CSIRO and IISc Demonstrate Agricultural Waste Use in Steelmaking to Reduce Emissions in India
A trial by CSIRO and the Indian Institute of Science has shown that substituting coal with rice husk pellets in steelmaking can significantly reduce emissions. Conducted at Jindal Steel in Odisha, the test demonstrated that blending 5% and 10% rice husk pellets produced biomass-derived syngas without performance loss. This method could cut India's steel sector emissions by up to 50%, equating to approximately 357 million tonnes of CO₂ annually. This research is part of the India-Australia Green Steel Research Partnership.

Researchers from CSIRO and the Indian Institute of Science conducted a trial in India demonstrating that agricultural waste, specifically rice husk pellets, can partially replace coal in steelmaking. The trial at Jindal Steel in Odisha showed that blending 5% and 10% rice husk pellets into gasifiers maintained syngas production performance.
If widely implemented, this method could reduce emissions in India’s steel sector by up to 50%, potentially lowering CO₂ emissions by about 357 million tonnes annually. Supported by the Australian Government's Green Steel Research Partnership, the project aims to accelerate the adoption of biomass in steel production.
