrogen, which could lead to carbon-free steelmaking.
