Project description
Building a carbon-free, zero-waste future for the steel industry
Today’s steel industry uses billions of tonnes of iron ore. There is growing demand for high-quality ores and scrap (recycled) steel as well as novel technological approaches for upgrading low-grade iron ores and recycling of mill scale. In this context, the EU-funded TransZeroWaste project will apply hydrometallurgy for mill scale de-oiling and use this iron-rich scrap equivalent to upgrade low-grade iron ores. Specifically, the project will develop low-carbon technologies such as cold pelletising and briquetting, hot microwave pelletising and magnet-supported hydrometallurgy. The applied research will be developed and transferred to the two industrial partners with nine production sites. Overall, the project will bring the European steel industry to the carbon-free, zero-waste future.
Objective
Growing demand for high quality iron ores and scrap as well as abandonment of carbon intensive sintering in the future require novel technological approaches for upgrading of low-grade iron ores and recycling of mill scale. TransZeroWaste will apply hydrometallurgy for mill scale de-oiling and use this iron-rich scrap equivalent to upgrade low-grade iron ores. For that, TransZeroWaste will develop low carbon technologies such as cold pelletising and briquetting, hot microwave pelletising, and magnet-supported hydrometallurgy from TRL 6 to TRL 8. The developed technologies will be transferable to further material flows such as dusts and sludges.
On European level, the expected impact will be the potential upgrade of over 18 million t/a low-grade iron ore, up to 6 million t/a mill scale and 3 million t/a pellet sieving residue. Total impact of TransZeroWaste will include upgrading of 27 million t/a materials with low carbon technologies and avoiding of corresponding sinter plant carbon footprint of 4,3 – 9,9 MtCO2/a.
Technological competences and know-how are owned by the participating partners from the applied research. They will be developed and transferred to the two industrial partners with 9 production sites. Thoroughly planned dissemination and exploitation activities will ensure effective implementation of technologies after project end. Life cycle assessment and economic evaluation will be performed; sustainable business models will be developed. Furthermore, a decision support platform for industrial users will be installed. In combination with workshops and trainings it will help to find and implement the best upgrading technology for various low-grade materials considering environmental and economic aspects. TransZeroWaste will serve as a vehicle for the transition of the European steel industry to the carbon free zero waste future.
