Rice could be key ingredient to cutting steel emissions

Steel producers could cut carbon emissions in half by substituting agricultural waste for coal in its production, a world-first trial has found.

Australia–India research advances greener steel manufacturing through agricultural waste trial

Australia’s national science agency, CSIRO, says a world-first trial in India has demonstrated how agricultural waste can partially replace coal in steelmaking, marking a step toward lower-emissions steel production.

Replacing coal with agricultural waste in steelmaking

Image: CSIROResearchers from Australia’s national science agency, CSIRO, and the Indian Institute of Science carried out a trial demonstrating how agricultural waste can partially replace coal in steelmaking, offering a pathway to reduce emissions. Steelmaking accounts for about one tenth of global carbon emissions. India’s sector currently produces an average of 2.55 tonnes of CO₂ per tonne of steel, above the global average, and relies heavily…
